Where did the 1987 supernova occur?
Where did the 1987 supernova occur?
Supernova 1987A, first supernova observed in 1987 (hence its designation) and the nearest to Earth in more than three centuries. It occurred in the Large Magellanic Cloud, a satellite galaxy of the Milky Way Galaxy that lies about 160,000 light-years distant.
When did the supernova in 1987 actually occur?
February 23-24, 1987
The explosion occurred 160,000 years ago, on the outskirts of the Tarantula Nebula in the Large Magellanic Cloud – a nearby dwarf galaxy. The light of the explosion – traveling at 186,000 miles per second (300 million meters per second) – finally reached Earth on February 23-24, 1987.
What year will a supernova happen?
2037
Now, looking far beyond the solar system, astronomers have added a solid prediction of an event happening deep in intergalactic space: an image of an exploding star, dubbed Supernova Requiem, which will appear around the year 2037.
When was the last galactic supernova?
1604
The most recent supernova to be seen in the Milky Way galaxy was SN 1604, which was observed on October 9, 1604.
Who Discovered 1987 supernova?
Ian Shelton
SN 1987A was discovered independently by Ian Shelton and Oscar Duhalde at the Las Campanas Observatory in Chile on February 24, 1987, and within the same 24 hours by Albert Jones in New Zealand. Later investigations found photographs showing the supernova brightening rapidly early on February 23.
How big was sk69202?
Sk-69202, Progenitor of SN 1987A It presumed to have a mass of about 20 solar masses. Blue supergiant stars are typically characterized by an O-Type spectrum.
How was the supernova SN 1987A unusual?
How was the supernova SN 1987A unusual? it originated with a blue supergiant, neutrinos from the explosion were observed on Earth, and it is the only supernova for which the precursor star is known.
Is there going to be a supernova in 2022?
This is exciting space news and worth sharing with more sky watch enthusiasts. In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades.
Can a supernova destroy a galaxy?
Supernovas are created during the last moments of a star’s life. These gigantic explosions can wipe out galaxies and the planets inside them. These powerful eruptions are called supernovae. They can emit the same energy in a single instant that our sun will generate in over 1 million years.
How many times brighter did sanduleak 202 appear on the sky after it exploded?
The progenitor star (inset), a blue supergi ant called Sanduleak -690 202, was about 80,000 times bright er than the sun; at its brightest (in May, 1987), the supernova reached 200 million solar luminosities.
Why is Supernova 1987A so important?
Why is Supernova 1987a so important? Named SN 1987A, it was the first supernova since 1604 to be visible to the naked eye. Astronomers credit Hubble’s sharp vision with yielding important clues about the massive star’s demise. This caused its heating and the generation of x-rays-the x-ray flux from the ring increased by a factor of three
Which object was a supernova observed in 1987?
In 1987, there was a supernova explosion in the Large Magellanic Cloud, a companion galaxy to the Milky Way. Supernova 1987A, which is shown at the top of the page, is close enough to continuously observe as it changes over time, thus greatly expanding astronomers’ understanding of this fascinating phenomenon.
What causes a supernova to explode?
Supernovae are caused by the explosion of a massive star, and the explosions have been thought to arise through one of two mechanisms. In the first type, called Type Ia , massive stars can explode like a stick of dynamite, leaving no collapsed remnant.
What is the closest supernova to Earth?
The closest star to Earth is the red dwarf Proxima Centauri just over four light years away, but there is no chance of it going supernova. Theoretically, though, if a star were to go supernova one light year away from Earth it would rip our planet and the entire solar system to shreds.
