What did NASA's planet-hunting Kepler mission find now? Find out when you watch a NASA news briefing live, right here.
At 11 a.m. Pacific time, NASA will host a news briefing detailing the latest discoveries from the agency's Kepler Space Telescope, and we'll be streaming the press conference live.
The telescope has been scanning the skies for nearly four years, looking for planets where liquid water -- and possibly life -- might exist.

The ultimate goal of the mission is to find "Goldilocks planets" where it is neither too hot nor too cold, but just right for life to take hold.
You'll find live streaming video of the conference below.
