A $1.6 billion space telescope that could reveal the nature of dark energy and identify Earth-like planets should be the top priority for astronomers and astrophysicists, according to a long-awaited report that lays out the pressing needs for the next 10 years of space science.
The Wide-Field Infrared Survey Telescope (WFIRST) would launch in 2020 as one of the next generation of telescopes that should target the early universe, search for nearby habitable planets and test the boundaries of fundamental physics, according to the Astro2010 Decadal Survey by the National Academy of Sciences.
“During the last Decadal Survey, exoplanets weren’t a big element, and dark energy wasn’t really a big deal,” said Claire Max, an astronomer at the University of California in Santa Cruz and member of the Decadal Survey committee. “There are a whole lot of things that are really new.”

European astronomers said Tuesday that they had discovered the smallest planet yet found orbiting another star. The planet could be as little as only 1.9 times as massive as the Earth and belongs to a dim red star known as Gliese 581, which lies about 20 light-years from Earth in the constellation Libra.
