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, ...

Just as people of the same age can vary greatly in appearance and shape, so do collections of stars or stellar aggregates. New observations from the NASA/ESA Hubble Space Telescope suggest that ...

New research demonstrated a possible formation mechanism of intermediate-mass black holes in globular clusters, star clusters that could contain tens of thousands or even millions of tightly packed ...

Gravitational lensing exposed a distant protocluster once seen as a faint smudge, revealing eleven dusty star-forming galaxies through combined ALMA and NSF VLA observations.

Christmas-themed imagery knows no bounds, not even in space. NASA has drawn comparison between a celestial formation and a holiday wreath, referring to the recently spotted star and dust cloud cluster ...

On the left, an artist’s impression of a globular cluster near its birth, hosting extremely massive stars with powerful stellar winds that enrich the cluster with elements processed at extremely high ...

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 ...
