When a gravitational lens magnifies a background galaxy, why don't we see the object doing the lensing, as we would if ...

A new citizen science project invites the public to scan never-before-seen images from the Euclid Space Telescope in search ...

A spectacular cosmic event nicknamed “SN Winny” could help solve one of astronomy’s biggest mysteries: how fast the universe is expanding. This rare superluminous supernova, located 10 billion ...

Citizen science project uses Euclid telescope data to find gravitational lenses. Public helps identify light-bending galaxies ...

A recently released image taken by the Hubble Space Telescope shows a distant galaxy that has been warped and distorted by a phenomenon called gravitational lensing. This phenomenon allows scientists ...

The Bullet Cluster, originally detected using weak lensing NASA/CXC/CfA/M.Markevitch et al.; Optical: NASA/STScI; Magellan/U.Arizona/D.Clowe et al.; Lensing Map: NASA ...

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 ...

The Hubble Space Telescope is a constant source of beautiful pictures of the wonders of space, and this week’s Hubble image shows a wonderful example of a phenomenon called gravitational lensing, ...

Astronomers using NASA’s Hubble Space Telescope have unexpectedly discovered the most distant galaxy that acts as a cosmic magnifying glass. This monster elliptical galaxy appears in the Hubble images ...

Bending of light by dark matter is a vital observational tool in cosmology. So if you are going to use cosmology to accuse financial institutions of a "blind faith in maths", you might at least google ...

White dwarfs are the remnants of stars like the Sun. They also provide some of the best means to measure large distances in the Universe if they explode as “type Ia” supernovae. All of those ...
