Munich, September 26 : Using a web of telescopes, astronomers have identified one of the nearest supernovae in the last 25 years, a decade after it exploded.
This result was made possible by combining data from the vast online archives from many of the world’s premier telescopes.
The supernova, called SN 1996cr, was first singled out in 2001 by Franz Bauer.
Bauer noticed a bright, variable source in the Circinus spiral galaxy, using NASA’s Chandra X-ray Observatory. Although the source displayed some exceptional properties Bauer and his Penn State colleagues could not identify its nature confidently at the time.
It was not until years later that Bauer and his team were able to confirm that this object was a supernova.
