The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...

A new classification scheme may help us better understand planet formation — including the history of our own family of worlds.

Carbon dioxide has been detected on a planet outside our solar system for the first time. The gas has been observed directly by the James Webb Space Telescope on four exoplanets, all belonging to ...

The Kuiper Belt is a region in space beyond the orbit of Neptune that's home to Pluto and most of the known dwarf planets, as well as some comets that are thought to be relics of the solar system ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...

Once they are all in place, seven of the eight planets in our solar system will grace our sky. For much of the week, six of the planets may be visible, according to NASA. On Friday, however ...

Using advanced simulations, the researchers propose that these planets emerge from distinct rings of planetesimals, providing fresh insight into planetary evolution beyond our solar system.

NASA's James Webb Space Telescope was recently used to capture direct images of four Saturn-like exoplanets in a solar system 130 light-years away.
