Scientists have finally ‘heard’ the chorus of gravitational waves that ripple through the universe
This undated photo provided by researchers in June 2023 shows the Arecibo Telescope in Puerto Rico. This and several other telescopes around the world were used to observe the slow…
Europe’s space telescope launches to target universe’s dark mysteries
The Euclid spacecraft, pictured before being sent to Florida, will blast off on a mission to find out more about the ‘dark universe’ Europe’s Euclid space telescope blasted off Saturday…
Possible ‘Fingerprints’ of Gravitational Waves Found
Astronomers using data collected by CSIRO’s Parkes radio telescope, Murriyang, have found their strongest evidence yet for low-frequency gravitational waves. CSIRO’s Parkes Radio Telescope, Murriyang, on Wiradjuri Country. Image credit:…
NASA Goddard acoustics chamber and US marine band turn up the volume

Link Between Dark Matter and ‘Clumpiness’ of Universe
Researchers at the University of Toronto have revealed a theoretical breakthrough that may explain the nature of invisible dark matter and the universe’s large-scale structure known as the cosmic web.…
Double Quasar in Early Universe
Scientists have discovered a pair of gravitationally bound quasars inside two merging galaxies that existed when the universe was just 3 billion years old. An international group of researchers, including…

Cosmological models are built on a simple, century-old idea, but new observations demand a radical rethink
by David Wiltshire, Eoin O Colgain, Jenny Wagner and Shahin Sheikh-Jabbari, The Conversation Our ideas about the universe are based on a century-old simplification known as the cosmological principle. It…
Evidence for Slow-Rolling Sea of Gravitational Waves Found
Scientists are reporting the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves. The waves oscillate very slowly…
