When did Supernova 1987A really go supernova?
1987A’s light reached Earth on February 23, 1987, and as the earliest supernova discovered that year, was labeled “1987A”….SN 1987A.

Why was Supernova 1987A so important?
Studying supernovae like SN 1987A is important because the exploding stars create elements, such as carbon and iron, that make up new stars, galaxies, and even humans. The iron in a person’s blood, for example, was manufactured in supernova explosions. SN 1987A ejected 20,000 Earth masses of radioactive iron.
Where did the supernova 1987A occur?
Supernova 1987A is located in a nearby galaxy called the Large Magellanic Cloud. This galaxy is about 160,000 light years from Earth, so when it was first observed by optical telescopes in 1987, the event had actually occurred about 158,013 B.C. We are seeing a delayed-action replay of the actual event.
Who played 1987 Super Bowl?
The Giants
The Giants defeated the Broncos, 39–20, for their first Super Bowl and first NFL title since 1956. The game was played on January 25, 1987, at the Rose Bowl in Pasadena, California.
Was Supernova 1987A visible to the naked eye?
It was so bright that it was visible to the naked eye from Earth’s surface, emitting the power of a 100 million Suns. On February 23, 1987, the brightest supernova in almost four centuries years was observed in the Large Magellanic Cloud, a small galaxy on the outskirts of the Milky Way.
What was the cost of a 30 second sport during the 1987 Super Bowl?
Super Bowl commercial price history
Year | Price of 30-second commercial |
---|---|
1986 | $550,000 |
1987 | $600,000 |
1988 | $645,500 |

Did the supernova really explode in the year 1987 when it was observed here on Earth in 1987?
The strikingly bright shock waves from a massive star explosion first observed in 1987 can still be seen today, three decades later. This brilliant star explosion, called Supernova 1987A, occurred only 160,000 light-years from Earth in a satellite galaxy of the Milky Way known as the Large Magellanic Cloud.
