Solar Maximum Starts in 2011
The fearmongers wishing for something, anything, to happen in 2012 have seized on the next peak in the cyclical activity experienced by our sun. AFP reports that an upswing starts next year, but the climax will probably not be until 2013, rather than December 21, 2012:
The coming year will be an important one for space weather as the Sun pulls out of a trough of low activity and heads into a long-awaited and possibly destructive period of turbulence.
Many people may be surprised to learn that the Sun, rather than burn with faultless consistency, goes through moments of calm and tempest.
But two centuries of observing sunspots — dark, relatively cool marks on the solar face linked to mighty magnetic forces — have revealed that our star follows a roughly 11-year cycle of behaviour.
The latest cycle began in 1996 and for reasons which are unclear has taken longer than expected to end.
Now, though,…
Incoming! The Sun Unleashes A Massive CME at Earth (Video)
The most awesome part of this story from Ian O’Neill on Discovery News is the technology that even recognized this event in the first place, but there are some out there who fear-monger about it (needless to say the title of this story is in jest). I try to keep in mind that the universe is more a wondrous place, than one intent on destroying human life (I’m looking at you, Larry Joseph). Ian O’Neill writes on Discovery News:
Earlier this morning, NASA’s Solar Dynamics Observatory (SDO) witnessed a complex magnetic eruption on the sun. The joint NASA/ESA Solar and Heliospheric Observatory (SOHO) — a mission sitting at the L1 point between the Earth and the sun — also spotted a large coronal mass ejection (CME) blasting in the direction of Earth.
It is thought that the SDO and SOHO observations are connected, making this a global magnetic disturbance affecting the whole of the Earth-facing side of the sun.
Record Collapse of Earth’s Upper Atmosphere Puzzles Scientists
Space.com reports:
An upper layer of Earth’s atmosphere recently collapsed in an unexpectedly large contraction, the sheer size of which has scientists scratching their heads, NASA announced. The layer of gas — called the thermosphere — is now rebounding again. This type of collapse is not rare, but its magnitude shocked scientists.
“This is the biggest contraction of the thermosphere in at least 43 years,” said John Emmert of the Naval Research Lab, lead author of a paper announcing the finding in the June 19 issue of the journal Geophysical Research Letters. “It’s a Space Age record.”
The collapse occurred during a period of relative solar inactivity — called a solar minimum from 2008 to 2009. These minimums are known to cool and contract the thermosphere, however, the recent collapse was two to three times greater than low solar activity could explain.
“Something is going on that we do not understand,” Emmert said.
NASA Worried About Solar Threat To Earth?
One of the alarmist predictions for 2012 concerns the supposed cyclical climax of solar flare activity (see the Larry Joseph section in the disinformation documentary 2012: Science or Superstition). Although NASA felt moved to create a web page to deny this kind of story around the release date of Roland Emmerich’s 2012 disaster movie, apparently they are hedging their bets. Chris Hastings and Jonathan Leake report on a new NASA probe that could help scientists predict chaos-causing solar storms, in the Times:
NASA is to embark on one of its most ambitious missions in an attempt to unlock the secrets of the sun.
Following its launch in nine days’ time, the US space agency’s Solar Dynamics Observatory (SDO) will spend five years in orbit trying to discover the causes of extreme solar activity, such as sun spots and solar winds and flares.
Scientists have long been aware that disturbances on the sun can trigger…
Coast to Coast AM – Solar Cycles & Civilizations
Engineer and scientist Maurice Cotterell discussed his research into sun spots and solar cycles, and how they affect history, evolution, and the rise and fall of civilizations. The Chinese first observed sunspots 3,000 years ago, and were aware of their 11-year cycle, he said. Additionally, there are sun cycles lasting 187 years, and 18,000 years, Cotterell explained. Periods with higher sunspot activity lead to increased fertility but also disorders such as schizophrenia, whereas during the solar minimum there can be mini-ice ages, he detailed.
He theorized that creatures evolved through DNA mutations brought about by solar wind radiation…
