A star in the heart of Omega Centauri has been tracing a slow, inexplicable arc for over two decades — not because it was going anywhere unusual, but because something invisible and massive was ...

The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, ...

The surprise in RCP 28 To understand the jaw-dropping cosmic event, we need to remember that astrophysicist Pieter van Dokkum from Yale University, along with his team, was observing the dwarf galaxy ...

Add Yahoo as a preferred source to see more of our stories on Google. The first of 10,000 missing black holes in the Omega Centauri globular cluster has been found thanks to teamwork by the Hubble and ...

Using NASA's Hubble Space Telescope and Chandra X-ray Observatory, astronomers have hunted for "wandering" black holes drifting through dwarf galaxies. The discovery of these rogue black holes in such ...

Scientists have reconstructed the probable history of RBH-1, the first convincing candidate for the role of a supermassive ...

Using nearly eight hours of observations from JWST’s NIRSpec instrument, the researchers mapped the movement of gas deep ...

Almost 40 years into its journey, Hubble Space Telescope is still racking up scientific discoveries with considerable skill. Recently celebrating its 36th year in continuous operation, Hubble Space ...

Astronomers used the Hubble and James Webb space telescopes to find a stellar black hole in a globular cluster roughly 18,000 light-years away from Earth. Credit: ESA / NASA / M. Häberle / J.

Scientists think a massive object is gravitationally pulling on the stars within Omega Centauri, keeping them close to its center. From the motions of the stars, they estimate it has a mass of at ...
