When was supernova 1987a discovered?
It was first observed on February 23, 1987.
What year was supernova seen?

How is it the super novas after the big bang didn't form black holes but rather elements?
There are two explanations. First, when a massive star forms a black hole, usually only a small portion of the star's mass actually goes into the black hole. Most of the rest is blasted away in a supernova, enriching the surrounding space with heavier elements. Second, there are also pair-instability supernovae. Such supernovae occur in extremely massive stars with a very low content of heavier elements, which likely existed in the early universe. Pair-instability supernovae will blow away the entire star, leaving behind no black hole or neutron star remnant.
Who discovered the supernova?
Since supernovas can be observed from earth with the naked eye they have been observed in prehistory (some archeaologists believe that ancient wall paintings depict supernovae) However the first person to ever record one was in 185BC by Chinese and Islamic observers.
Where do supernovas explode?
Anywhere there are massive stars. They are relatively rare events but many have been observed since records began. The first observed Supernova was in 185 in Centaurus and was almost as bright as the moon. Our closest candidate is IK Pegasi located at a distance of only 150 light years.
Is crab nebula same as 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.
When was supernova 1987a discovered?
It was first observed on February 23, 1987.
Where was the first supernova located?
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
Who first recorded this event the crab nebula?
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.
What was the first recorded supernova?
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.

Neutron capture produces what kind of elements in a star?
In a supernova explosion, neutron capture reactions take place, leading to the formation of heavy elements. There are two processes of neutron capture called rapid process (r-process) and the slow process (s-process) so these reactions lead to formation of different elements like: silicon, sulfur, chlorine, argon, sodium, potassium, calcium, scandium, titanium and iron peak elements (around mass number A=60): vanadium, chromium, manganese, iron, cobalt and nickel; gold, platinum, lead, hydrogen, oxygen are also formed. Radioactive titanium-44 in supernova remnant 1987A have been detected for the first time.
Who discovered the new star in Cassiopeia?
Although not noted as a supernova, the nebula "Cassiopeia A" was first observed by John Flamsteed on August 16, 1680. It is likely that intervening dust clouds obscured the brightness of the supernova, which might otherwise have been observed in 1667.Current estimates place the distance from Earth as around 11,000 light years. If that is correct, then the supernova explosion actually took place around 9,000 BCE. (see related link)
When was the Crab Nebula first observed?
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.

What is Tycho's star?
Tycho's Star is a supernova that was "discovered" by Danish astronomer Tycho Brahe in November of 1572 in the constellation of Cassiopeia. It was visible to the naked eye for 18 months, at its peak brilliance was brighter than the planet Venus and thus visible to the naked eye in broad daylight. This was the first "new star" noticed in the West in modern times. It confirmed Tycho in his suspicion that the heavens were not fixed and eternally unchanging. There seems to be some confusion as to whether the remnant of this supernova explosion -- visible today in a powerful telescope as a sphere of gas glowing at 50 million degrees Fahrenheit -- is indeed identical with Cassopeia A, the most powerful radio object in the sky after objects in our own solar system. Some sources on the net say Cassiopeia A is indeed the remnant of Tycho's Star, others that Cassiopeia A is the remnant of a supernova that exploded in or a little before 1680 and was briefly observed by Astronomer Royal John Flamsteed as a 6th magnitude star which he did not recognize as a "new star." I wish someone would clear up this discrepancy.
