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, and ...

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 ...

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 ...

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

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 ...

Neptune harbors cosmic secrets, in part because of its distance from Earth. But researchers have just unlocked one of the planet's mysteries by using the unique capabilities of the James Webb Space ...

Neptune lies in the frigid, dark, vast frontier of the outer edges of our solar system, about 3 billion miles away from the sun. For the first time, NASA's James Webb Space Telescope has captured ...
