Yesterday Newt Gingrich revealed his “weirdest idea ever” — to provide a path to statehood for a hypothetical lunar colony.

With the help of the skilled research librarians in the Library of Congress Law Library, BuzzFeed tracked down the bill, which Gingrich called the “Northwest Ordinance for Space,” or formally the “National Space and Aeronautics Policy Act of 1981.”

“The Congress declares that the United States is committed to the expansion of free people and free institutions into space,” the bill stated, calling for an array of near earth and solar space travel vehicles to be completed by 2010.

It also called for the creation of “an environmentally acceptable space to Earth power capability that is economically competitive with power generation on Earth,” by the year 2000.

Professor Frederic Pont, of the University of Exeter, imagined what it might really look like if a person were able to visit another planet and to then sit quietly watching as the sun set. He used data from a camera onboard Hubble, knowledge of how the color of light changes based on chemicals it encounters, and computer modeling, to create an actual image of what a sunset on an actual planet far out in space would look like. The planet in question, exoplanet HD209458b, nicknamed Osiris, just happens to be quite large and circles its star rather closely.

Though we couldn’t technically sit on the surface of Osiris, since it doesn’t have one, the picture that Pont produced approximates what it would look like, and the results are truly beautiful. The light from Osiris’s star is white, like our own sun, but when it passes through the sodium in Osirisi’s atmosphere, red light in it is absorbed, leaving the starlight to appear blue. But then, as the sun sets, the blue light is scattered in the same way as it is here on Earth (Rayleigh scattering) causing a gradual change to green, and then to mushy dark green. And finally, due to diffraction, the bottom of the image becomes slightly flattened.

Researchers have released the biggest images yet detailing dark matter, the mysterious substance that makes up three-quarters of the Universe’s mass.

Each image, a billion light-years across, shows vast dark matter clumps and voids scattered through the cosmos.

The team from the Canada-France Hawaii Telescope inferred the dark matter’s existence by the way it bends light.

The images were presented at the 219th meeting of the American Astronomical Society in Austin, US.

The four images were taken at four different seasons of the year, each capturing a swath of the sky about as large as a palm held at arm’s length.

They are a big step forward in understanding both dark matter itself, and the means by which dark matter influences the way normal matter clumps into the galaxies we see in the night skies.

Together, they represent the images of more than 10 million galaxies, whose light gives the only hints of the large-scale structure of dark matter…

The Earth has always had a temporary second moon, new study has claimed. When astronomers caught sight of a mysterious titanium white object circling around the Earth in 2006, they assumed it was a spent rocket. But it was actually a small asteroid captured by the Earth’s gravitational field that rotated around the Earth until June 2007.

In the new study, astrophysicists at Cornell claim that this little moon was not an anomaly as these asteroids come and go so often it means our planet always has a temporary second moon.

According to Cornell University’s Mikael Granvik, Jeremie Vaubaillon and Robert Jedicke, they have calculated the population of “irregular natural satellites that are temporarily captured” by Earth.

In their study, researchers say that while these moons are small, the scientific implications of this discovery are phenomenal. Instead of having to send crews to asteroids astronomers can wait until they come closer to Earth to intercept and learn more about the origins of our solar system.

Forget Kenya. Never mind the secret madrassas. The sinister, shocking truth about Barack Obama’s past lies not in east Africa, but in outer space. As a young man in the early 1980s, Obama was part of a secret CIA project to explore Mars. The future president teleported there, along with the future head of Darpa.

That’s the assertion, at least, of a pair of self-proclaimed time-traveling, universe-exploring government agents. Andrew D. Basiago and William Stillings insist that they once served as “chrononauts” at Darpa’s behest, traversing the boundaries of time and space. They swear: A youthful Barack Obama was one of them.

Perhaps this all sounds fantastical, absurd, and more than a little nuts. We couldn’t agree more. That’s one of the reasons we love conspiracy theories — the more awesomely insane, the better. Each week during 2012, when the Mayans tell us to expect the apocalypse, Danger Room will peel back a new layer of crazy to expose those oh-so-cleverly hidden machinations powering this doomed plane of existence. Welcome — back — to Tinfoil Tuesday…

What a relief! (I wonder if this woman’s Pleiadian lover knew about this?)

A large metallic ball fell out of the sky on a remote grassland in Namibia, prompting baffled authorities to contact NASA and the European space agency.

The hollow ball with a circumference of 1.1 metres (43 inches) was found near a village in the north of the country some 750 kilometres (480 miles) from the capital Windhoek, according to police forensics director Paul Ludik.

