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 […]

Discovery Alert: ‘Baby’ Planet Photographed in a Ring around a Star for the First Time!
Discovery Alert: ‘Baby’ Planet Photographed in a Ring around a Star for the First Time! Researchers have discovered a young protoplanet called WISPIT 2b embedded in a ring-shaped gap in a disk encircling a young star, marking the first time a planet has been directly observed in one of these gaps. The protoplanet WISPIT 2b […]

There’s less water on distant planets than previously thought
There’s less water on distant planets than previously thought Researchers at ETH Zurich have found that distant planets outside our solar system have much less water on their surfaces than previously thought. The study, which used computer simulations to model planetary evolution, shows that sub-Neptunes like K2-18b are unlikely to be “Hycean worlds” with large […]

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 […]

NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion
NASA’s Chandra Reveals Star’s Inner Conflict Before Explosion NASA’s Chandra X-ray Observatory has revealed that a star called Cassiopeia A (Cas A) underwent a violent rearrangement of its interior just hours before it exploded as a supernova. The study found that part of an inner layer rich in silicon traveled outwards and broke into a […]
