Merging black holes and neutron stars have unusual oval orbits prior to colliding and merging, which challenge the laws of ...

Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together but orbiting in an ...

A fleet of NASA space telescopes has traced a brief flash of gamma rays to a likely collision between two neutron stars, placing the violent event inside a tiny, gas-shrouded galaxy that had escaped ...

An international team of scientists, including Northwestern University astrophysicists, has detected 128 new ...

WASHINGTON, March 11 (Reuters) - A supernova - the explosion marking the end of a massive star's life - is one of the brightest cosmic events, usually about a billion times more luminous than the sun.

A cosmic mystery surrounding the universe's most dazzling explosions, superluminous supernovas, appears to have been solved by scientists studying a colossal stellar event a billion light-years from ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

(Santa Barbara, Calif.) — For decades, astronomers have used distant supernovae as cosmic lighthouses to test fundamental physics and to measure the universe. For Joseph Farah, a fifth-year graduate ...

The catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

Astronomers have for the first time seen the birth of a magnetar—a highly magnetized, spinning neutron star—and confirmed that it's the power source behind some of the brightest exploding stars in the ...

In December 2024, astronomers watched a star around 25 times the mass of our sun die in a blaze of glory. Located one billion light-years from Earth, SN 2024afav was a prime example of a superluminous ...
