It’s an open secret in astronomy that, practically wherever the James Webb Space Telescope (JWST) looks in the sky, a vast, ...

An international collaboration of scientists from Durham University in the UK, NASA’s Jet Propulsion Laboratory, and École ...

By studying how light from eight distant quasars is gravitationally lensed as it propagates towards Earth, astronomers have calculated a new value for the Hubble constant – a parameter that describes ...

Published in Nature Astronomy, the new map uses fresh observations by the James Webb Space Telescope, aimed at a well-studied ...

Imagine looking through space and seeing a super-bright supernova that you weren’t expecting to see. Then, after taking measurements, you come to the conclusion that the supernova is way brighter than ...

Why should it be that galaxies stand still where the greatest part of the universe can be overlooked? The latest reconstruction of the dark matter by the James Webb Space Telescope turns that question ...

Scientists utilize a technique called gravitational lensing to study galaxies and other celestial bodies that are too far away to observe directly. Gravitational lensing occurs when the light produced ...

A group of astronomers have made history by capturing an image of a record number of stars from a time when the universe was half its age. The astronomers detected 44 stars in the "Dragon Arc" galaxy, ...

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 ...

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 ...

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, ...
