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.
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.
The Crab Nebula is a pulsar wind nebula associated with the 1054 supernova.It is located about 6,500 light-years from the Earth. [1]A near-Earth supernova is an explosion resulting from the death of a star that occurs close enough to the Earth (less than roughly 10 to 300 parsecs [33 to 978 light-years] away [2]) to have noticeable effects on Earth's biosphere.
The yellow dots show the position uncertainty of asteroid 2024 YR4 when it encounters Earth in 2032, based on observations up to January 31, 2025.
As of 7 a.m CT on Sunday morning, the storm — which has reportedly caused at least 11 deaths — was 220 miles southeast of Corpus Christi, Texas, and had maximum sustained winds around 60 mph ...
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.
The National Hurricane Center is tracking three systems that could develop over the next week, Thursday, Sept. 19, 2024.
