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 ...

For the first time, the James Webb Space Telescope (JSWT) has revealed bright auroral activity on the planet Neptune. Capturing the auroral activity on the ice giant has been long in coming ...

K2-18b is a little over 120 light-years from Earth — on a galactic scale, this world is practically in our backyard.

"Neptune was the missing piece of the puzzle when it came to detecting auroras on the giant planets," said the European Space Agency.

Imagine a Slushee composed of ammonia and water encased in a hard shell of water ice. Now picture these ice-encrusted ...

But Webb's observations didn't just provide new pretty pictures of the ice giant planet's greenish-blue splotches. It revealed how odd Neptune's auroras are compared to other planets', glowing ...

The morning of April 24 will give rise to a striking mini-planetary parade, as Mercury, Venus, Saturn, Neptune, and Earth's ...

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 ...

For the first time, the James Webb Space Telescope (JSWT) has revealed bright auroral activity on the planet Neptune. Capturing the auroral activity on the ice giant has been long in coming, even ...

The detection of Neptune's auroras will help astronomers better understand how particles from the sun interact with its atmosphere, providing a new area of study about ice giant planets.
