Galaxy and Its Classification In Astrophysics Quiz Questions with Answers

The galaxy is a huge collection of billions of stars, as well as a vast amount of hydrogen and dust in an isolated place in the universe called a galaxy. There are many types of this, such as the black hole is a supernova explosion that scatters matter into envelopes in space. The heavy core continues to contract and becomes a neutron star. The fate of a neutron star again depends on its mass. It has been speculated that massive neutron stars may contract indefinitely. This implies that a large amount of matter in the neutron star will eventually be packed into a single point, such an infinitely dense object is called a black-hole, nothing will escape it, not even light. Black holes are therefore invisible. Pulsar, the variable star born as the remainder of the supernova is called a pulsar. Let's know more about Galaxy and Its Classification.
