Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away ...

PITTSBURGH (KDKA) -- We have another question to answer, and this one has to deal with some very interesting clouds. Ray C. took a picture just outside of Uniontown, Pennsylvania, where you can see ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

EVANSTON, Ill. (CBS) -- A Northwestern University astrophysicist is part of an international team of scientists creating a gravitational wave detector system that will eventually be launched into ...

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 ...

We have known for several decades that the universe is expanding. Scientists use multiple techniques to measure the present-day expansion rate of the universe, known as the Hubble constant. These ...

Solar eclipses don’t just look cool – they can send gravity waves rippling through Earth’s atmosphere like dropping a stone in a pond. An international team of students has measured these gravity ...

Gravity waves are caused by air being forced up and over terrain such as the Appalachians in stable atmospheric conditions.
