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.
Texas City is an unincorporated community in Rector Township, Saline County, Illinois, United States. Texas City is located at the junction of U.S. Route 45 and County Highway 6 5 miles (8.0 km) north-northeast of Eldorado .
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.
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% ...
Many homes had roof and/or siding damage by this strong high-end EF2 tornado. Two mobile home parks were hit with several mobile homes being destroyed. Businesses and apartments were damaged and a large section of the roof of a FedEx warehouse collapsed as well. Twelve people were injured. [106] EF1 SSW of Union City: Branch: MI
The supernova exploded when the universe was 3.5 billion years old, rather than at today's date of 13.8 billion years old. The supernova progenitor was a white dwarf star, the progenitor of all Type Ia supernovae. The gravitational lens is galaxy cluster PLCK G165.7+67.0 (at a redshift of z=0.35), which lensed the supernova and its host galaxy ...
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.
