The Hubble Space Telescope captured these images of the mysterious ice giants Uranus, left, and Neptune, right. Shortly after launch in 2021, the James Webb Space Telescope will unlock secrets of the atmospheres of both planets.

| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3 and ACS instruments on the Hubble Space Telescope. Several filters were used to sample specific 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: Uranus: Blue: F330W Green: F475W Orange: F606W Red: F814W Neptune: Blue: F467M Green: F547M Yellow: F657N Orange: F763M Red: F845M |
| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
