This one-million-year-old star-forming region contains thousands of new stars and hundreds of planetary mass objects floating freely in the nebula, not orbiting stars. A groundbreaking study published ...

Scientists have released a new study that catalogues the universe by mapping huge clusters of galaxies. These clusters are some of the largest known objects in the universe — and they can help ...

The biggest objects in the universe are clusters of galaxies, such as the supercluster we live in right now - and including Abell 370, which was captured in a sprawling glittery space-scape by the ...

Newly discovered Quipu, a superstructure in which galaxies group together in clusters and clusters of clusters, is the largest known structure in the universe in terms of length, scientists claim.

Warm mid-August summer nights offer prime conditions for spotting three magnificent star clusters visible to northern-hemisphere skywatchers in the coming months. Star clusters are gravitationally ...

A study published in Science Advances sheds new light on the mysterious origins of free-floating planetary-mass objects (PMOs)—celestial bodies with masses between stars and planets. Led by Dr. Deng ...
