gravitational-waves

Gravitational wave astronomy has seen plenty of improvements since the original signal was captured in 2015 . Despite that, it remains an engineering challenge to actually create the detectors needed for the precise measurements required to spot gravitational waves. A new NASA Innovative Advanced Concepts (NIAC) grant is funding a concept from a team led by Paul Stankus at Brookhaven National Lab…

A mysterious hum of gravitational waves that fills the cosmos may be the echo of long-dead "dark stars" that served as the seeds of the first supermassive black holes.

A faint gravitational-wave signal spreading across the universe may contain clues about mysterious stars that existed more than 13 billion years ago, according to new research. Scientists from Colgate University have investigated whether some of the earliest supermassive black holes could be responsible for much of the extremely low-frequency gravitational-wave background detected today. Their fi…

Here’s a LIGO insider’s description of how he got the news of a phenomenon that had first been theorized 100 years ago.

Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
