The first direct evidence for auroras on Neptune has been spotted by the James Webb Space Telescope (JWST) and the Hubble Space Telescope. Auroras happen when energetic particles from the Sun become ...

Some of these open clusters are pretty famous, such as the Pleiades cluster, also known as the Seven Sisters. This is ...

The Near-Infrared Spectrograph on the James Webb Space Telescope picked up cyan splotches of auroral activity, right, that could not be picked up by the Hubble, left, and other telescopes in the past.

NASA's James Webb Space Telescope (JWST) has found water swirling in the air of a distant alien planet, a new study reports. That exotic world is TOI-421 b, a boiling-hot "sub-Neptune" orbiting a ...

NAS's James Webb Space Telescope has captured Neptune’s glowing auroras in the best detail yet.

That exotic world is TOI-421 b, a boiling-hot "sub-Neptune" orbiting a star about 244 light-years from Earth whose atmosphere JWST recently probed in detail."One of the most exciting prospects in ...
