Crab nebula --a cloud-like nebula observed in the Crab constellation, the remnant of a supernova explosion observed in China in 1054. It contains a very rapidly rotating (and hence, young) pulsar, which is probably the remnant of the supernova.
Crab Nebula (M1)
(a) A supernova remnant in the constellation Taurus. The star that produced it exploded in A.D. 1054.
Crab Nebula
The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus .
CRAB NEBULA
The Crab Nebula (M1) is a cloud of intergalactic gas and dust. It is the remnant of a that was seen on Earth in 1054. The Crab Nebula can be found in the Taurus.
The Crab Nebula is one of the most fascinating "and instructive"cosmic objects anywhere.
The Crab Nebula, the remains of a star which went supernova in AD 1054. A powerful radio pulsar lies near the centre of the nebula.
The Crab Nebula, M1, was the first nebulous object observed by Charles Messier. It is a cloud of expanding gas left over from a supernova explosion. In the center of this nebula is a 16th magnitude star that is the collapsed core of the supernova.
The Crab nebula is one of the most famous Supernova Remnants.

Taurus contains the Crab Nebula (NGC 1952), the first Messier object ever to be listed. It is a pulsar wind nebula, which means that it is powered by the wind of a pulsar, found inside the shell of a supernova remnant.

Until 1987, only three had been positively identified in recorded history, the best known of which is the one that occurred in ad 1054 and is now known as the Crab nebula. Supernovas, like novas, are more often seen in other galaxies.
Today we look at this same part of the sky and see not only the Crab Nebula (which was discovered long ago) but also a pulsar right in the middle of the mess. The pulsar at the center is a pretty fast spinner, rotating at a rate of 30 times/second.
Why was the discovery of a pulsar in the Crab Nebula important?
Why aren't there any hydrogen lines seen in a type I supernova?
Why can nova recur, but never a supernova?

Then I'll show you where you can find a pulsar and remnants of a supernova - the Crab Nebula. (You need a telescope to see it but it's worth knowing where it hides.)

" I picked "Deep Sky, Named Objects, Crab Nebula" and the computer correctly responded that that nebula was below the horizon. So I picked the Helix Nebula from the scrolled list and pressed the GOTO button.
A famous supernova remnant is the Crab Nebula above. Chinese astronomers recorded the explosion on July 4, 1054 and the Anasazi Indians painted at least one picture of it.
The Crab Nebula, a steady source of so called TeV gamma-rays was first detected in 1989 by the Whipple Observatory (Az, USA). Modern Cherenkov telescope experiments like H.E.S.S.
The Crab Pulsar appears in optical photographs as a moderately bright (magnitude 16) star in the centre of the Crab Nebula.
Most of the star's substance is blown off, leaving behind, at least in some cases, an extremely dense core which (as in the Crab Nebula) may be a neutron star.
Supernova remnants like the Crab Nebula and HII regions like the Orion Nebula are also considered a part of the ISM, and make up most of the more spectacular visible examples of it.
"A few dozen pulsar wind nebulae are known, including the spectacular Crab Nebula, but none have the Mouse's combination of relatively young age and incredibly rapid motion through interstellar space, ...
The Crab Nebula, M1, was found by Hubble and others to match the location of a bright daytime star recorded by Chinese astronomers in 1054 AD and is now known to be a supernova remnant.
One of the most famous diffuse nebulae can be found in this constellation: the Crab Nebula, M1. In 1054 A.D. chinese observers recorded the appearance of a "new" star. M1 is the supernova remnant of the star which exploded then.
The remnant of that supernova, which contains the material ejected from the exploded star, becomes the Crab Nebula, or M1. M1 is visible through a small telescope.
This is the Crab Nebula, the leftover ejecta from a supernova explosion that took place in 1054 and was recorded in the records of Chinese astronomers. The remnant is kept glowing by energy from the rotating neutron star ("pulsar") at its center.

More objects were added later, bringing the total to 110. In it, M1 is the Crab Nebula, M2 is a globular cluster in Aquarius, M3 is a globular cluster in Canes Venatici, etc. For a list of the Messier objects, click here.
For three weeks it was so bright it could be seen in daylight. The only reason we know of it today is because Arab, Chinese, Japanese and Native American astronomers noted it. That supernova created what we now call the Crab Nebula.
The most famous supernova remnant is the Crab Nebula in Taurus, the remains of the great supernova of 1054, which was well observed by Chinese astronomers.
More information was added in the 20 next years such that its listings reached close to 15,000 objects. Astronomers refer to galaxies and nebulae by their NGC numbers. For example, the Crab Nebula is called NGC1952.
