Supernova 1987A is the bright light source at the centre of the image, near the Tarantula Nebula. SN 1987A was a type II supernova in the Large Magellanic Cloud, a dwarf satellite galaxy of the Milky Way. It occurred approximately 51.4 kiloparsecs (168,000 light-years) [a] from Earth and was the closest observed supernova since Kepler's ...
Texas Supernova Search (TSS) is one of many ongoing projects to identify and record supernova events. The project is led by Robert Quimby and to date has found 35 supernovae, 29 of which they were the first to report on. In addition they have discovered twelve (extragalactic) novae (in M31 and M33, including a probable LBV) and six dwarf novae.
This is a list of supernova candidates, or stars that are believed to soon become supernovae. Type II supernova progenitors include stars with at least 8~10 solar masses that are in the final stages of their evolution.
Astronomers have taken the first close-up image of a star beyond our galaxy, and it’s a “monster star” surrounded by a cocoon as it slowly dies.
The rate of supernova discovery steadily increased throughout the twentieth century. [51] In the 1990s, several automated supernova search programs were initiated. The Leuschner Observatory Supernova Search program was begun in 1992 at Leuschner Observatory. It was joined the same year by the Berkeley Automated Imaging Telescope program.
An asteroid nearly the size of a football field now has roughly a 0.28% chance of hitting Earth in about eight years, NASA says — though at one point earlier its estimate reached as high as 3.1% ...
SN 2006jc was a type Ibn supernova that was detected on October 9, 2006 in the galaxy UGC 4904, which is about 77 million light-years away in the constellation Lynx. [1] [2] It was first seen by Japanese amateur astronomer KÅichi Itagaki, American amateur Tim Puckett, and Italian amateur Roberto Gorelli. [2]
The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in the Milky Way, our home galaxy, or in a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. As of March 2021, [1] SNEWS has