Locals had heard several small explosions a few days beforehand, he said.

With a diameter of 35 centimetres (14 inches), the ball has a rough surface and appears to consist of “two halves welded together”.

It was made of a “metal alloy known to man” and weighed six kilogrammes (13 pounds), said Ludik…

Scientists claim to have produced particles of light out of vacuum, proving that space is not empty.

An international team says that its ingenious experiment in which tiny parcels of light, or photons, are produced out of empty space has confirmed that a vacuum contains quantum fluctuations of energy, the ‘Nature’ journal reported.

In fact, the scientists have demonstrated for the first time a strange phenomenon known as the dynamical Casimir effect, or DCE for short.

The DCE involves stimulating the vacuum to shed some of the myriad “virtual” particles that fleet in and out of existence, making them real and detectable. Moreover, the real photons produced by the DCE in their experiment collectively retain a peculiar quantum signature that ordinary light lacks.

The research, led by Chris Wilson of Chalmers University of Technology in Sweden, shows that a related dynamic effect can occur when such a mirror moves very fast through the vacuum. The DCE was predicted over 40 years ago, but had not yet been observed experimentally due to the difficulty of creating the required experimental conditions.

“The DCE was conceived as a kind of thought experiment, sort of like Schrodinger’s Cat. According to quantum theory, if one could accelerate a mirror very quickly to near the speed of light, the mirror would radiate light as some of the mirror’s motional energy is imparted to virtual photons lurking in the vacuum, converting them into real photons.

“But it is practically impossible to accelerate a massive mirror to such high velocities. The required accelerations would be greater than the kind of shocks found in supernova or nuclear weapons explosions,” said team member Prof Tim Duty.

Instead, the scientists set out to demonstrate the DCE using microwaves, like those used for mobile phone and wireless communication signals. And instead of a massive mirror, they used a tiny microcircuit called a Superconducting Quantum Interference Device, or SQUID.

A newly discovered planet about 600 light years from our little rock has scientists around the world in a spin, with many heralding it as the best chance yet of containing alien life.

The find, announced early last week by NASA, was uncovered by the US space agency’s Kepler spacecraft, launched on a planet-hunting mission in 2009.

The planet, Kepler-22b, is 2.4 times bigger than Earth, orbits a star slightly smaller than our sun and has an average temperature of 22C. It is also closer to its sun-like star, giving it a “year” of 290 days.

What makes this discovery so exciting is that it is the smallest planet right in the middle of what has been dubbed the Goldilocks zone, where it’s not too hot and not too cold to either boil or freeze water, vital for life as we know it.

“It’s very exciting,” said University of Sydney astronomer Dennis Stello, who works on the Kepler project. “This is the first time we have actually found such a small planet in the habitable zone.”

I kid you not, some of the geniuses at Google are working on an elevator to space, as reported by Clare Cain Miller and Nick Bilton for the New York Times:

In a top-secret lab in an undisclosed Bay Area location where robots run free, the future is being imagined.

It’s a place where your refrigerator could be connected to the Internet, so it could order groceries when they ran low. Your dinner plate could post to a social network what you’re eating. Your robot could go to the office while you stay home in your pajamas. And you could, perhaps, take an elevator to outer space.

These are just a few of the dreams being chased at Google X, the clandestine lab where Google is tackling a list of 100 shoot-for-the-stars ideas. In interviews, a dozen people discussed the list; some work at the lab or elsewhere at Google, and some have been briefed on the project. But none would speak for attribution because Google is so secretive about the effort that many employees do not even know the lab exists.

Although most of the ideas on the list are in the conceptual stage, nowhere near reality, two people briefed on the project said one product would be released by the end of the year, although they would not say what it was…

Google may turn one of the ideas — the driverless cars that it unleashed on California’s roads last year — into a new business. Unimpressed by the innovative spirit of Detroit automakers, Google now is considering manufacturing them in the United States, said a person briefed on the effort.

Google could sell navigation or information technology for the cars, and theoretically could show location-based ads to passengers as they zoom by local businesses while playing Angry Birds in the driver’s seat.

Robots figure prominently in many of the ideas…

The biggest event which never happened and no one knows about? Offering a novel reinterpretation of some forgotten historical data, several Mexican researchers say a billion-ton comet may have passed a few hundred miles from Earth in 1883. Via Technology Review:

On 12th and 13th August 1883, an astronomer at a small observatory in Zacatecas in Mexico made an extraordinary observation. José Bonilla counted some 450 objects, each surrounded by a kind of mist, passing across the face of the Sun.

