SN 1987A [See Link] was a supernova in the Tarantula Nebula in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 168,000 light years from Earth, close enough that it was visible to the naked eye. It was the closest observed supernova since SN 1604, which occurred in the Milky Way. The light from the supernova reached Earth on February 23, 1987. As the first supernova discovered in 1987, it was labeled "1987A".

Just to add to Cosmospups good answer for a bit of further interest.
SN1987A was a type 2a supernovae and should have resulted in a neutron star but continuous monitoring from the Hubble space telescope as failed to find the star. 3 possibilities for this could be 1) it is surrounded and hidden by dust, 2) further mass collapsed back on the star turning it into a black hole or 3) it became a quark star.

It is about 168,000 light years away from us in the Large Magellanic Cloud so it occurred about 168,000 years ago.

When was supernova 1987a discovered?
It was first observed on February 23, 1987.
How did supernova SN 1987A differ from most other observed supernovae?
It was visible with the naked eye.It did not originate within the Milky Way.
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.
What year was supernova seen?
Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.
What is the absolute magnitude of 1987A halo?
It had a peak magnitude of +2.9
Why did the supernova 1987A actually occur in 1977?
It didn't. It occurred approximately 168,000 years before 1987.
What was Ian Shelton famous for?
Discovering supernova 1987A!
When was supernova 1987a discovered?
It was first observed on February 23, 1987.
What was the significant on 14 January 1987?
The only date close to this that is Nova related was February 23rd when Supernova 1987A was observed.
How did supernova SN 1987A differ from most other observed supernovae?
It was visible with the naked eye.It did not originate within the Milky Way.
Why is supernova 1987A important to astronomers?
SN1987A was the the closest observed supernova since the invention of the telescope. The previous supernova, SN1604 was only observed with basic equipment and of course the naked eye.It also gave astronomers the ability to calculate it's distance at 168,000 light years.

When was the last super nova seen in the milkey way galaxy and who saw it?
SN 2006gy 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 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 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 eventsSN1987A was a supernova in the outskirts of the Tarantula Nebula.

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.
