Some methods almost sound like science fiction: Using gravity as a magnifying glass, watching stars wobble at turtle-like speeds, and searching for tiny dips in starlight.
WFIRST, NASA's Wide Field Infrared Survey Telescope, is the next step in our hunt for Earth-sized exoplanets.

Dawn is maintaining its smooth and steady course through the solar system as it gradually closes in on Vesta.
• November 03, 2010
Continuing its journey to collect treats in the main asteroid belt, Dawn is making excellent progress toward its July 2011 rendezvous with protoplanet Vesta.
• September 28, 2010
On the third anniversary of traveling through the solar system on its own since dispatching Dawn on a separate journey, Earth continues to orbit the sun in much the same way it has been.
• September 02, 2010
Dawn is now so far from the sun that even with its tremendous solar arrays, it does not receive enough sunlight to generate sufficient electrical power to operate all systems and still achieve maximum thrust.
• July 28, 2010
Dawn is flying smoothly through the asteroid belt, now less than a year from entering orbit around Vesta, the first of its two cosmic destinations.
• June 30, 2010
A new version of the Dawn spacecraft is continuing the ambitious journey through the asteroid belt to uncharted distant worlds.
• June 01, 2010
After more than 2.5 years of spaceflight, and more than 6 months in the asteroid belt, Dawn's interplanetary journey continues smoothly.
• May 02, 2010
Dawn remains on course and on schedule for its appointments with Vesta and Ceres, colossal protoplanets in the main asteroid belt.
