A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.

The two ends of the nebula are marked by FLIERs, lobes of fast moving gas often tinted red in false-color pictures. [5] NGC 3242 can easily be observed with amateur telescopes and appears bluish-green to most observers. Larger telescopes can distinguish the outer halo as well. [6] At the center of NGC 3242 is an O-type star with a spectral type ...
Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
But officials also released a series of 10 stunning false-color images of the Chinese countryside. False colors cause water to show as blue, dirt in gray and plants in red -- the images have a sci ...
This view, taken with infrared light, is a false-color image of a quasar-starburst tandem with the most luminous starburst ever seen in such a combination. Quasars show evidence of elements heavier than helium , indicating that galaxies underwent a massive phase of star formation , creating population III stars between the time of the Big Bang ...

The images are either visible spectrum photographs, images taken at non-visible wavelengths and displayed in false color, video footage, animations, artist's conceptions, or micrographs that relate to space or cosmology. Past images are stored in the APOD Archive, with the first image appearing on June 16, 1995. [3]
By combining the images from different filters they may also be used to produce false color images. Common filters are often used with the Hubble Space Telescope , forming the so-called HST-palette, with colors assigned as such: Red = S-II; Green = H-alpha; Blue = O-III.
