Cool image time! The Chandra science team has released a beautiful X-ray image of the remnant from the 1572 supernova first discovered by astronomer Tycho Brahe.
As with many supernova remnants, the Tycho supernova remnant, as it’s known today (or “Tycho,” for short), glows brightly in X-ray light because shock waves — similar to sonic booms from supersonic aircraft — generated by the stellar explosion heat the stellar debris up to millions of degrees. In its two decades of operation, NASA’s Chandra X-ray Observatory has captured unparalleled X-ray images of many supernova remnants.
Chandra reveals an intriguing pattern of bright clumps and fainter areas in Tycho. What caused this thicket of knots in the aftermath of this explosion? Did the explosion itself cause this clumpiness?
The image to the right, reduced to post here, is a composite of both X-ray (the remnant) and optical light (the background stars).
