Chandra captures expanding debris from Tycho’s supernova remnant

Astronomers have observed the debris field from the supernova of 1572, now known as Tycho’s supernova remnant, with NASA’s Chandra X-ray Observatory and the NSF’s Karl G. Jansky Very Large Array (VLA). By combining the X-ray data with some 30 years of observations in radio waves, astronomers have also produced a movie showing the expansion from the explosion is still continuing 444 years later.