Bonilla published his account of this event in a French journal called L’Astronomie in 1886. Today, Hector Manterola at the National Autonomous University of Mexico in Mexico City, and a couple of pals, think that Bonilla must have been seeing fragments of a comet that had recently broken up. This explains the ‘misty’ appearance of the pieces and why they were so close together.

But there’s much more that Manterola and co have deduced. They point out that nobody else on the planet seems to have seen this comet passing in front of the Sun, even though the nearest observatories in those days were just a few hundred kilometers away.

That can be explained using parallax. If the fragments were close to Earth, parallax would have ensured that they would not have been in line with the Sun even for observers nearby. And since Mexico is at the same latitude as the Sahara, northern India and south-east Asia, it’s not hard to imagine that nobody else was looking.

Manterola and pals have used this to place limits on how close the fragments must have been: between 600 km and 8000 km of Earth. That’s just a hair’s breadth.

What’s more, Manterola and co estimate that these objects must have ranged in size from 50 to 800 metres across and that the parent comet must originally have tipped the scales at a billion tons or more, that’s huge, approaching the size of Halley’s comet.

One puzzle is why nobody else saw this comet. It must have been particularly dull to have escaped observation before and after its close approach. However, Manterola and co suggest that it may have been a comet called Pons-Brooks seen that same year by American astronomers.

Manterola and co end their paper by spelling out just how close Earth may have come to catastrophe that day. They point out that Bonilla observed these objects for about three and a half hours over two days. This implies an average of 131 objects per hour and a total of 3275 objects in the time between observations.

Each fragment was at least as big as the one thought to have hit Tunguska. Manterola and co end with this: “So if they had collided with Earth we would have had 3275 Tunguska events in two days, probably an extinction event.”

Visible cities, countries and landmarks include (in order) Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Francisco, Los Angeles. Phoenix. Multiple cities in Texas, New Mexico and Mexico. Mexico City, the Gulf of Mexico, the Yucatan Peninsula, El Salvador, Lightning in the Pacific Ocean, Guatemala, Panama, Columbia, Ecuador, Peru, Chile, Lake Titicaca, and the Amazon. Also visible is the earths ionosphere (thin yellow line), a satellite (55sec) and the stars of our galaxy.

The $750 million (£468 million) Upper Atmosphere Research Satellite (UARS) satellite, launched 20 years ago to study climate change, is set to breach the atmosphere within weeks.

In a new alert issued this week, officials warned pieces could land in densely populated areas on six continents including parts of Britain, Europe, North and South America and Asia.

Nasa claimed the risk to public safety from the “dead” satellite — which is orbiting just over 155 miles above the earth with an inclination of 57 degrees — was “extremely small”.

But senior space agency officials admitted they were “concerned” about the risk to billions of people when it starts falling uncontrolled out of orbit at any stage from later this month.

NASA admitted more than half a tonne of metal from the satellite, which ran out of fuel in 2005, will survive as the majority of it will burn up after entering Earth’s atmosphere.

Scientists in the US have warned NASA that the amount of so-called space junk orbiting Earth is at tipping point. A report by the National Research Council says the debris could cause fatal leaks in spaceships or destroy valuable satellites.

It calls for international regulations to limit the junk and more research into the possible use of launching large magnetic nets or giant umbrellas. The debris includes clouds of minuscule fragments, old boosters and satellites.

Some computer models show the amount of orbital rubbish “has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures,” the research council said in a statement on Thursday.

Apologies to anyone whose bubble will burst, but “Apollo 18,” the film opening Friday (Sept. 2), is fictional.

The film, purporting to be produced from footage kept secret by NASA and leaked to the media, chronicles a NASA mission to the moon that went awry when astronauts encountered signs of alien life there.

Whether because the studio actually believes anyone will be fooled or simply because it makes for a fun marketing angle, the Weinstein Co., which produced the picture, is calling it a “documentary.”

“Decades-old found footage from NASA’s abandoned Apollo 18 mission, where two American astronauts were sent on a secret expedition, reveals the reason the U.S. has never returned to the moon,” reads the movie’s official tagline.

The premise does begin in fact. NASA originally planned an Apollo 18 mission to the moon (along with Apollo 19 and 20), but those flights were canceled in 1970 due to budgetary constraints. The last NASA mission to the moon was Apollo 17, in December 1972.

