One of two things happens when neutron stars collide: they merge together to form a new, larger neutron star, or they collapse into a black hole. But which happens when? That leads to another, trickier question: How big can a neutron star get?
An exotic type of 'hybrid' star has been discovered nearly 40 years since it was first theorized, but until now has been curiously difficult to find.
NASA Goddard has created an impressive supercomputer simulation of one of the most violent events in the Universe: A battle to the death between two neutron stars, ripping each other apart and colliding until they form a black hole. Even if it's just a simulation, looking at the scale and forces involved blows my…
See that purple stream at the bottom right? It's the helical jet from a runaway pulsar that's streaking across the Milky Way at speeds reaching five million mph. But more extraordinary than that is how freakishly long this thing is.
Previously, astronomers had been under the impression that the heavy elements—gold, platinum, lead, uranium, etc.—came from supernova explosions. But now, scientists have announced a new theory for these highly valuable elements, this one involving two ultra-dense neutron stars and one spectacularly violent, grossly…
Late last week we told you about those unexplained — but extremely powerful — radio bursts that originated from another galaxy. A number of theories have been proposed to account for the phenomenon, but there’s one in particular that caught our attention: Blitzars — the final stage of a supramassive neutron star.
Astronomers studying an absolutely enormous neutron star and its white dwarf companion have shown that Einstein’s calculations still work even under the most extreme gravitational conditions.
In this week's "Ask a Physicist" we're going to consider an incredibly ill-conceived mission: a trip to a neutron star to extract the gooey neutrons inside. What happens next? You die. We'll find out how.
A teaspoon of this stuff would weigh 100 million tons, and the only thing more dense is a black hole. Space is weird.
