Scientists waited ages to find a 'missing link' black hole — then stumbled upon 2
By Robert Lea published
A missing link black hole that sits in the mass gap between stellar-mass black holes and supermassive black holes is "parked" right by the Milky Way's central black hole, Sagittarius A*.

Study finds black holes made from light are impossible — challenging Einstein's theory of relativity
By Andrey Feldman published
New theoretical research finds that it's impossible to form a black hole with the energy of light particles alone, poking a hole in Einstein's theory of general relativity.

Supermassive black holes provide 'hearts and lungs' that help galaxies live longer
By Robert Lea published
The universe would be filled with zombie galaxies and dead stars if not for supermassive black hole-powered 'hearts and lungs' that help slow star formation.

In the last 25 years, black hole physicists have uncovered the unimaginable
By Robert Lea published
Over the last 25 years, black hole physics has experienced something of a revolution.

Hubble Space Telescope finds closest massive black hole to Earth — a cosmic clue frozen in time
By Robert Lea last updated
The Hubble Telescope has discovered a black hole "frozen in time" that's also the closest massive black hole to Earth.

James Webb Space Telescope sees an ancient black hole dance with colliding galaxies
By Robert Lea published
Using the James Webb Space Telescope, astronomers have witnessed the dramatic dance between a supermassive black hole-powered quasar and merging galaxies less than a billion years after the Big Bang.

Quasars are 'cosmic signposts' pointing to rare supermassive black hole pairs
By Robert Lea published
New research suggests that galaxies with quasars at their active hearts are seven times more likely to harbor elusive supermassive black hole binary paintings than other galaxies.

Watch a supermassive black hole trap a 'fluffy' disk in this simulation
By Sharmila Kuthunur published
A new computer simulation flies through tangled galaxies and zooms in on a black hole to dissect how these voids feats on surrounding matter.

Weird physics at the edges of black holes may help resolve lingering 'Hubble trouble'
By Robert Lea published
The expansion of the universe may not be accelerating at the edges of black holes. If this is the case at all event horizons, this may explain "Hubble tension," and the worst prediction in physics.

Missing Milky Way black holes are bad news for this dark matter theory
By Robert Lea published
After 20 years watching stars in the Large Magellanic Cloud for hints of a phenomenon predicted by Einstein, scientists throw doubt on the connection between ancient black holes and dark matter.
