Two black holes spiraled into each other in a spectacular collision 1.3 billion years ago. The black holes in a galaxy far, ...

In 2015, a piece of equipment at an observatory in the US moved one quintillionth (10-18) of a meter. This tiny movement was the first recorded event of gravitational waves. And it helped confirm ...

Gravity wave clouds form in wave-like patterns in sky, oftentimes resembling ripples in a body of water from a rock being thrown. These types of clouds are created from air in the atmosphere coming ...

As Hurricane Helene slammed into Florida on September 26 as a Category 4 hurricane, it brought destruction and death across the U.S. Southeast. The storm claimed over 230 lives, making it the ...

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

The Earth’s atmosphere is host to a diverse spectrum of wave phenomena, among which acoustic-gravity waves occupy a pivotal role. These waves arise from the interplay between compressional (acoustic) ...

In about 11 years, one of humankind’s most ambitious missions is set to launch into space. Decades in the making, the Laser Interferometer Space Antenna, or LISA, could revolutionize our understanding ...

After detection, there's a small window of time within which follow-up, light-based astronomy observations can be made. When you purchase through links on our site, we may earn an affiliate commission ...
