Image titled "Neptune, NIRCam, Labeled." Image has a mostly dark background with one extremely bright point of light that dominates the upper left quadrant of the image and a glowing sphere towards the bottom middle of the image. The extremely bright point of light at the upper left of the image has 8 spikes pointing out from a center bright point like a compass. This is labeled Triton. The glowing sphere, is mostly white, almost neon, with a few extremely bright patches representing methane-ice clouds. The glowing sphere is accompanied by several narrow, faint rings and 6 tiny white dots, which are Neptune's moons. They are labeled as Galatea, Naiad, Thalassa, Despina, Proteus and Larissa. Splattered throughout the mostly black background are about 10 small, dim, blurry circles which represent distant galaxies.

About This Image
In this version of Webb’s Near-Infrared Camera (NIRCam) image of Neptune, the planet’s visible moons are labeled. Neptune has 14 known satellites, and seven of them are visible in this image.

Triton, the bright spot of light in the upper left of this image, far outshines Neptune because the planet’s atmosphere is darkened by methane absorption at wavelengths captured by Webb. Triton reflects an average of 70 percent of the sunlight that hits it. Triton, which orbits Neptune in a backward orbit, is suspected to have originally been a Kuiper belt object that was gravitationally captured by Neptune.

NIRCam was built by a team at the University of Arizona and Lockheed Martin’s Advanced Technology Center.

About The Object
Object Name   Neptune
Object Description   Gas giant
Distance   Neptune's average distance from Earth is 2.7 billion miles
About The Data
Data Description   This image was created from JWST data from proposal: 2739 (K. Pontoppidan). 
Instrument   NIRCam
Exposure Dates   12 July 2022
Filters   F140M, F210M, F300M, F460M
About The Image
Color Info   These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infraraed wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Red: F460M Orange: F300M Green: F210M Blue: F140M