The studio has been pushing the “reality” aspect of the film, going so far as to offer up a “famous scientist and researcher of UFO phenomena,” Stanton Friedman, for interviews.

“People ask why was there no Apollo 18 mission,” Friedman said in press materials. “I ask, what happened to Apollo 18 and Apollo 19? They were both paid for and astronauts were trained. What happened to these missions?”

Friedman hasn’t been allowed to view the film yet, according to the Los Angeles Times, but said he’s open to the possibility that the Apollo 18 mission did occur and that NASA’s been covering it up.

“One of the things the secret keepers take advantage of is ego,” Friedman told the L.A. Times. “I’m not saying that this footage exists. I’m saying it’s possible that there’s a whole classified side to this and that it would make sense. I allow for that possibility.”…

Alpha Centauri or bust.

The government agency that helped invent the Internet now wants to do the same for travel to the stars.

In what is perhaps the ultimate startup opportunity, Darpa, the Defense Advanced Research Projects Agency, plans to award some lucky, ambitious and star-struck organization roughly $500,000 in seed money to begin studying what it would take — organizationally, technically, sociologically and ethically — to send humans to another star, a challenge of such magnitude that the study alone could take a hundred years.

The awarding of that grant, on Nov. 11 — 11/11/11 — is planned as the culmination of a yearlong Darpa-NASA effort called the 100-Year Starship Study, which started quietly last winter and will include a three-day public symposium in Orlando, Fla., on Sept. 30 on the whys and wherefores of interstellar travel. The agenda ranges far beyond rocket technology to include such topics as legal, social and economic considerations of interstellar migration, philosophical and religious concerns, where to go and — perhaps most important — how to inspire the public to support this very expensive vision.

The Darpa plan has generated buzz as well as befuddlement in the labs, pubs, diners and Web sites that ring NASA centers both physically and virtually, where the dream of space travel has never died and where a few stubborn bands of scientists and engineers, fueled by science fiction dreams and prophecies, are designing spacecraft that could cross interstellar space, incubating a technology and preserving it for the day when it will be used.

“If you want to have a hobby, why can’t it be designing an interstellar spacecraft?” said Andreas Tziolas, who teaches at the University of Alaska and directs Project Icarus, a worldwide volunteer effort to design a spacecraft that could carry a scientific probe to a nearby star — perhaps Alpha Centauri, 4.4 light-years from here — in a trip that would take less than 100 years…

Russia yesterday announced plans for a hotel in orbit 217 miles up which would house seven guests in four cabins and have huge windows for views of the Earth turning below.

Just getting there will be an adventure in itself – it will take two days aboard a Soyuz rocket – and it won’t exactly be a budget holiday: A five day stay will cost you £100,000, on top of £500,000 for your journey.

The hotel, or the Commercial Space  Station to give it its proper name, is due to open by 2016 and, according to those behind it, will be ‘far more comfortable’ than the International Space Station used by astronauts and cosmonauts.

In the weightlessness of space, visitors can choose to have beds that are either vertical or horizontal, while showers will be sealed affairs to stop water going where it shouldn’t (those aboard the International Space Station must make do with sponge baths until they return home).

Citizens of the world: You are awesome. This week the SETI (Search for Extraterrestrial Intelligence) Institute announced that it had raised more than $200,000 from a crowd-sourced fundraising effort that launched this spring. The money, which came from just over 2,000 people who want to keep the search for alien life alive, will help the institute put its Allen Telescope Array back online.

“We are so grateful to our donors,” said Tom Pierson, who co-founded the SETI Institute with Jill Tarter (the inspiration for Jodie Foster’s character in “Contact”). “We believe we will be back on the air in September.”

On the Setistars website, where the call for donations was originally placed, large red type proclaims: “Thank You for Your Support to Resume the Search!”

The Allen Telescope Array, or ATA, is a series of 42 linked radio-telescope dishes funded by a $30-million gift from Microsoft Corp. co-founder Paul Allen. Built at the Hat Creek Radio Observatory in a valley near Mt. Shasta, it is the first group of radio telescopes built from the ground up with the intention of monitoring the universe full-time for radio waves that would indicate there is life on other planets.

The ATA has been monitoring the universe consistently since 2008, but in April, SETI and its partner, the Radio Astronomy Lab of UC Berkeley, ran out of money and had to put the ATA into hibernation mode.

That’s when SETI turned to earthlings via the Internet, to see if they could help raise money to put the array back online.

