NASA’s twin Voyager spacecraft, Voyager 1 and Voyager 2, embarked on a historic journey to explore the outer planets of our solar system. Taking advantage of a rare planetary alignment, the probes ...

A new analysis of decades' worth of observations has revealed that Uranus does indeed emit more heat than it receives from the rays of the Sun.

Jupiter, Saturn, and Neptune each emit more energy than they receive from the Sun, meaning they have comparatively warm ...

Scientists looked at decades' worth of data, combining reports and readings from various spacecraft and new computer modeling ...

But scientists now say that Uranus is actually warmed from the inside, according to a study published in Geophysical Research ...

Researchers from the University of Houston, led by Dr. Xinyue Wang, launched a deep probe of Uranus’ data — and determined ...

The discovery challenges findings made by Voyager 2, which collected data suggesting Uranus, unlike other giant planets in ...

But the study also revealed another mystery, as the team measured the temperature of the top of Neptune’s atmosphere for the first time since Voyager 2’s flyby.

For decades, astronomers have caught fleeting glimpses of auroral activity on Neptune—most notably during NASA’s Voyager 2 flyby in 1989.

Hints of auroras were first faintly detected in ultraviolet light during a flyby of the Voyager 2 spacecraft in 1989. Webb captured Neptune's shimmering lights in infrared light, providing direct ...
