One way to investigate dark matter is by using gravitational lensing. This animation shows light passing through a galaxy cluster, with its path bent by the gravity of the cluster. The amount of ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Gravitational lensing occurs when things with mass create ripples ...

Periodically, the European Space Agency (ESA) releases images that provide breathtaking views of the cosmos, courtesy of its premier missions. This includes a relative newcomer to party with the ...

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 ...

Peering into deep space, NASA's James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself ...

Combining the way that massive galaxies and galaxy clusters bend space and magnify our view of the distant universe with powerful new instruments sensitive to gravitational waves and electromagnetic ...

Pictures of gravitational lenses from the AGEL survey. The pictures are centred on the foreground galaxy and include the object name. Each panel includes the confirmed distance to the foreground ...

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 ...

Scientists have managed to weigh -- more precisely than any other technique -- a galaxy hosting a quasar, thanks to the fact that it acts as a gravitational lens. Detection of strong gravitational ...

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into ...

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 ...
