Latest SN Stories
New work on the Tycho supernova remnant has measured a reverse shock penetrating the remnant at more than 1,000 times the speed of sound in the gas.
A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope ample opportunity to gain some clues about the origins of cosmic rays.
A progenitor of a type 1a supernova may have been found, according to findings published in the journal Monthly Notices of the Royal Astronomical Society.
Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy.
NASA's Hubble Space Telescope has helped astronomers solve a 40-year mystery over what type of star, or so-called progenitor, caused a supernova in a nearby galaxy.
Scientists have discovered that a supernova that exploded in August was a "white dwarf" star, and its companion star could not have been a "red giant."
G299.2-2.9 is an intriguing supernova remnant found about 16,000 light years away in the Milky Way galaxy.
Tycho Brahe -- Tycho Brahe (December 14, 1546 - October 24, 1601) was a Danish astronomer. He had Uraniborg built; which become an early "research institute". For purposes of publication, Tycho owned a printing press and paper mill. His best known assistant was Kepler. Tycho realized that progress in the science of astronomy could be achieved, not by occasional haphazard observations, but only by systematic and rigorous observation, night after night, and by using instruments of the...
Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....
