Latest Crab Nebula Stories
NASA's Space Shuttle Columbia carried the Chandra X-ray Observatory into space 15 years ago, deploying it on July 23, 1999.
WASHINGTON, July 22, 2014 /PRNewswire-USNewswire/ -- Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia.
University College of London researchers have explained for the first time the details of how the Sun’s coronal mass ejections behave when falling back onto the star’s surface.
A new model developed by researchers at the University of Southampton explains how the spin of a pulsar slows down as the star gets older.
In a galaxy not that far away, astronomically speaking at least, researchers using NASA's Chandra X-ray Observatory have detected the first x-rays emitted by the debris of a young supernova, SN 1957D.
Astrophysicists have detected pulsed gamma-ray emissions from the Crab pulsar with energies that exceed 100 billion electron-volts (GeV). These gamma-ray pulses surpass what current theoretical models of pulsars can explain.
Beginning Sunday, September 18, 2011 at NASA's launch facility in Fort Sumner, New Mexico, space scientists from the University of New Hampshire will attempt to send a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth.
"Zombie" stars that explode like bombs as they die, only to revive by sucking matter out of other stars.
WASHINGTON, May 11, 2011 /PRNewswire-USNewswire/ -- The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any flare previously seen from the object.
A gamma-ray burst released by the Crab Nebula on April 12 has shocked astronomers.
Pulsar -- A pulsar, which originally stood for pulsating radio source, is a rapidly rotating neutron star, whose electromagnetic radiation is observed in regularly spaced interval, or pulses. Pulsars are closely related to magnetars, the main difference being the strenght of the object's magnetic field. History Pulsars were discovered by Jocelyn Bell and Antony Hewish in 1967 while they were using a radio array to study the scintillation of quasars. They found a very regular...
Crab Nebula -- The Crab Nebula (Messier 1, NGC 1952) is the object the which started Charles Messier logging non-cometary objects on his Messier Catalog. It is the expanding cloud of gas thrown off in the explosion that gave rise to the 1054 supernova recorded by Chinese astronomers, now more than 6 light years across (the nebula is currently expanding at 1000 km/sec and the total mass of ejected material is about 0.1 solar masses). The supernova which produced it was bright enough to...
