NASA said Monday it will soon announce a major discovery regarding planets that orbit other stars.

The agency will make the out-of-this-world announcement about a “discovery beyond our solar system” at a press conference at 1 p.m. Wednesday.

The space agency will “present new findings on planets that orbit stars other than our sun, known as exoplanets,” NASA said.

The announcement has the astronomy community abuzz that NASA is set to announce its best finding thus far that a planet outside our solar system could potentially support life.

Astronomers and planetary scientists from across the world will be at the press conference, the paper reported.

Italy’s 3.6-meter (12-foot) Galileo National Telescope revealed the closest known rocky planet, HD 219134b, which is 21 light-years from Earth, in 2015.

But the planet orbits its star too closely for life to be possible.
