Extended Groth Strip
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of many separate exposures made by the WFPC2 instrument on the Hubble Space Telescope using two different filters to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F606W (V) Green: F555W (V) + F814W (I) Red: F814W (I)

Compass and Scale
Compass and ScaleAn astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made.
