SN 2006gy [See Link] was an extremely energetic supernova that was discovered on September 18, 2006. Although about one hundred times as luminous as SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy was more than 1,400 times as far away as SN 1987A, and too far away to be seen without a telescope.
SN1987A [See Link]was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere.
It was the closest observed supernova since SN 1604 The light from the supernova reached Earth on February 23, 1987.
SN1604 [See Link] was seen on October 9th, 1604 generally a supernova occurs once every fifty years but the universe has been in a drought for these supernatural awesome events
The name is formed from SN (yes SuperNova), the year of discovery, then followed by a one or two letter designation. SN is optional.The first 26 of the year get designated with an upper case letter from A to Z. then, pairs of lowercase letters are used, starting with aa, ab.... etcetera Historical supernovae were known simply by the year they occurred: SN185, SN1572 SN1604. Since 1885, the letter notation was used.
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.
Because empty space cannot propagate sound.
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.
SN 2006gy was the brightest and largest supernova ever discovered, scientists announced. The star was in the NGC 1260 galaxy, in the same direction as the constellation Perseus and may be a type of supernova previously predicted by theory but not observed. The conclusion was reached after extended observations of the supernova by both optical telescopes and X-ray telescopy. Currently, there are two possible explanations for the supernova's brightness, but both require the star in question to have been at least a hundred times as massive as the sun. Although the supernova is brighter than SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy is too far away to be seen by the naked eye.

SN1987A was a supernova in the outskirts of the Tarantula Nebula. It could be seen with the naked eye from the Southern Hemisphere in 1987.
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.
A "guest" star is the name for the original star, before it exploded as a Supernova. Because the Supernova is the explosion and has no real physical relation to the Star, it is termed "guest" star.

Because it IS a supernova remnant. It's the visial remains of a star that expolded and was seen in 1054. Designated SN 1054.

The Crab Nebula is about 6,500 light-years away from Earth. Since one light-year is the distance light travels in one year, it took 6,500 years for the light from the Crab Nebula's explosion in 1054 to reach Earth.
It's gamma rays will have traveled one light year.
