Each black hole's mass is more than 800 million times that of our sun. As the two gradually draw closer together in a death spiral, they will begin sending gravitational waves rippling through space-time.

The Event Horizon Telescope (EHT) -- a planet-scale array of eight ground-based radio telescopes forged through international collaboration -- was designed to capture images of a black hole.

Telling Black Holes Apart

One of the most fundamental predictions of Einstein's theory of relativity is the existence of black holes.

For the first time ever, astronomers at The University of New Mexico say they've been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth - a discovery more than a decade in the making.

Seeing Black Holes and Beyond

A powerful new array of radio telescopes is being deployed for the first time this week, as the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile joins a global network of antennas poised to make some of the highest resolution images that astronomers have ever obtained.

Monster black holes sometimes lurk behind gas and dust, hiding from the gaze of most telescopes.

Black Holes Sing in X-Rays

Supermassive black holes in the universe are like a raucous choir singing in the language of X-rays

New calculations predict that the Laser Interferometer Gravitational wave Observatory (LIGO) will detect approximately 1,000 mergers of massive black holes annually once it achieves full sensitivity early next decade.

Using data from NASA's Great Observatories, astronomers have found the best evidence yet for cosmic seeds in the early universe that should grow into supermassive black holes.

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle.

Entangled by gravity and destined to merge, two candidate black holes in a distant galaxy appear to be locked in an intricate dance.

Dartmouth astrophysicists and their colleagues have not only proven that a supermassive black hole exists in a place where it isn't supposed to be, but in doing so have opened a new door to what things were like in the early universe.

Black Holes Don't Make a Big Splash

Throughout our universe, tucked inside galaxies far, far away, giant black holes are pairing up and merging. As the massive bodies dance around each other in close embraces, they send out gravitational waves that ripple space and time themselves, even as the waves pass right through our planet Earth.
