How did supernova SN 1987A differ from most other observed supernovae?
It was visible with the naked eye.It did not originate within the Milky Way.
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".
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. It could be seen with the naked eye from the Southern Hemisphere.
Using the velocity of light devise a strategy for finding out when the supernova actually occurred relative to when the Chinese astronomers saw the explosion in 1054 Use the equation drt?
The distance to SN 1054 is about 6,300 light years. The date it was seen is 1054 x - y =z
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.
How many Sn atoms are there in a 86.0 gram sample of Sn?
86.0 grams Sn (1 mole Sn/118.7 grams)(6.022 X 1023/1 mole Sn)= 4.36 X 1023 atoms of tin=================
The worlds biggest supernova?
Sn 2006gy [See Link] was observed on May 7, 2007, by NASA and several other astronomers who described it as the "brightest stellar explosion ever recorded.The kinetic energy released by the explosion has been estimated at 1052 ergs (1045 J)
How do you look up a serial number?
Many manufacturer's have sn data on their website. Many books have been written about manufacturers that have sn data.
What year was supernova seen?
Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.Several supernovas have been observed, in different years.
What is the symbol of tin?
Sn=====
What does tin sn mean?
The "Sn" used for tin comes from its Latin name like many other elements. It is an abbreviation of the Latin name "Stannum."
How many atoms are in 2.09 moles of Sn?
2.09 moles Sn (6.022 X 10^23 atoms / 1 mole Sn) = 1.26 X 10^24 atoms of tin
