One of the most stubborn issues in cosmology today concerns the universe's rate of expansion. Scientists know it's expanding, ...

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 ...

New satellite data has shed light on how mysterious gravitational forces may have shaped the universe. The first survey data from the European Space Agency’s pioneering Euclid satellite was made ...

A newly discovered cluster-scale strong gravitational lens, with a rare alignment of seven background lensed galaxies, provides a unique opportunity to study cosmology. In a rare and extraordinary ...

One hypothesis for the nature of dark matter is that some of it could be self-interacting, meaning the individual particles interact slightly with one another. When you purchase through links on our ...

The massive galaxy cluster can be found in the Ursa Major constellation within the northern hemisphere. As noted above, many of the galaxies around it look like streaks of light in Hubble's latest ...

With its Legacy Survey of Space and Time, the new observatory is expected to build the most precise map of the universe — ever. When you purchase through links on our site, we may earn an affiliate ...

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 ...
