Earth's final sunset predicted

USA Today - Feb 26, 2008
"Some say the world will end in fire, Some say in ice," wrote the poet Robert Frost. Astronomers, it turns out, are in the former camp.

A new calculation predicts that Earth will be swallowed up by the sun in 7.6 billion years, capping off a longstanding debate over whether the sun's gravitational pull will have weakened enough for Earth to escape final destruction or not.

Other theorists have predicted that our planet will fry as the sun expands in its old age. But the time estimates have varied by a couple billion years.

"Although people have looked at these problems before, we would claim this is the best attempt that's been made to date, and probably the most reliable," said astronomer Robert Smith, emeritus reader at the U.K.'s University of Sussex, who made the new calculations with astronomer Klaus-Peter Schroeder of the University of Guanajuato in Mexico. "What we've done is to refine existing models and to put the best calculations we can at each point in the model."

If 7.6 billion years doesn't sound like an urgent death sentence, don't relax yet. Regardless of whether Earth will ultimately be vaporized, as the sun heats up, our planet will become too hot to live on before then.

Solar Cycle 24 Has Started

"Solar physicists have been waiting for the appearance of a reversed-polarity sunspot to signal the start of the next solar cycle. As of Friday, that wait is over. A magnetically reversed, high-latitude sunspot emerged on the surface of the sun. Just a few months ago, an 'All Quiet Alert' had been issued for the sun. This reversed-polarity sunspot marks the beginning of the sun's return back to Solar Maximum. Solar Cycle 24 has been the subject of much speculation due to competing forecasts on whether it will be a highly active or a quiet low cycle. If it is a low cycle, it may very well be a test of validity for some CO2 based global warming theories. Only time will tell."

The auroras are dancing over Scandinavia. Hanneke Luijting of Tromso, Norway, sends this report: "Last night, we had to drive slowly behind a family of moose (who preferred to jog right in the middle of the road instead of going left or right) to get these images. It was an incredible show!" Here is the view recorded by his Canon 350D:

“Radiation Belt Remediation” Plan Could Affect HF Propagation, Study Suggests

NEWINGTON, CT, Aug 15, 2006 -- A New Zealand university research group believes a US Defense Advanced Research Projects Agency (DARPA) “Radiation Belt Remediation” (RBR) plan could cause major worldwide disruptions to HF radio communication and GPS navigation. DARPA reportedly envisions the (RBR) system as a way to protect low-Earth orbiting (LEO) satellites from damage caused by severe solar storms or even from high-altitude nuclear detonations. The New Zealand-based research group suggests, however, that policymakers need to carefully consider the implications of the project. Headed by Otago Physics Department researcher Craig Rodger, the research group says RBR could significantly affect radio propagation from several days to a week or longer.

“We’ve calculated that Earth’s upper atmosphere would be dramatically affected by such a system, causing unusually intense HF blackouts around most of the world,” Rodger said in an Otego University news release. “Airplane pilots and ships would lose radio contact, and some Pacific Island nations could be isolated for as long as six to seven days, depending on the system’s design and how it was operated.” GPS would likely also be disrupted on a large scale, he added.

Reversing Magnetic Poles Observed in Another Star

News out of the University of Hawaii Institute for Astronomy that for the first time, a magnetic pole reversal has been observed in a star other than our own. Tau Bootis, while similar to the Sun, also has a planet more than six times larger than Jupiter orbiting at only a twentieth of the distance between Earth and the Sun. Scientists hope to use this discovery to learn more about the magnetic dynamics in the Sun, which can affect our telecommunications, among other things.

Is our cosmos teeming with alien 'unmatter'?

Scientists could have overlooked a new kind of "stuff," reports Roger Highfield

A radical new proposal to explain one of the enduring mysteries of the universe says we are bathed in an entirely new kind of matter, consisting of "unparticles."

  • Cosmic snapshot of dark energy enigma
  • Cosmology study may shed new light on dark matter
  • Astronomers find evidence of 'dark matter'
  • The suggestion that the universe contains a novel kind of "stuff" offers a remarkable way to solve the puzzle of dark matter, which has perplexed cosmologists since it was discovered more than 70 years ago.
