The star cluster NGC 2074 and peripheral nebulas in the Large Magellanic Cloud, a satellite of our Milky Way galaxy. The region lies about 170,000 light-years away in the constellation Dorado or the Sword-fish, and is invisible from Japan. This snapshot was made by the Hubble Space Telescope on 10 August 2008, one day before the Telescope completed 100,000 orbits since first being sent into space at 7:42 AM, August 11, 2008 U.S. Eastern time (8:42 PM Japan time).

This is an elliptical galaxy located in the center of the Perseus cluster of galaxies. The long thread-like filaments of light that stretch out into the surrounding galaxy cluster are given off by gas trapped in the strong magnetic field created from the supermassive black hole hosted by NGC 1275. This galaxy also gives off strong electric waves.

It is a very thin section of a remnant of the supernova SN1006, which first appeared in the constellation Lupus in 1006 A.D. Seen from the earth now, the remnant looks round and of the same diameter as the full moon, but in actuality it has a diameter of nearly 60 light-years.

Contemporary astronomers, through observations of the glight echoh of Cas A, have concluded that the initial supernova explosion occurred in the late 17th century. From analysis of the "light echo" shown here astronomers now surmise that the progenitor of Cas A was a red super giant that experienced an explosive outburst of Type IIb.
