NASA has officially tracked 6,000 confirmed exoplanets—planets outside our solar system—a milestone that reflects decades of cumulative discoveries and ongoing research efforts. This achievement, ...

A planetary system 116 light-years from Earth has a peculiar pattern. It could flip the script on how planets form, scientists say.

The interstellar visitor may still have a few things to tell us before it leaves our solar system.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

How many planets outside our solar system, known as exoplanets, exist throughout the Milky Way Galaxy? While that might never be determined, NASA recently announced the total number of confirmed ...

When scientists discovered the first planet orbiting another star in 1995, few outside astronomy circles noticed. That planet, 51 Pegasi b, opened the door to a field that now boasts more than 5,000 ...

A newly identified planet candidate, HD 137010 b, looks strikingly Earth-like in size and orbit — but it may be colder than Mars due to its dimmer star. If it has a thick enough atmosphere, though, ...

Their observations of a faint, cool M-dwarf star called LHS 1903 revealed a system with a rocky world at its outer edge. LHS ...

A mysterious object has caused a long-lasting and extreme dimming of a distant star, but is this object a 'failed star' brown dwarf, or an exceptionally massive super-Jupiter exoplanet?

Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler ...
