English: Tycho Supernova Remnant, SN 1572
Polski: Pozosta?o?? po supernowej Tychona, SN 1572
English: This composite image of the Tycho supernova remnant combines infrared and X-ray observations obtained with NASA's Spitzer and Chandra space observatories, respectively, and the Calar Alto observatory, Spain. It shows the scene more than four centuries after the brilliant star explosion witnessed by Tycho Brahe and other astronomers of that era. The explosion has left a blazing hot cloud of expanding debris (green and yellow). The location of the blast's outer shock wave can be seen as a blue sphere of ultra-energetic electrons. Newly synthesized dust in the ejected material and heated pre-existing dust from the area around the supernova radiate at infrared wavelengths of 24 microns (red). Foreground and background stars in the image are white.

Photo's description:
This image from NASA's Wide-field Infrared Survey Explorer (WISE) takes in several interesting objects in the constellation Cassiopeia, none of which are easily seen in visible light. The red circle visible in the upper left part of the image is SN 1572, often called “Tycho’s Supernova”. In the centre of the image is a star forming nebula of dust and gas, called S175 (in the Sharpless catalog of ionized nebula). This cloud of material is about 3,500 light years away and 35 light-years across. It is being heated by radiation from young hot stars within it, and the dust within the cloud radiates infrared light. On the left edge of the image, between the Tycho supernova remnant and the very bright star, is an open cluster of stars, King 1, first catalogued by Ivan King, an astronomer at UC Berkeley. This cluster is about 6,000 light-years away, 4 light-years across and is about 2 billion years old. Also of interest in the lower right of the image is a cluster of very red sources. Almost all of these sources have no counterparts in visible light images, and only some have been catalogued by previous infrared surveys.
