October’s Night Sky Notes: Let’s Go, LIGO!
October’s Night Sky Notes: Let’s Go, LIGO! September 2025 marks the 10th anniversary of the first direct detection of gravitational waves by LIGO, a milestone that confirms Albert Einstein’s 1916 theory of General Relativity. Gravitational waves are ripples in space-time created by massive objects accelerating in space, such as black holes merging or stars going […]

The discovery of a gravitational wave 10 years ago shook astrophysics – these ripples in spacetime continue to reveal dark objects in the cosmos
The discovery of a gravitational wave 10 years ago shook astrophysics – these ripples in spacetime continue to reveal dark objects in the cosmos Gravitational waves were first detected in 2015 from the merger of two black holes, marking a major breakthrough in astrophysics and confirming one of Einstein’s predictions. The detection of gravitational waves […]

Meet ‘lite intermediate black holes,’ the supermassive black hole’s smaller, much more mysterious cousin
Meet ‘lite intermediate black holes,’ the supermassive black hole’s smaller, much more mysterious cousin Scientists have been searching for “lite intermediate black holes” (IMBHs), which are black holes with masses between stellar and supermassive black holes, as they can provide insights into how the universe grows and evolves. The detection of IMBHs is challenging due […]
