Latest Supernova remnants Stories
Once a star, the Veil Nebula is now a twisted mass of shockwaves that appears to be six-times the size of our moon, but it sure is nice to look at – as demonstrated by a high-resolution image captured by the Hubble Space Telescope and released by the ESA on Monday.
A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of high-energy particles.
In 1987 astronomers witnessed the violent death of a giant star in the form of a supernova, and now researchers have published results of their extensive ‘autopsy’ which yielded surprising results.
Less than two months after it first began repeatedly scanning the sky, the ESA’s Gaia space observatory has discovered its first supernova – a powerful stellar explosion that had occurred in a distant galaxy located some 500 million light-years from Earth.
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.
Based on observations taken from the Spitzer Space Telescope, NASA scientists have uncovered evidence of a rare Type Ia supernova scenario – when a white dwarf feeds off an aging giant, to the point of explosion.
For the first time, astronomers have peered into the heart of an exploding star during the final minutes of its life.
NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles.
Tycho Brahe -- Tycho Brahe (December 14, 1546 - October 24, 1601) was a Danish astronomer. He had Uraniborg built; which become an early "research institute". For purposes of publication, Tycho owned a printing press and paper mill. His best known assistant was Kepler. Tycho realized that progress in the science of astronomy could be achieved, not by occasional haphazard observations, but only by systematic and rigorous observation, night after night, and by using instruments of the...
Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...
Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....
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...
