Our Cosmic Connections Activity - Image Descriptions

The name and type of object and/or artist illustration for each of the images is listed below. The stage of stellar evolution is indicated by the bold type. The URL for each of the deep sky objects is listed. For more specific information concerning the sequencing or selection of the images please refer to the Teacher Guide and Answer Key.

  1. Planet Earth

  2. Sirius B (bright object in foreground) is a white dwarf in a binary system with Sirius A (dim object in the background) - a 2 solar mass main sequence star.

  3. DEM L71 is a Type Ia supernova remnant in the Large Magellanic cloud. It is the remains of a supernova explosion that destroyed a white dwarf star.
