Well, it may not always be possible to do this in every case, but there are certain things to look for.
Often a supernova will leave some relic behind, such as a pulsar or black hole, so you can look and see if there is one of these phenomena present.
Also (as in the case of the Crab Nebula) we know that there was a supernova some time in the past and we can see the result with our eyes. In this case we have a pulsar at the centre as well!
After a long time, if there are any gases present from the explosion, these may dissipate owing to the object's galactic motion or gravitational effects from passing stars (really the same thing!) so the Crab Nebula may not look quite so crablike in a few million years' time.

What is the magnitude of Cassiopeia A?
Cassiopeia A is a supernova remnant in the constellation Cassiopeia.It has no single point of luminosity, so no definitive magnitude can be attributed to it.
Make a sentence for astronomy?
An asteroid is a bunch of rocks moving through out solar system
How far is the closest star to earth?
The closest supernova, or more correctly supernova remnant, is the Vela supernova remnant [See Link] in the constellation Vela. The "guest" star exploded about 11 - 12,000 years ago and is located around 800 light years from Earth.
When did The Last Remnant happen?
The Last Remnant happened in 2008.
What neutron star is smaller than white dwarfs are thought to be remnants of .?
A neutron star is the remnant of a star, which - at the end of its life, and AFTER possibly losing a lot of mass (for instance, in a supernova explosion) has a remaining mass that is greater than the so-called Chandrasekhar limit.
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.
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.
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.
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?
supernova remnant
What determines what stage comes after a supernova?
The amount of mass in the remnant. If the mass of the remnant exceeds 3 solar masses then it will become a black hole.
What remnant does a supernova leave?
Depending on the mass of the original star, it is either a black hole or a neutron star.
Is a black hole a supernova remnant?
yes, it sure is. (if the core is massive enough.) if not, it becomes a Neutron Star.
What is a Stella nebula?
It does not exist.There are:Solar NebulaPlanetary NebulaH NebulaSupernova Nebula (Supernova Remnant)Or just plain nebula.
What are the 5 kinds of nebulea?
The 5 types of cosmic nebulae are: Reflection Emissive Dark Planetary Supernova remnant
