A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is ...

Observations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real ...

The discovery of new planets is always thrilling. This time, scientists have found an unusual planet orbiting a nearby star.

Neptunes, which are exoplanets whose size is between Earth and Neptune, teach astronomers about exoplanet formation and evolution? This is wha | Space ...

Scientists have discovered a sub-Neptune exoplanet, GI 410 b, using the radial velocity technique. It orbits a nearby star 39 light years from Earth and has a mass 8.5 times that of our planet. The ...

Imagine a Slushee™ composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted slushballs, dubbed "mushballs ...

In late 2017, a mysterious object tore through our solar system at breakneck speed. Astronomers scrambled to observe the fast ...

Jupiter experiences a unique weather phenomenon where mushballs, ice-encrusted slushballs of ammonia and water, rain down like hailstones.

A Southwest Research Institute-led study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in ...

A group of comets with unexplained movements presents a quandary D avide Farnocchia hunts down and tracks asteroids, and several years ago he saw something he couldn’t explain. Farnocchia works at ...
