During the first mission, a star explorer spotted two Jupiter-sized planetsIn a remote corner
European spacecraftagency (ESA) can see bright objects in the distance, but has now been redesigned to study the motion of planets through its parent star. Researchers have used artificial intelligence (AI) to scour the spacecraft's archive looking for characteristic dips in light that occur when a planet temporarily eclipses a star.
"The discovery of two new planets was made inthe result of precise searches using artificial intelligence methods,” said co-author Shay Zucker, head of the School of Environment and Geosciences at Tel Aviv University.

Zucker added that there are other candidates,which they want to study with Gaia. Now they have 40 planets, which they also discovered recently. Now the astronomical community will have to try to confirm their planetary nature.
Two new planets named Gaia-1b andGaia-2b are "hot Jupiters" because the gas giants orbit very close to their host stars. According to the researchers, each of them makes a revolution around the star in just four days.
Confirmed planets and dozens of alleged onesindicate that Gaia's ability to observe celestial bodies is much wider than previously thought. Despite its precise ability to chart the movement of stars and their changing brightness, the detection of much smaller and fainter planets has so far been in doubt.
