On January 14, 2025, a gravitational wave dubbed GW250114 reached Earth. Like its predecessor, GW150914, it came from a pair ...

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence. In those systems, the dense remnant can ...

Gravitational-wave astronomy has exploded since 2015, capturing hundreds of black hole and neutron star collisions. With ever ...

Researchers have spent 10 years improving the massive detectors they use to catch shockwaves from colliding black holes, and ...

Archaeologists uncover 59 sealed mummy coffins at Saqqara, Egypt, many believed to hold the remains of ancient priests. This ...

Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...

Science advances through data that don't fit our current understanding. At least that was Thomas Kuhn's theory in his famous ...

A decade ago, the universe whispered, and humanity, for the first time, had the tools to listen. On September 14, 2015, the ...

In a significant breakthrough, astronomers have recently discovered a “ghost star” nestled within the remnants of a supernova ...

Researchers have spent ten years improving the massive detectors they use to catch shockwaves from colliding black holes, and ...

In the Universe, thermonuclear fusion is a common reaction: it is the source of energy for stars. On Earth producing energy ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...
