Very Superstitious

MUMBAI, India — Indian astrologers are predicting violence and turmoil across the world as a result of this week's total solar eclipse, which the superstitious and religious view as a sign of potential doom.
But astronomers, scientists and secularists are trying to play down claims of evil portent in connection with Wednesday's natural spectacle, when the moon will come between the Earth and the sun, completely obscuring the sun.
In Hindu mythology, the two demons Rahu and Ketu are said to "swallow" the sun during eclipses, snuffing out its life-giving light and causing food to become inedible and water undrinkable.

Another World

A group of astronomers announced the discovery of the least massive planet yet detected outside of our solar system. It is lightweight enough--between two and three times the mass of Earth--to almost certainly be rocky like Earth rather than a huge ball of gas. Although the planet orbits too close to its star to be habitable, a new analysis of one of its neighbors suggests a world with deep oceans. All this raises the prospect of discovering an Earth-size planet orbiting at just the right distance from its star to give life a chance.
First discovered in 2007, Gliese 581d was originally calculated to be too far away from its host star—and therefore too cold—to support an ocean. But that has all changed.

Armageddon's Near Miss

Sky-watchers in Asia, Australia, and the Pacific islands welcomed a surprise guest Monday: an asteroid that passed just 41,010 miles (66,000 kilometers) above Earth.
Discovered only days ago, asteroid 2009 DD45 zipped between our planet and the moon at 13:44 universal time (8:44 a.m. ET). The asteroid was moving at about 12 miles (20 kilometers) a second when it was closest to Earth.
