Schroter’s Valley Rille in False Color

Schroter's Valley Rille in False Color
This color-composite focuses on a section of Schroter's Valley (rille) and employs ultraviolet- to visible-color-ratio information to accentuate differences that are potentially diagnostic of ilmenite- (i.e, titanium oxide) bearing materials as well as pyroclastic glasses. Bluer units in these images suggest enrichment in opaque phases in a relative sense. The magenta color indicates dark mantle material which scientists believe contains titanium-bearing pyroclastic material. The images were acquired Aug. 21, 2005. The processing was accomplished by the Hubble Space Telescope Lunar Exploration Team at NASA's Goddard Space Flight Center, Northwestern University, and the Space Telescope Science Institute. False-color images were constructed using the red channel as 502/250 nanometers; the green as 502 nanometers; and the blue as 250/658 nanometers. North is at the top in the image.

About the Object

  • Distance
    DistanceThe 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.
    The Moon is 238,857 miles (384,403 kilometers) from the Earth.
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    The Moon has a diameter of 2160 miles (3476 kilometers).
