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

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

The world of Sailor Moon does not just relate to our own solar system, but the many unknown planets from the original story ...

"We have been waiting for 10 years to confirm that our finely tuned operations of the telescope would also allow us to access the inner planets. Now the results are in, and we can do interesting ...

NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in HR 8799, a multiplanet system 130 light-years away that has long been a ...

The two exoplanets, or planets outside of our solar system, orbit a star called TOI ... meaning that for every three orbits of the inner planet, the outer planet completes almost exactly two.

All planets are made of gas, ice, rock and metal, and models of how planets form usually assume that these materials don't ...

Floating around at the edge of the Solar System are leftovers from its formation. This is the Kuiper Belt, which is composed of chunks of rock and ice like comets, dwarf planets, and random objects ...

This is particularly puzzling, as a vast majority of meteorites can be traced to some well-known parent body—whether that be ...

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.
