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.
It occurred approximately 51.4 kiloparsecs (168,000 light-years) [a] from Earth and was the closest observed supernova since Kepler's Supernova in 1604. Light and neutrinos from the explosion reached Earth on February 23, 1987, and it was designated "SN 1987A" as the first supernova discovered that year.
Map showing various supernova candidates, most of which are within one kiloparsec from the Solar System. [1] 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
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.
Those who want to see this event should start looking for the alignment as soon as the sun sets. Some places might have a better view of the alignment on different days. For example, in New York ...
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% ...
The pixel resolution in the cameras is 7.8 arc seconds, so follow-up observations on other telescopes are usually required to get a more accurate location. [2] The main goal of the project is to look for bright supernovae, and its discoveries have included the most powerful supernova event ever discovered, ASASSN-15lh.
