Neutron stars are covered with “mountains” only fractions of a millimeter tall, new research shows, meaning these bumps are hundreds of times smaller than previous estimates had suggested. Neutron stars are compact stellar objects, similar in size to a large city with a diameter of...

Studying the violent collisions of black holes and neutron stars may soon provide a new measurement of the Universe’s expansion rate, helping to resolve a long-standing dispute, suggests a new simulation study led by researchers at UCL (University College London). Our two current best ways...

Astronomers are on the hunt for the remnants of the neutron-star collision that gave Earth its precious metals. When neutron stars merge, they spew a wealth of short-lived elements into their surroundings, and these materials become part of later-forming solar systems. Now scientists are trying...

Scientists may have caught the blinding flash of two dense neutron stars colliding to form a strange magnetic star. The first sign of the massive event was a gamma-ray beacon that appeared in telescope data on May 22, prompting astronomers to assemble their best instruments....

Astronomers are still focused on the collision of the two collapsed star cores that took place about 138 million light-years away and sent gravitational waves rippling through the universe. The afterglow of the neutron star has steadily brightened in recent months, and for now researchers...

Astronomers analyzing the first data from the Neutron star Interior Composition Explorer (NICER) mission have discovered two stars that revolve around each other every 38 minutes. One of the stars in the system, called IGR J17062–6143 (J17062 for short), is a rapidly spinning, super dense...

An unusual infrared light emission from a nearby neutron star detected by NASA’s Hubble Space Telescope could indicate new features never before seen. Could an unusual infrared light emission from a nearby neutron star RX J0806.4-4123 be a dusty disk or perhaps an energetic wind...
