Astronomers have discovered a previously hidden "cosmic fuel tank" in an infant cluster of forming galaxies. This vast reservoir of cool molecular gas is found in the protocluster known as SPT2349-56, ...

Astronomers using the James Webb Space Telescope have discovered a rare jellyfish galaxy 8.5 billion light-years from Earth, ...

The NASA/ESA Hubble Space Telescope has identified thousands of more than 5 billion years old globular clusters in the Virgo cluster of galaxies. One of the results of these discoveries led ...

Astronomers have identified what appears to be an unusually distant candidate “jellyfish” galaxy, a strange object trailing a one-sided tail of newborn stars that appears consistent with ram-pressure ...

Astronomers using the James Webb Space Telescope have spotted the most distant “jellyfish galaxy” ever seen — a cosmic oddity ...

Galaxies like our Milky Way with its 100 billion stars are usually not found in isolation. In the Universe today, 13.8 billion years after the Big Bang, many are in dense clusters of tens, hundreds or ...

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 ...

Astronomers have explained how a galaxy cluster maintains its heat, despite emitting X-rays that cool the hot gas at its center. The group discovered the existence of a fast-moving, high-temperature ...

Dark galaxies are believed to have very few stars, if any at all, according to CNN. In the case of CDG-2, a preliminary ...

Each coloured circle depicts a galaxy group or cluster. The richest galaxy clusters are marked in red; these are the richest galaxy clusters in the Hercules and Leo superclusters. The side panels show ...

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. By ...
