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 ...

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

A bold geochemical model reveals that TOI‑270 d, a sub‑Neptune 73 light‑years away, is likely a giant rocky world cloaked in ...

The exoplanet K2-18b could harbor a massive ocean, but scientists will need to study the planet more to see if it’s really ...

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

Using Webb’s near-infrared spectrograph, astronomers have captured new images of Neptune that finally reveal the planet’s mysterious auroral activity. Faint hints of Neptune’s auroras were first ...

The planet’s elusive aurorae are much colder than expected, which is how they evaded detection for so long.

Scientists observed and captured the first clear evidence of auroras on Neptune using the James Webb Space Telescope (JWST), ...

An SwRI-led study modeled the chemistry of TOI-270 d, a nearby exoplanet between Earth and Neptune in size, finding evidence ...

"It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me." ...

Neptune's unique blue light. The planet's auroras are captured vividly in great detail by NASA's Webb telescope ...

Since auroral activity is based where the magnetic fields converge into the planet's atmosphere, Neptune's auroras are far from its rotational poles. The groundbreaking detection of Neptune's ...
