Will two rare supernovas finally tell us how fast the universe is expanding? Perhaps, but we'll have to wait for it for them ...

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

The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...

JWST observations of galaxy cluster MACS J1149 show gravitational lensing used by CANUCS to study distant low-mass galaxies across a wide range of cosmic time.

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 ...

Cosmic Microwave Background (CMB) polarized light subjected to gravitational lensing effects, in addition to cosmic birefringence. On the far left, the white lines show the polarization pattern of the ...

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 vast majority of matter is dark – invisible until it is detected only through its gravitational effects. The newly discovered object could be a clump of dark matter, or it could also be a compact, ...

This Hubble Wide Field Camera 3 image demonstrates the immense effects of gravity; more specifically, it shows the effects of gravitational lensing caused by a galaxy cluster called SDSS J1152+3313.

Around 37,000 citizen scientists combed through 430,000 images to help an international team of researchers to discover 29 new gravitational lens candidates through Space Warps, an online ...

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 ...
