When a planet's orbit brings it between Earth and a distant star, it's more than just a cosmic game of hide and seek. It's an ...

Diamond rain on Uranus and Neptune: Recent research suggests that extreme pressures and temperatures deep within Uranus and Neptune create conditions where carbon atoms crystallize into diamonds ...

NASA/ESA Hubble Space Telescope, Gemini North telescope and NASA Infrared Telescope Facility observations of Neptune and Uranus may have revealed why they differ in color. Credit: Directed by: Bethany ...

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 ...

However, imaging and confirming the auroras on Neptune has long evaded astronomers despite successful detections on Jupiter, Saturn, and Uranus. Neptune was the missing piece of the puzzle when it ...

Yet, unlike its neighboring giants, Jupiter, Saturn, and Uranus, Neptune’s auroras remained elusive. Despite previous attempts, capturing and confirming these celestial displays proved challengi ...

"It was so stunning to not just see the auroras, but the detail and clarity of the signature really shocked me." For the first time, astronomers have captured direct images of Neptune's elusive ...

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

Uranus seemed like a fairly calm, blue-green planet. But new findings from Hubble paint a different picture of Uranus.

While scientists have previously observed auroras on Mars, Jupiter, Saturn and Uranus, NASA’s James Webb Space Telescope (JWST) has finally spotted them on Neptune for the first time.

In 2023, researchers used the instrument to detect infrared auroras on Uranus. This time, it found them on Neptune as well. The images also allowed Hammel and her team to begin constructing a map ...
