The images also show a thin, bright line circling the planet’s equator. It could be a sign of Neptune’s atmosphere circulating, powering its winds and storms, according to a statement from NASA .

The images of Uranus, the seventh planet from the sun, and Neptune, the eighth planet, were collected in 1986 and 1989, respectively, as NASA's Voyager 2 spacecraft headed out of the solar system.

New images from the space-based observatory offer a novel view of the planet in infrared. By Jonathan O’Callaghan No spacecraft has visited Neptune since 1989, when the NASA probe Voyager 2 flew ...

For the first time in history, we now have real, high-resolution images of Neptune that go beyond artist impressions and telescope visuals. Captured by advanced space telescopes and spacecraft ...

Astronomers have used telescope data to color-correct Voyager 2 images of Neptune and Uranus, revealing that the planets have a similar greenish blue hue. CNN values your feedback 1.

Neptune isn't as blue as people think, ... He says the images captured by this spacecraft were taken with different color filters. PATRICK IRWIN: It's got a green filter.

Since then, Neptune has remained the only planet not to have direct evidence of its auroras. With Webb’s latest images, scientists finally have the full picture of auroral activity throughout ...

S cientists observed and captured the first clear evidence of auroras on Neptune using the James Webb Space Telescope (JWST), marking a milestone in the study of the outer reaches of the solar system.

Because Neptune is about 30 times farther from the sun than Earth is, it gets only a faction of a percent of Earth's sunlight, meaning Voyager 2 had to take long-exposure images.
