An image of a gravitationally lensed galaxy was recently captured ... that takes place when huge celestial bodies, like a galaxy cluster, causes the light passing though it to bend.

This phenomenon occurs when the gravity of a massive object, such as a galaxy or galaxy cluster, bends and amplifies the light ... By analyzing the shape and brightness of the lensed images, ...

Webb was even able to image the nuclear star cluster at the galaxy's ... That's what Webb spotted earlier this year—a galaxy 12 billion light-years away lensed by one just 3 billion light ...

Views of a massive galaxy cluster Abell 2256 have been captured by NASA’s Chandra X-ray Observatory, ESA’s XMM-Newton and ...

What can heat distribution within galaxy clusters, which often consist of hundreds to thousands of galaxies, teach astronomers about their formation and evolution? This is what a recent study ...

Initially, the astronomer who first made note of this fuzzy-looking glowing cluster thought it might be a nebula. But it’s ...

Japanese astronomers have presented new results of observations that suggest an unidentified X-ray source designated AX ...

The XRISM science team, including members of Nagoya University, has explained how galaxy clusters maintain their heat despite emitting X-rays, which typically have a cooling effect on the hot gas.

These clouds of radio energy are "radio relics" resulting from powerful shockwaves surging through the hot gas that fills the space amid a galaxy cluster. Credit: Kamlesh Rajpurohit et al / https ...
