Latest SN Stories
The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud.
Astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) have found that a supernova discovered last year was caused by two colliding white dwarf stars. The white dwarfs were siblings orbiting each other.
NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula â€” the shattered remains of a supernova that exploded thousands of years ago.
Scientists have created a stunning new image of one of the youngest supernova remnants in the galaxy. This new view of the debris of an exploded star helps astronomers solve a long-standing mystery.
In a feat resembling an intergalactic autopsy, astronomers have used the Gemini South telescope in Chile to obtain a detailed spectrum of an echo of light from an ancient supernova that enables them to identify the original starâ€™s cause of death.
Scientists using NASA's Chandra X-ray Observatory have witnessed a cosmic rite of passage, the transition from a supernova to a supernova remnant, a process that has never seen in much detail until now, leaving it poorly defined.
A distant supernova that exploded 41,000 years ago may have led to the extinction of the mammoth. This theory joins the list of possible culprits responsible for the demise of mammoths, which last roamed North America roughly 13,000 years ago. Scientists have long eyed climate change, disease, or intensive hunting by humans as likely suspects.
Astronomers have found compelling evidence that a supernova shock wave has produced a large amount of cosmic rays, particles of mysterious origin that constantly bombard the Earth. This discovery, made with NASA's Chandra X-ray Observatory, supports theoretical arguments that shock waves from stellar explosions may be a primary source of cosmic rays.
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time that associated dust has been detected.
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....
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
