Black Holes

The supermassive black hole at the heart of the galaxy M87 is coming into sharper and sharper focus.

NASA's long-serving Hubble Space Telescope is seeing double after detecting two rare pairs of quasars nestled within galactic collisions that occurred 10 billion years ago.

Evidence of collisions between black holes and neutron stars suggests dark matter might consist of concentrations of primordial black holes.

In 2017, astronomers witnessed the birth of a black hole for the first time.

Light coming from an explosion in the early universe has illuminated a black hole that astronomers think could expand their understanding of how the celestial objects form.

Astrophysicist Andrea Ghez has spent her scientific career peering at the center of the Milky Way, trying to see the invisible.

A supermassive black hole is racing across the universe at 110,000 mph (177,000 km/h), and the astronomers who spotted it don't know why.

A space telescope might have spotted one of the most distant supermassive black holes spurting an X-ray jet.

The hypothetical Planet Nine may not be a planet but rather a small black hole that might be detectable from the theoretical radiation emitted from its edge, so-called Hawking radiation.

A newly discovered quasar from the early universe is the most distant found to date that's shooting out powerful radio jets.

Black holes may not be black or holes, a new theory proposes.

Like mad scientists, researchers are creating miniature black holes in their laboratories. Their mission? To see if a mysterious form of radiation predicted by Stephen Hawking exists.

A ghostly particle that smashed into Antarctica in 2019 has been traced back to a black hole tearing apart a star while acting like a giant cosmic particle accelerator, a new study finds.

New evidence suggests the first known black hole is bigger than previously thought, which may force scientists to reconsider their understanding of how giant stars give rise to black holes.

The globular cluster NGC 6397, a conglomeration of stars about 7,800 light-years from Earth, likely harbors a clump of small black holes at its heart, a new study reports.

The upcoming documentary "Black Holes: The Edge of All We Know" explores the many meanings of black holes and the Event Horizon Telescope's pioneering photo. See a trailer for the film here.

In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.

The universe may be filled with "mirror" particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black holes.
