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.
Supernova type codes, as summarised in the table above, are taxonomic: the type number is based on the light observed from the supernova, not necessarily its cause. For example, type Ia supernovae are produced by runaway fusion ignited on degenerate white dwarf progenitors, while the spectrally similar type Ib/c are produced from massive ...
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.
The last week of February holds a special celestial treat in store for astronomers and amateur stargazers. Mercury will become the seventh planet to line up in a current “planetary parade ...
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
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.
The National Hurricane Center is tracking three systems that could develop over the next week, Thursday, Sept. 19, 2024.