So far, 2,276 of them have responded and the institute met its fundraising goal with days to spare. (Pierson notes that the institute is happy to collect additional donations.)

A giant quasar billions of light-years away is surrounded by water vapor that could fill Earth’s oceans over 140 trillion times. Via National Geographic:

In a galaxy 12 billion light-years away resides the most distant and most massive cloud of water yet seen in the universe, astronomers say.

Weighing in at 40 billion times the mass of Earth, the giant cloud of mist swaddles a type of actively feeding supermassive black hole known as a quasar.

Among the brightest and most energetic objects in the universe, quasars are black holes at the centers of galaxies that are gravitationally consuming surrounding disks of material while burping back out powerful energy jets.

“As this disk of material is consumed by the central black hole, it releases energy in the form of x-ray and infrared radiation, which in turn can heat the surrounding material, resulting in the observed water vapor,” said study co-author Eric Murphy, an astronomer with the Carnegie Observatories in Pasadena, California.

Sometimes asteroids come very close to home, about every six years. The latest asteroid to come closer to Earth than our own satellites appears today. Via Space.com:

An asteroid the size of a tour bus will fly past Earth today (June 27) so closely it will be beneath some of the planet’s satellites.

The rock, named asteroid 2011 MD will zoom by just 7,500 miles (12,000 km) above the planet, making a sharp turn forced by Earth’s gravity before winging off into space again. The flyby will occur at about 1 p.m. EDT (1700 GMT).

There is no risk of an impact, NASA scientists said. The space rock, estimated to be between 29 to 98 feet (9 to 30 meters) wide, is likely too small to survive a plunge through our atmosphere anyway. An asteroid this size, if it were mostly stony, would break apart and burn up before hitting the surface. Iron-heavy space rocks are better at surviving the fiery entry, however.

Either way, calculations show that asteroid 2011 MD will make a dogleg shift in its trajectory and scoot on by.

The argument that life on Earth may have been seeded from the stars just received a major boost, as scientists have found the building blocks of life inside a meteorite that landed in British Columbia in 2000.

The Tagish Lake meteorite landed in January of that year, a streaking fireball that burst into more than 500 fragments which rained down on the lake. In its trip from the outer reaches of the asteroid belt it burned down from 56 tonnes to 1.3, and deep inside the fragments there are the basic building blocks of life, including the amino acids, sugars and hydrocarbons that could have jump started life on our planet.

This meteorite is the only uncontaminated example we’ve ever found, thanks to the quick actions of the people who spotted it. What the researchers have found is that the organic compounds in the rock date back to the early days of the solar system, or possible predate it. A large parent body was formed in orbit around the star with chunks of ice trapped within. Over the billions of years that followed, the ice warmed, and the hydrothermal change altered the organic compounds. The large body has since broken up, and constitutes the carbonaceous chondrites meteorites that make their way to Earth. Within the samples discovered was organic matter that had properties that spanned properties found in other similar meteorites around the world — showing that the differing organic compound makeup of these rocks can come from a common precursor.

A digital image of the newly theorized 'foam zone'.

Is our solar system a ‘cosmic jacuzzi filled with magnetic bubbles’? The outer shield of our solar system was thought to be smooth, like soda gone flat, but new theory believes it may foam-like filled with “bubbles.” From National Geographic:

The edge of the solar system may be a frothy sea of giant magnetic “bubbles,” a new NASA study says.

The new findings may mean that our system’s magnetic barrier—once thought to be a smooth shield—may be letting in more harmful cosmic rays and energetic particles than previously thought.

The new “foam zone” theory is based on a computer model created using data from NASA’s twin Voyager spacecraft, both launched in 1977 and currently about 10 billion miles (16 billion kilometers) from Earth.

In 2007 Voyager 1 recorded dramatic dips and rises in the amount of electrons it encountered as the craft traveled through the heliosphere—the “force field” that surrounds the entire solar system and is created by the sun’s magnetic field. Voyager 2 made similar observations of these charged particles in 2008.

A NASA computer model suggests the electron readings make sense if it’s assumed the spacecraft were entering and exiting magnetic bubbles lining the edges of the heliosphere.

Montage of Jupiter and the Galilean satellites, Io, Europa, Ganymede, and Callisto.

When we look up at the night sky we see millions of  twinkling stars. But how many planets are we not seeing? Astronomers’ new study has found that ‘Jupiter-like gas giants’ are more common than previously thought. The National Geographic reports:

If you look to the stars tonight, consider this: No matter how innumerable they may seem, there are far more planets than stars lurking out there in the darkness, a new study suggests.

