∙ 14y agoSN 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

Who recorded the first supernova?
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.
Why can a supernova be seen in outerspace but not heard?
Because empty space cannot propagate sound.
What is the largest supernova?
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.
Can the earth go supernova?
No. There are two ways of generating a supernova: a star at least 8 times the mass of the sun collapsing and exploding or a white dwarf interacting or colliding with a companion star. Our sun is not massive enough to explode when it dies and does not have a companion star.
What can the maximum brightness of a supernova be compared to what?
There aren't really any comparisons to be made to a supernova. Let's try one; a supernova is as much brighter than the Sun is as the Sun is to a flashlight. A supernova will release as much energy in an hour as a regular star does in its entire 10-billion year life.
When was kelpers supernova seen?
1604.
The light from the most recent supernova that was visible to the unaided eye arrived at Earth in what year?
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.
Has there been a recorded supernova in the Milky Way?
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.
What is a guest star was that seen exploding over China in the year 1054?
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.

Grab nebula was first seen on earth in 1054 how long did it take to get here?
Supernova(SN) 1054 Crab Supernova was first seen in 1054, it is estimated to be 6,500 light years away, so 6,500 years
Why is the Crab Nebula considered a supernova remnant?
Because it IS a supernova remnant. It's the visial remains of a star that expolded and was seen in 1054. Designated SN 1054.
Why can a supernova be seen in outerspace but not heard?
Because empty space cannot propagate sound.

What happens in a year to a supernova?
It's gamma rays will have traveled one light year.
What was the Crab Nebula caused by?
The Crab Nebula was formed when it's host star exploded as a supernova [See related question]
Is Antares a supernova yet?
It's highly unlikely. Antares is not likely to go supernova for at least a million years. However, because of it's distance from us - 600 light years, it may have already gone supernova and we just haven't seen it yet.
