In the universe, there are many oddities, and chief of these is the neutron star. In essence, a neutron star is a massive atomic nucleus [or the centralized portion of the atom], where a teaspoon of such material [in theory] can have the weight of a mountain.

Research has been ongoing to determine just how large [or small] such an object really is. Through the use of satellites we may yet be able to measure the size of one, and learn what exists within as well.

This is due to research observing curious patterns of x-rays being emitted from various neutron stars. These x-ray emissions appear to involve material being sucked onto the neutron star from an orbiting companion.

As the material is drawn into the orbit of the neutron star, some of this material collides with the surface, radiating x-rays at the point of impact. The Hubbell was used to observe a lone neutron star a mere fourteen kilometers in radius, far below the maximum of 2.2 solar masses.

And for the first time, we now possess accurate limitations on radius and mass, as well as a working theorem as to what constitutes a neutron star. The composition of a neutron star is the Holy Grail in determining that fine line between neutron star…and black hole; we may soon truly know the difference.
