Neptune harbors cosmic secrets, in part because of its distance from Earth. But researchers have just unlocked one of the planet's mysteries by using the unique capabilities of the James Webb Space ...

Despite being part of our own solar system, Neptune has long been a cosmic mystery. It's the most distant planet from the Sun and also one of the least explored. Only one spacecraft—Voyager 2—has ever ...

Neptune, the most distant major planet in the Solar System, has finally given up one of its longest held secrets. After decades of hints and near misses, astronomers now have crisp, direct views of ...

Astronomers have characterized the atmosphere of a young (20 Myr old) transiting exoplanet and found it to be unusually clear and puffy. By analyzing the planet's atmospheric features, they were able ...

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 star ...

It only took some 417 years since the invention (if going by patent filings) of the telescope to finally see Neptune's auroras, and it's thanks to NASA's James Webb Space Telescope, or JWST (the same ...

NASA's James Webb Space Telescope has peeled back the layers on sub-Neptunes, a type of gassy exoplanet scattered in large numbers throughout the universe. While sub-Neptunes' thick atmospheres have ...

Unlike the James Webb Space Telescope's views of other sub-Neptune exoplanets' atmospheres, its look at TOI-421 b was clear. Credit: NASA / ESA / CSA / Dani Player illustration A sweltering planet ...
