Webb captured seven of Neptune’s 14 known moons: Galatea, Naiad, Thalassa, Despina, Proteus, Larissa, and Triton. Neptune’s large and unusual moon, Triton, dominates this Webb portrait of Neptune as a very bright point of light sporting diffraction spikes.

The new James Webb Space Telescope is being pointed all over the universe and into our own backyard. Astronomers took data on Neptune from the sun. The first pictures of this world were released by NASA.

Neptune is a bright blue planet due to the presence of methane. The "Near-Infrared Camera" photos show a white planet because the telescope observes light in the part of the spectrum that is not visible to the naked eye. There is methane in Neptune's atmosphere.

The exception to this is the planet's high altitude methane ice clouds, which reflect sunlight before it can be absorbed by the methane. NASA says these appear to be brilliant.

The new image shows Neptune's rings, which have not been seen in years. Neptune's brightness makes it hard to see the rings from afar. The rings were found by the telescope.

"It has been three decades since we last saw these faint, dusty rings, and this is the first time we've seen them in theIR," said the scientist.

There are 14 moons in the Neptune system. Above Neptune is the most prominent image in this one. The color is due to a sheet of nitrogen ice covering the area.

There is a problem with one of the observing modes of the instrument. The mechanism that supports the medium-resolution mode has encountered some problems. NASA is looking at the problem and trying to find a solution. Eric Smith, NASA's program scientist for the telescope, said Wednesday that he doesn't think the issue will prevent the instrument from being used.
