The Kepler Spacecraft was launched in 2009 with the specific aim of locating exoplanets. That is, planets with similar attributes to Earth and a safe enough distance from a parent star to sustain life.
When it's not snapping the first ever pictures of Pluto or scouring Mars for skeletons and pyramids, NASA is exploring the depths of space for life-supporting planets.
Now the space agency has put out a statement saying it will hold a press conference to reveal: "new discoveries made by its planet-hunting mission, the Kepler Space Telescope".
The announcement will take place at 4pm on Thursday, July 23 and could involve the discovering of a second Earth that potentially supports life.