The study uncovered a whole new class of worlds: Jupiter-like gas giants that have escaped the gravitational bonds of their parent stars and are freely roaming space.

What’s more, “our results indicate that such planets are quite common,” said study team member David Bennett, an astronomer at Notre Dame University in Indiana.

“There’s a good chance that the closest free-floating planet is closer to Earth than the closest star.”

Ohio State University astronomer Scott Gaudi added, “It’s not surprising that free-floating planets are out there”—they’ve been predicted by planet-formation theories for years—”it’s just how many of them that they’re finding.”

A woman who tried to sell what she said was a rare piece of moon rock for $1.7 million was detained when her would-be buyer turned out to be an undercover NASA agent, officials said Friday.

The gray rocks, which are considered national treasures and are illegal to sell, were given to each U.S. state and 136 countries by then-President Richard Nixon after U.S. moon missions and can sell for millions of dollars on the black market.

NASA investigators and Riverside County sheriff’s deputies detained the woman after she met Thursday with an undercover NASA investigator at a restaurant in Lake Elsinore, about 70 miles southeast of Los Angeles, the sheriff’s office said. The investigation was conducted over several months.

NASA planned to conduct tests to determine whether the rock came from the moon as the woman claimed. “We don’t know if it’s lunar material,” said Gail Robinson, deputy inspector general at the space agency.

The CIA created Area 51 in 1955 to test and develop top secret U.S. military projects in the remote Nevada desert. More than 50 years later, the base still doesn’t officially exist and appears on no public U.S. government maps.

In the 1950s and ’60s, Area 51 was the epicenter of the OXCART project, intended to create the successor for the U-2 spy plane.

The OXCART plane was expected to be undetectable in the air as it flew surveillance and information-gathering missions over the Soviet Union. But Area 51 personnel soon found it necessary to conceal the craft from the Soviets eyes even when it was still being tested on the ground.

It was discovered that Soviet spy satellites, dubbed ash cans by Area 51 staff, were making regular rounds over Nevada.

A new survey is under way to search for signs of intelligent extraterrestrial life, but this one has a twist: Instead of listening for alien signals from anywhere in the sky, scientists are aiming radio telescopes at the alien planets most likely to be like our own Earth.

The new search, which began last week, is scanning 86 alien worlds for radio signals that could suggest the presence of an advanced civilization. The extrasolar planets are thought to be the most Earth-like of the 1,235 candidate planets discovered so far by NASA’s prolific Kepler space observatory.

“We’ve picked out the planets with nice temperatures — between zero and 100 degrees Celsius [32 and 212 degrees Fahrenheit] — because they are a lot more likely to harbor life,” said physicist Dan Werthimer of the University of California, Berkeley, in a statement.

This new SETI search is not part of the SETI Institute, which has long served as the Earth’s ears for any signals from intelligent aliens. Earlier this month, the Institute announced it was placing its primary listening station – a network of radio telescopes called the Allen Array — in hibernation due to funding problems.

Some planets are just flipping backward.

Of the more than 500 planets detected around stars besides our Sun, the vast majority appear to spin the same way the star does, scientists reported on Wednesday in the journal Nature.

But some of these extrasolar planets spin in the opposite direction of the stars they orbit, astronomers found. These strange, backward-spinning planets are usually gassy giants called hot Jupiters, not rocky orbs like Earth.

Besides their backwards twirling, which the astronomers call flipped orbits, these big planets huddle close to their stars, unlike Jupiter, which is about 483 million miles (778 million km) from the Sun, more than five times as distant from the Sun as Earth.

“That’s really weird, and it’s even weirder because the planet is so close to the star,” Frederic Rasio of Northwestern University said in a statement.

“How can one be spinning one way and the other orbiting exactly the other way? It’s crazy. It so obviously violates our most basic picture of planet and star formation.”…

Private US company SpaceX hopes to put an astronaut on Mars within 10 to 20 years, the head of the firm said.

“We’ll probably put a first man in space in about three years,” Elon Musk told the Wall Street Journal Saturday. “We’re going all the way to Mars, I think… best case 10 years, worst case 15 to 20 years.”

SpaceX is one of the two leading private space companies in the United States and has won $75 million from the US space agency NASA to help its pursuit of developing a spacecraft to replace the space shuttle.

The California-based company last year completed its first successful test of an unmanned space capsule into orbit and back.
