SN 185 [See Link] was a supernova which appeared in the year 185, near the direction of Alpha Centauri. This "guest star" was observed by Chinese astronomers in the Book of Later Han, and may have been recorded in Roman literature.
This is believed to have been the first supernova recorded by humankind.
The word supernova was first used by Fritz Zwicky, a Swiss astrophysicist and astronomer, and was first seen in print in 1926. The word was from the original German, Haupt Nova.This comes from Nova (plural novae) which means "new" in Latin.
The earliest supernova that has ever been recorded happened in 185 AD. Some Chinese astronomers first saw it.
The discovery of the crab nebula, a supernova remnant, seems to correspond to a bright supernova recorded by Chinese astronomers in 1054. The nebula was later described by John Bevis in 1731.
There have been several recorded supernovae in the Milky Way. The earliest recorded Milky Way supernova was SN 185 (seen, as the name implies, in 185 C.E.), and the most recent supernova recorded was SN 1604 (seen in 1604 C.E.), or Kepler's Supernova.
It's not the same as a supernova--the Crab Nebula is the visible remnant of a supernova event which occurred about 7,500 years ago. The light from the supernova explosion reached the earth and was observed by Chinese and Arab astronomers about 1,000 years ago. The Crab Nebula was the first object to be identified with a supernova which was actually observed during recorded history.
The supernova explosion that created the nebula was seen in 1054 AD by probably everyone, but was recorded by Chinese and Arab astronomers. The first recorded siting of the nebula was in 1731 by John Bevis.
SN 185 was a supernova first seen in the year 185, near the direction of Alpha Centauri, between the constellations Circinus and Centaurus. This "guest star" was observed by Chinese astronomers and may have been recorded inRoman literature. It remained visible in the night sky for eight months. It is believed to have been the first supernova recorded by humankind. The gaseous shell RCW 86 is suspected as being the supernova remnant of this event. The distance to this object is estimated to 1 kpc. Recent X-ray studies show a good match for the expected age
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
Nobody can tell when the FIRST Supernova occurred, but the first recorded Supernova was in 185SN 185 was a supernova which appeared in the year 185, near the direction of Alpha Centauri This "guest star" was observed by Chinese astronomers and possibly been recorded in Roman literature. It remained visible in the night sky for eight months. This is believed to have been the first supernova recorded by humankind.However the first stars formed around 400 million years after the big bang. These were supermassive stars - called population III stars - they were much larger than stars today, so their life times would have been a few million years. They would have exploded as supernova and ended as black holes. These black holes could have been the starting blocks for the galaxies.
In the Milky Way, a supernova occurs about once every 50 years.
Probably the Vela supernova in the southern constellation Vela. Its source supernova exploded approximately 11,000-12,300 years ago (and was about 800 light years away).
