Located approximately 4,600 light-years away and 330,000 times larger than Earth, the neutron star was formed from the remains of a supernova when a giant star collapses

Typically, neutron stars are the same size as a city,
and are made "so tightly packed," according to NASA, that a sugar-cube-size material weighs more than [a billion] tons.

Using the Green Bank Telescope located in West Virginia
the team of researchers observed both a white dwarf star and a neutron star
By measuring the white dwarf -
a dead star's low-density corpse - and the neutron star
interacting with each other, the team can measure the size of the neutron star.

According to Albert Einstein's general relativity theory
the gravity around the dwarf star is slightly distorted as these masses orbit each other

The discovery of the largest neutron star known to mankind is no small feat
Dense masses such as J0740 + 6620
can help scientists understand
how massive neutron stars can be before gravity moves forward and becomes a black hole.

"Neutron stars have this tipping point,
where their internal densities become so extreme
that the force of gravity stops the neutron's ability to collapse further
