Perseids Meteor Shower

Space Weather News for August 12, 2010
http://spaceweather.com

PERSEID METEOR SHOWER: The annual Perseid meteor shower is underway. Earth is passing through a wide stream of debris from Comet Swift-Tuttle, and each time a fleck of comet dust hits Earth's atmosphere--flash!--there is a meteor. Forecasters say the shower will peak on Thursday, August 12th, and Friday, August 13th. You can see Perseids flitting across the sky at any time between about 10 pm on Thursday evening and sunrise on Friday morning. Observers who get away from city lights can expect to count dozens of meteors per hour, especially during the dark hours before dawn.

Tune into http://spaceweather.com for full coverage of the shower, including a live meteor radar, a "fireball cam," updated meteor counts and pictures from around the world.

BONUS: If you go outside a little early on Thursday evening, around sunset, you'll see a beautiful gathering of planets in the sunset sky--Venus, Mars, Saturn and the crescent Moon. It's a nice way to start a meteor watch. Sky maps may be found at http://spaceweather.com.

Mankind must abandon earth or face extinction: Hawking

Mankind's only chance of long-term survival lies in colonising space, as humans drain Earth of resources and face a terrifying array of new threats, warned British scientist Stephen Hawking on Monday.

"The human race shouldn't have all its eggs in one basket, or on one planet," the renowned astrophysicist told the website Big Think, a forum which airs ideas on many subjects from experts.

"Our only chance of long-term survival is not to remain inward looking on planet Earth, but to spread out into space," he added.

He warned that the human race was likely to face an increased number of events that threaten its very existence, as the Cuban missile crisis did in 1962.

The Cold War showdown saw the United States and Soviet Union in a confrontation over Soviet missiles deployed in Cuba, near US shores, and brought the world to the brink of nuclear war.

"We are entering an increasingly dangerous period of our history," said Hawking.

"Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill."

If we want to survive beyond the next century, "our future is in space," added the scientist.

"That is why I'm in favour of manned, or should I say 'personed', space flight."

His comments came after he warned in a recent television series that mankind should avoid contact with aliens at all costs, as the consequences could be devastating.
