Astronomers working with the Hubble Space Telescope have identified a nearly invisible galaxy in the Perseus Cluster that appears to consist almost entirely of dark matter. Designated Candidate Dark ...

The universe is overrun with dark matter, outweighing the ordinary stuff that stars and planets are made of five-to-one. But ...

A stronomers report the discovery of a truly incredible object. They are calling it Candidate Dark Galaxy-2 (CDG-2), a ...

A galaxy made of 99.94% to 99.98% dark matter immediately challenges and updates models for how dark matter works. It also sheds light on how the universe arrived at the large-sca ...

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 ...

A globular cluster is a spherical collection of stars. Globular clusters are very tightly bound by gravity, giving them their spherical shapes and high concentrations of stars toward their centers.

NASA’s Hubble Space Telescope has uncovered what astronomers are reporting as the dimmest stars ever seen in any globular star cluster. Globular clusters are spherical concentrations of hundreds of ...

Globular clusters are ancient, spherical groups of stars that are often as old as the galaxies they orbit. The stars in a globular cluster orbit the center of mass of the cluster, and the angular ...

NASA's Hubble Space Telescope snapped a pair of "dazzlingly different" images of a brilliant star cluster some 160,000 light years away. Globular cluster NGC 1850, in the constellation Dorado, is ...

The Hubble Space Telescope finessed the light beaming in from outside our galaxy, and the result is a fabulous image where individual stars are seen in a big embrace. When thousands or even millions ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. An international team of astronomers have created the most ...

Hubble recently captured a dazzling image of the heart of globular cluster Terzan 9, a bright ball of stars 23,000 light years away. Globular clusters are tightly packed groups of tens of thousands — ...
