Neutron+Star

A neutron star is the remains of a supernova. It is made of particles from the previous star before the supernova. These materials would include elements like gold, silver & iron. Even though it is only 20 kilometers in diameter, it has three times the mass of the sun. A neutron star is the core of a star. When a supernova occurs, it is compressed & collapses into a neutron star. It has a high rotational speed which is about 1.4 ms to 30 seconds. Contributing to the high speed, it also has a very strong gravitational pull. Anything that comes near a neutron star is crunched & destroyed; even the matter of the object is destroyed. This is because of the immense gravity. Sometimes a neturon star can collapse, before turning into a black hole, but only if the mass of the object is high enough. A single teaspoon from a neutron star would weigh a billion tonnes!

 The neutron stars were discovered in 1932 and afterwards in 1934 a suggestion was made by Walter Baade and Fritz Zwicky that neutron stars were formed by a supernova. A neutron star has a mass of about 1.35-2.1 solar masses, with a solar mass being the equivalent of the mass of the sun. As the name suggests, a neutron star is full of neutrons. PSR J0108-1431 is the closest known neutron star to Earth. Its dispersion measure is 1.83 pc cm^-3. Another example that can be given is, located 980 light years away from sun. It was confirmed in 2007 that three extrasolar planets orbit it. 17000 light years away is located PSR B1509-58 in the Circinus constellation by the Chandra X-ray Observatory.

We will not be able to live sufficiently on any neutron star. The most basic reason is that the gravity is overwhelming on any neutron star. We would be simply be crushed due to the immense pressure on us. Furthermore, the basic reason for extraterrestrial investigations is because of the small space yet large population. A neutron star only has an average diameter of 20 km. Then why should we continue our search when we would need thousands of neutron stars just to make a second earth. The atmosphere would also be too harsh for any kind of human life.

Even if we wanted to live on any neutron star, then it would simply be too far away for reaching it. Of course, there is a solution like everything else in the world. If any neutron stars are coming at a rate, past us (not at us, or the it would crash into the earth), then we can identify it by seeing the colour of it, which would be blue. This is because of the light's spectrum.

It would take us thousands of years just to get to PSR B1509-58 at the fastest rocket's speed. Therefore it is necessary for further investigation about any other technology or just shiftings of these stars.
