The Artemis II mission, which took four US astronauts around the Moon and to a record-breaking distance from Earth, was a ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

Using the James Webb Space Telescope, astronomers have investigated the giant exoplanet 29 Cygni b — work that could clarify ...

A giant planet in the HR 8799 system orbits six times faster than its neighbor, reigniting the mystery surrounding its origin ...

The JWST discovers an impossible anomaly on TOI-5205 b and challenges everything we thought we knew about giant planets.

For the first time, astronomers have successfully observed a planet in the midst of its formation, a groundbreaking achievement that provides invaluable insights into the processes that shape ...

An exoplanet, TOI-5205 b, which is almost as large as Jupiter, orbits a small red star. By many estimates, this red star ...

The astro-modified camera used to take this photo lets in the hydrogen alpha light that is normally filtered out. This modification makes the camera more sensitive to the red end of the ...

A strange “forbidden” planet spotted by the James Webb Space Telescope is turning planetary science on its head. TOI-5205 b, a Jupiter-sized world orbiting a small, cool star, has an atmosphere ...

Earth may have won a cosmic chemistry lottery. Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, ...
