Two Faces of Uranus (Hubble)

 Two Faces of Uranus (Hubble)

These Hubble Space Telescope images show the varied faces of Uranus. On the left, Uranus in 2005 displays its ring system. The planet — along with its rings and moons — is tipped on its side, rotating at roughly a 90-degree angle from the plane of its orbit. In the Hubble close-up taken just one year later, Uranus reveals its banded structure and a mysterious dark storm.

About The Data
Data Description The HST observations include those from program M. Showalter (SETI Institute) and J. Lissauer (NASA Ames Research Center) and L. Sromovsky (University of Wisconsin, Madison), H. Hammel (Space Science Institute), and K. Rages (SETI Institute).
Instrument ACS/WFC
Exposure Dates August 2005 and August 23, 2006
Filters Left: Clear, F330W, F475W, F606W, F814W Right: F550M, F658N, and F775W
About The Image
Color Info These images are a composite of separate exposures acquired by the ACS instrument 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: Left: Blue: F330W Green: F475W Orange: F606W Red: F814W Right: Blue: F550M Green: F658N Red: F775W
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.
