Even at Neptune's incredible distance from the sun, astronomers have long suspected it has auroras, though they had never seen them until now. The James Webb Space Telescope, a collaboration of ...

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 a long time, it was unclear what auroral activity, if any, might be present on Uranus and Neptune, so far from the Sun: Uranus orbits at around 19 times the distance between the Sun and Earth ...

Being the furthest planet from Earth, we don't know much about Neptune, but recent observations have revealed something glowing in its sky.

However, at Neptune’s surface, the gravity is only about 1.1 times the gravity we experience on Earth. In other words, if something weighed 100 pounds on Earth, you would find it weighs 110 pounds on ...

This colder temperature suggests why Neptune's auroras have remained undetected for so long as it would result in much fainter auroras. This cooling suggests that the region of the atmosphere can ...

“And by golly, it was.” Astronomers have been searching for auroral activity on Neptune, the most distant planet from the sun, since NASA’s Voyager 2 spacecraft flew by it in 1989 and picked ...

Neptune harbors cosmic secrets, in part because of its distance from Earth ... It takes Neptune 165 years to complete one orbit around the sun •Neptune was discovered on Sept.
