What is the name for a supernova cloud?
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
A what is produced when the outer core of a star explodes after the core collapses?
The process of the stellar explosion is called a "nova", or if powerful enough, a "supernova". The outer layers of gas are blown away into space, and this shell of fleeing gas is sometimes called a "supernova remnant", or more generally, a "nebula". For example, the Crab Nebula is the gas cloud left over after a supernova explosion which was brilliantly visible here on Earth in the year 1054.
Does a supernova implode or explode to form a black hole?
It depends on the mass of the star. When massive stars die the result is usually an enormous explosion called a supernova, but the core will collapse to form a dense remnant. If the remnant is less than 3 times the mass of the sun then it will form a neutron star. If it is greater than 3 times the mass of the sun it will form a black hole. Extremely massive stars may collapse directly into a black hole with no supernova.
The Crab Nebula is a supernova remnant In which constellation is it located?
In the constellation of Taurus
A spinning neutron star has been observed at the center of a?

Can a pulsar change into a supernova?
No. A pulsar is a remnant left behind by a supernova.
What Remnant can stretch over a distance of several light-years?
A supernova remnant.
Is crab nebula same as supernova?
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.
Why is the Crab Nebula considered a supernova remnant?
Because it IS a supernova remnant. It's the visial remains of a star that expolded and was seen in 1054. Designated SN 1054.
What is a neatron star?
Let me presume that the questioner means "neutron star". When a massive star dies in a supernova explosion, one possible outcome is that the remnant left behind is a neutron star. It's called that because it is essentially completely composed of neutrons; in effect, it is an atomic nucleus several kilometers in diameter. It gets that way because it is so massive (greater than 1.4 times the mass of the Sun) that gravity crushes the protons and electrons together to make neutrons. Packing all of these neutrons together with the already-existing neutrons gives rise to a quantum-mechanical pressure that prevents the star from collapsing any further. So the remnant becomes a giant ball of neutrons. If the remnant is more massive than about 3 times the mass of the Sun, gravity will overcome even the resisting pressure of the neutrons, and will crush the remnant to form a black hole. No known mechanism can resist this high gravitational force, and the equations of general relativity tell us that the remnant will be crushed to a mathematical point. (Additional quantum-mechanical effects will doubtless kick in before that happens, but as we do not yet have a full theory of quantum gravity, we don't really know the true outcome.)
How big is supernova cassiopeia?
Currently the expanding cloud from the supernova remnant is about 10 light years across.
What might happened to a star after it explodes as a supernova?
The supernova remnant will either be a neutron star or a black hole.
