Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from

A slender crescent moon, Mars and Aldebaran and two sparkling star clusters will create a beautiful predawn scene for early risers on July 11.

Astronomers using archival data from Hubble and supportive observations from Webb have located their first stellar-mass black hole in the star cluster Omega Centauri.

The first of 10,000 missing black holes in the Omega Centauri globular cluster has been found thanks to teamwork by the Hubble and James Webb space telescopes.

Do we really want to play dice with our planet?A series in the Guardian recently declared “it’s time to talk about geoengineering.” So let’s talk about it. And let us start with some simple truths about this cluster of techno-optimistic “quick fixes” which purport to somehow offs

Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young stars that produce ionizing light capable of transforming

University of Miami researchers and collaborators have expanded an offshore reef restoration and coastal resilience project off Miami Beach with the deployment of three 3D-printed SEAHIVE clustered structures.

The subject of today's NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. There are more

Indonesian astronomers have conducted a comprehensive study of an open cluster in the constellation Norma, known as NGC 6134. Results of the new study, available in a research paper published June 23 on the preprint server arXiv, deliver important insights into the properties and

There is a constant war going on in your body. Working against you are viruses and cancer cells growing uncontrollably, threatening your tissues and organs. Fighting on your side are immune cells such as lymphocytes, a type of white blood cell that includes T cells and B cells. B

More than 500,000 stars blaze red, white, and blue in this image from NASA's Hubble Space Telescope, released in celebration of the United States' 250th anniversary. The image showcases Messier 3 (M3), one of the Milky Way galaxy's most massive globular clusters, or spherical col
