Who discovered the first supernova?
The first recorded supernova was observed by Chinese astronomers in 185 AD, which is known as SN 185. However, the discovery of the first modern supernova, SN 1572, was made by the astronomer Tycho Brahe in 1572.
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.
How many gamma rays travel after a supernova?
Gamma rays from a supernova can travel vast distances, potentially out to light-years away from the source. They can be detected by astronomers on Earth using specialized instruments, giving us valuable insights into the explosion and its aftermath.
How many neutrinos from supernova SN 1987A were detected on Earth?
There are somewhere around 65 billion neutrinos per second passing through every square centimeter perpendicular to the Sun. By far the majority of those also come out the other side... baryonic matter is essentially transparent to neutrinos.
Why was the discovery of the Chinese observation of a supernova in Taurus important?
# Ancient records of SN 185 could be the earliest written description of a supernova. # It may have shown that the night sky was not a permanent fixture # It would certainly have "scared" a few people, not knowing what it was
What is the earliest cretinism can be detected?
When they ask their first question.
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.

Can you tell you are pregnant within 3 to 4 days?
No. 14 days after sex at the earliest pregnancy can be detected.

What is the Vela Supernova?
The Vela Supernova is the remnant of a supernova explosion that occurred in the Vela constellation about 11,000 to 12,300 years ago. It is located about 800 light-years away from Earth and is one of the closest known supernova remnants to us.
What is the adverb phrase of a black hole is the remains of a supermassive star after a supernova?
"after a supernova" is the adverb phrase in the sentence.
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.
What gives a star light?
