NASA is about to make a big reveal this upcoming week, and it reportedly has something to do with aliens. More specifically, scientists are using artificial intelligence to help the Kepler telescope track down new alien planets and they’ve just made a huge discovery.

The big announcement is unlikely to be that they’ve found alien life, for obvious reasons, but NASA has indeed called a teleconference for Thursday, Dec. 14 at 1 p.m. EST to announce the “latest Kepler discovery,” according to a Dec. 8 statement. AI fueled by machine learning from Google was reportedly a key part of this big discovery.

Everyone is talking about what this announcement could be, but we’ll have to wait until Thursday to find out what this find is, and how AI was involved. The Kepler space telescope has played a key role in recent years in finding exoplanets outside of our solar system that could represent other Earth-like places that could be home to alien life.

“When Kepler launched in March 2009, scientists didn’t know how common planets were beyond our solar system. Thanks to Kepler’s treasure trove of discoveries, astronomers now believe there may be at least one planet orbiting every star in the sky,” NASA said in a statement. “Kepler completed its prime mission in 2012 and went on to collect data for an additional year in an extended mission. In 2014, the spacecraft began a new extended mission called K2, which continues the search for planets outside our solar system, known as exoplanets, while introducing new research opportunities to study young stars, supernovae and other cosmic phenomena.”
