Remember that Supernovas are great contributors to interstellar material that forms new stars. The star which explodes to supernova will leave either a pulsar or a black hole depending on its mass. Part of the supernova will scatter into space.
It is said that a hypernova can release around 100 times more energy than a supernova. Supernova's will reach temperatures of 100 billion degrees centigrade, and will release more energy in 15 seconds than our sun does in it's entire lifetime!
It is extremely rare for four tornadoes to occur simultaneously in the same area. Tornadoes typically form from separate thunderstorms and are usually isolated events. Multiple tornadoes can occur in quick succession or in the same general area, but having four at the same time is highly unlikely.
SN 2006gy was the brightest and largest supernova ever discovered, scientists announced. The star was in the NGC 1260 galaxy, in the same direction as the constellation Perseus and may be a type of supernova previously predicted by theory but not observed. The conclusion was reached after extended observations of the supernova by both optical telescopes and X-ray telescopy. Currently, there are two possible explanations for the supernova's brightness, but both require the star in question to have been at least a hundred times as massive as the sun. Although the supernova is brighter than SN 1987A, which was bright enough to be seen by the naked eye, SN 2006gy is too far away to be seen by the naked eye.
Compared to a supernova, a nuclear bomb would be like a puff of breath in a hurricane. Even a SMALL star is the equivalent of millions of hydrogen bombs PER SECOND, and a supernova is billions of times more powerful. However, a nuclear explosion IS like one grain of sand out of the center of a star; with a temperature of millions of degrees for a tiny fraction of a second.
Most stars are dimmer than our sun (intrinsic brightness), and thus we cannot see them. However, most of the stars that we can see are actually quite a bit brighter than our sun. Some of them are exceedingly bright.
"Supernovae" is a plural form of "supernova"
All it means that there were more than one observations which had the same value.
no
It's not the same as a supernova--the Crab Nebula is the visible remnant of a supernova event which occurred about 7,500 years ago. The light from the supernova explosion reached the earth and was observed by Chinese and Arab astronomers about 1,000 years ago. The Crab Nebula was the first object to be identified with a supernova which was actually observed during recorded history.
Yes. Debridement of pressure sores (decubitus ulcers) can occur many times, if need be.
An object further away will appear less bright than the same object closer to us. However, a supernova can emit the same brightness as our Sun does in it's whole lifetime, in a very short period of time - a nova on the other hand, at maximum brightness is only about 100,000 times that of the Sun.
Yes, multiple aneurysms can occur.
No there isn't. Microbursts are not all that uncommon, and they usually occur in the same season, increasing the liklihood they would occur near the same time of the year. And if the climate in one area permits microbursts, then it isn't surprising that they will occur more than once.
Lightning does occur in different places, but many more times then 2!
once more
The Pandora app can play a song more than once in the same day.
