Three NASA space telescopes teamed up to eye the supernova remnant SNR 0519.
suggest that the material in the blast wave likely slowed down after crashing into dense clouds of surrounding gas. If that's the case, the initial explosion would have occurred more recently than 670 years ago. Further observations from Hubble will help pinpoint exactly when the star exploded, according to the statement.
Using the data from the three telescopes, astronomers were able to create a composite image of SNR 0519, which NASA released on Sept. 12. The Chandra data captures X-rays from SNR 0519 with low, medium and high energies shown in green, blue, and purple, respectively. Optical data from Hubble shows the perimeter of the remnant in red, along with surrounding stars in white. The brightest regions in the X-ray data represent the slowest-moving material, whereas areas with no X-ray emissions are associated with faster-moving material, according to the statement.
