Scientists discover the ‘most massive neutron star ever detected’

Astronomers have discovered the “most massive neutron star ever measured,” amassing to more than two times the mass of our sun, that they dub “almost too massive to exist,” according to a statement from researchers at the Green Bank Observatory.

“A neutron star is what remains when a very massive star goes supernova and dies, it is an extremely dense dead stellar core,” Thankful Cromartie, 27, a graduate student at the University of Virginia and Grote Reber pre-doctoral fellow at the National Radio Astronomy Observatory, as well as lead author on the study published Monday in Nature Astronomy, explained to ABC News.

“These city-sized objects are essentially ginormous atomic nuclei. They are so massive that their interiors take on weird properties. Finding the maximum mass that physics and nature will allow can teach us a great deal about this otherwise inaccessible realm in astrophysics,” Cromartie said in a statement announcing their findings.

Just a sugar-cube sized piece of this neutron star would weigh 100 million tons on Earth, scientists said.

Cromartie added to ABC News that the discovery of the mass of this star is a big leap forward in understanding these mysterious objects.

“The main reason finding the most massive neutron star ever discovered is significant is because it helps us understand the physics deep inside their interiors,” Cromartie told ABC News. “Neutron stars are the second most massive things in the universe after black holes.”

“I think the discovery is very compelling because it shows that we can use astrophysical observations as kind of a laboratory in space to do physics that we can’t do on earth,” she said of the research. “We can’t exactly make neutron stars here on earth so the only way we have access to this astrophysics is by observing these neutron stars.”

“I think it’s a pretty darn cool tool to have access to,” she added.
