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 cooling suggests that the region of the atmosphere can change greatly despite the planet's distance from the Sun. Astronomers now hope to study Neptune over a full solar cycle, which 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 ...
