Chandra X-ray Images of Tycho's Supernova Remnantt
By combining observations from over 15 years with the Chandra X-ray Observatory and 30 years with the Very Large Array, scientists have been able to learn new things about Tycho's supernova remnant and the explosion that created it. These still frames from the time-lapse movie show the expansion of the Tycho remnant, allowing a detailed study of how the debris field is expanding. In a series of five images from Chandra taken between 2000 and 2015, low-energy X-rays are red, the medium band of X-rays is green, and the highest-energy X-rays Chandra detected are blue.

Radio Images of Tycho's Supernova Remnant
With some 30 years of observations in radio waves with the VLA, astronomers have also produced a movie, using three different images. Astronomers have used the X-ray and radio data to learn new things about this supernova and its remnant.
