Kepler Telescope Studies Superflares
The Kepler space telescope has provided fresh insight on the colossal explosions that can afflict some stars. These enormous releases of magnetic energy--known as superflares--could damage the atmosphere of a nearby orbiting planet, putting at risk any lifeforms that might reside there.
Astronomers are searching for unseen moons around the planets that the Kepler mission's scientists have discovered. Researchers report that in their quest they have unexpectedly detected a hidden planet--and probably two--by using a technique that promises to aid the search for smaller planets much like Earth.
Researchers have now solidified Vesta's reputation as an archetype for understanding planetary evolution. Dawn, which began orbiting Vesta last July and lowered itself to within 200 kilometres of the asteroid over the following months, has gathered strong evidence that Vesta is indeed the source of the 'Vestoid' family of asteroids as well as the howardite-eucrite-diogenite meteorite family, which accounts for 6% of meteorites.
One of the least expected successes in London's West End last week was Stella by the Take the Space theatre company. The show was about female astronomers--notably the tiny, forgotten, angry Caroline Herschel.

PODCASTS: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
