Scientists are using data from Hubble data of the famous Cygnus Loop supernova remnant to study how these remnants change over time.
Some of the most dramatic events in the universe are the deaths of massive stars. When stars far larger than our sun run out of fuel and explode in huge supernovas, these events not only let out huge blasts of energy but also change the environment around them. As the shockwave from the explosion travels outward millions of miles into space and slams into clouds dust and gas, it can create elaborate and beautiful structures called supernova remnants.
“Hubble is the only way that we can actually watch what’s happening at the edge of the bubble with such clarity,” said Ravi Sankrit of the Space Telescope Science Institute, lead author of the new research, in a statement. “The Hubble images are spectacular when you look at them in detail. They’re telling us about the density differences encountered by the supernova shocks as they propagate through space, and the turbulence in the regions behind these shocks.
