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".
What else can I help you with?
What made supernova 1987A so useful?
Supernova 1987A was useful because it was the first opportunity for scientists to study a nearby supernova in great detail. It provided valuable insights into the late stages of stellar evolution and the physics of supernova explosions. The data collected from Supernova 1987A has been instrumental in advancing our understanding of the life cycle of massive stars and the formation of elements in the universe.
When was supernova 1987a discovered?
It was first observed on February 23, 1987.
How did supernova SN 1987A differ from most other observed supernovae?
Supernova SN 1987A was the closest observed supernova to Earth in almost 400 years, allowing for detailed observations. It was also the first naked-eye supernova since the invention of the telescope. Additionally, SN 1987A marked the first time neutrinos were detected coming from a supernova, which provided valuable insights into the explosion process.
What is the absolute magnitude of 1987A halo?
The absolute magnitude of the 1987A supernova shock halo is estimated to range between -9 to -10 magnitudes in the visible light spectrum. This value indicates the intrinsic brightness of the halo if it were observed from a standard distance of 10 parsecs (32.6 light-years).
How did supernova 1987 get its name?
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.
Why did the supernova 1987A actually occur in 1977?
It didn't. It occurred approximately 168,000 years before 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.
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.

Where is the exploding star in the solar system?
There are no exploding stars (supernovae) in our solar system. Supernovae occur in distant parts of the galaxy, outside our solar system. The nearest known supernova to Earth was Supernova 1987A, which was located in the Large Magellanic Cloud, a satellite galaxy to our Milky Way.
