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.
When did supernova 1987A occurred?
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".
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.
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 do measurements of neutrinos from the sun pose a problem for modern astronomy?
At present, no problems. 15 years ago, scientists had no explanation for the small number of solar neutrinos detected at our Earth. Either we didn't understand neutrino formation in our Sun, our detectors were wrong, or neutrinos had the capacity to decay. The latter seemed to be the least likely possibility, so scientists argued for many years which of the first two was correct. In 1998 it was discovered that neutrinos do, indeed, decay into other neutrinos. The reason we weren't seeing as many neutrinos as we expected was because the ones we were expecting to see had decayed into other types. So the solar neutrino problem is no longer a problem.

Can neutrinos change into other types of neutrinos?
Yes; the scienific terminology for this phenomenon is "neutrino oscillation". Neutrinos exist in three different flavours - electron, muon and tao neutrinos, listed in order of increasing mass (each also has an antiparticle). Although it is not know why this is the case, it was originally discovered that neutrinos oscillate when examining the neutrinos emitted by the sun; although primarily electron neutrinos are emitted as a result of the fusion process within the sun, the quantities of the different flavours of neutrinos detected on Earth from the sun are in roughly equal proportions.

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.

Are neutrinos dangerous to the earth?
Neutrinos are not harmful to Earth or its inhabitants. They interact extremely weakly with matter and pass through our planet as well as us without causing any harm. Millions of neutrinos pass through us every second without us even noticing.
What Are Particles That Enter Earth's Atmosphere Called?
THIS IS NOT SPELLED WRONG Neutrinos.
Can neutrinoes pass through all matirials in the Earth?
Neutrinos can pass through most materials in the Earth, including rock and metal, with almost no interactions due to their extremely weak interaction with matter. However, some materials, like lead or water, may absorb or scatter neutrinos to a small extent. Overall, neutrinos are able to travel through vast amounts of matter without being significantly absorbed or deflected.
