Berkeley, CA — Weak gravitational lensing is a uniquely promising way to learn how much dark matter there is in the Universe and how its distribution has evolved since the distant past. New work by a ...

In an extraordinary testament to the predictive power of Einstein’s theory of general relativity, a star system has been discovered that demonstrates extreme gravitational lensing. This observation ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it. Yet its gravity helps shape galaxies, and that makes ...

Maunakea, Hawai’i – Astronomers have captured a bizarre image of a supernova, the powerful explosion of a star, whose light was so warped by the gravity of a galaxy that it appears as multiple images ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S ...

Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that ...

The ring of light surrounding the centre of the galaxy NGC 6505, captured by ESA’s Euclid telescope, is a stunning example of an Einstein ring. NGC 6505 is acting as a gravitational lens, bending ...

NSF–DOE Vera C. Rubin Observatory, funded by the US National Science Foundation and US Department of Energy's Office of Science, will add an unprecedented amount of cosmological data to the study of ...

Dark matter is one of the most important and most mysterious questions in modern astronomy. Although dark matter cannot be seen or touched, it profoundly influences the formation and evolution of ...

(Nanowerk News) In a rare and extraordinary discovery, researchers have identified a unique configuration of galaxies that form the most exquisitely aligned gravitational lens found to date. The ...
