The best place to observe the stars is among them, which is why Hubble and the James Webb Space Telescope have been deployed outside Earth's murky atmosphere. At least, that's the case when you're ...

“LIGO has taken great strides, and are moving towards open data and reproducible science,” he says. “But I don’t think they’re quite there yet.” The Danish group’s independent checks, published in ...

This artwork imagines the ultimate front-row seat for GW250114, a powerful collision between two black holes observed in gravitational waves by the US National Science Foundation LIGO. It depicts the ...

A distant object that could be smallest known black hole, or the largest known neutron star, has been spotted by the LIGO–Virgo gravitational-wave detectors. The 2.6 solar-mass object appears to have ...

The LIGO-Virgo-KAGRA Collaboration unveiled several studies that shed important new light on the nature of gravitational waves—ripples in time and space produced by merging black holes and/or neutron ...

It has been three years since the Laser Interferometer Gravitational-Wave Observatory (LIGO) shut down, starting a long hiatus from searching the universe for gravitational waves. Now, though, the ...

It was the cosmic equivalent of a high-speed collision between a Ford-F550 and a Harley Sportster. Last year, on August 14, a black hole 23 times more massive than our sun smashed into a smaller ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. On August 17, 2017, an event occurred that forever changed how we ...
