The Hunt for Life in Alpha Centauri

This oddball system of three stars might be our best chance at finding nearby life in the Universe.
This composite image contains X-ray data from Chandra (green and blue) that show heated material in the center of a shell generated by a supernova explosion. Optical data from Hubble show the glowing pink rim, which is ambient gas being shocked by the blast wave from the supernova, as well as the surrounding star field. The Type Ia supernova that resulted in the creation of this remnant would have been visible from Earth some 400 years ago.
