Benchmarks: February 4, 1962: Five planets align - but no end of the world

In the movie "2012," released in theaters last November, an alignment of five planets in our solar system — supposedly foretold by the Mayans thousands of years ago — causes horrors that span nearly every earth science disaster movie cliché: solar flares, neutrinos, earthquakes, volcanoes, floods, poles shifting, oceans washing over the tallest mountains in the world, cities falling into the sea, mass hysteria and, basically, total destruction of life as we know it.

Super-Earths: Mirrors of our world?

Fifty light-years from Earth, in the constellation Pegasus, burns a yellow star not unlike our sun. The star, called 51 Pegasi, was one of 142 stars under the watchful gaze of Swiss astronomers Michel Mayor and Didier Queloz of the University of Geneva in 1994. From the La Silla Observatory at the southern end of Chile’s vast Atacama Desert, Mayor and Queloz were tracking how these stars move in the sky, hoping to determine whether the stars were alone — or whether any of them might be accompanied by a planet or two.
