In 1989, the Voyager 2 spacecraft took the first pics of Neptune’s rings. Now, NASA’s James Webb Space Telescope is providing a more detailed look.

This composite shows thermal images of Neptune taken between 2006 and 2020. The first three images (2006, 2009, 2018) were taken with the VISIR instrument on ESO’s Very Large Telescope while the ...

Uranus and Neptune, on the other hand, are incredibly similar. Uranus is home to 13 known rings and 27 moons. Neptune has just five rings and 14 moons, the most famous of which is Triton.

Neptune is so far away that it's difficult to fathom: It sits roughly 30 times farther from the sun than Earth does. To put that into context, Jupiter is only five times farther from the sun than ...

Neptune, captured by the Voyager 2 spacecraft. A new study finds a link between the planet's cloud coverage and solar activity. NASA / JPL As the outermost planet in the solar system, Neptune is ...

In 1989, a dark spot was first discovered on Neptune by NASA’s Voyager 2 before the spots disappeared just a few years later.

Neptune has long been depicted as a deeper, darker blue than its fellow ice giant Uranus, but a new study shows that both are a similar shade of light greenish blue.

Neptune and Uranus are both ice planets in our solar system, but they possess different shades of blue. While Uranus has a pale cyan color, Neptune is a more vibrant blue.

Neptune has 14 known moons, and seven of them are visible in this labeled version of the recent JWST image. Triton, at top left, reflects an average of 70 percent of the sunlight that strikes it.

The last time scientists caught such a clear glimpse of Neptune's rings was when Voyager 2 flew past the distant planet in 1989. Now the James Webb Space Telescope has delivered a crisp new image.

In terms of mass, if you add up all the satellites of Neptune, Triton composes 99.5% of the mass of everything orbiting Neptune: moons, moonlets, and rings all included.

Neptune will then disappear at around 4:41 a.m. EDT (0841 GMT) when it drops below 21 degrees over the horizon to the southwest. The planet will set at around 6:41 a.m. EDT (1041 GMT).
