Black Holes

How do astronomers find the darkest objects in the universe?

Domain walls, long a divisive topic in physics, may be ideal explanations for some bizarre cosmic quirks

A black hole weighing as much as 33 suns lurks a mere 2,000 light-years away from our solar system

As the Event Horizon Telescope pursues ambitious upgrades, the project’s latest results reveal the magnetic fields around our galaxy’s supermassive black hole

Polarized light from Sagittarius A*, our galaxy’s supermassive black hole, shows swirling magnetic fields that may hint at the presence of an unseen jet

The quasar, as bright as 500 trillion suns, has evaded astronomers for over 40 years because of its incredible luminosity

The Laser Interferometer Space Antenna (LISA) will open a new era in astronomy that brings scientists to the brink of studying gravitational waves from the beginning of time

The earliest active supermassive black hole ever seen offers clues on how these enigmatic objects first formed

A new simulation shows black holes ripping apart and consuming their accretion disk in a matter of months, which may explain why some quasars quickly brighten and dim

Physicist John Cardy and his colleague just won the 2024 Breakthrough Prize in Fundamental Physics. We spoke with Cardy about conformal field theory, 2D black holes and coffee filters

Black holes in the extraordinarily distant cosmos are out of tune with their host galaxies, offering insights into their formation

Before leading the Manhattan Project, J. Robert Oppenheimer co-authored a paper explaining that the most massive stars must eventually become what we would now call a black hole
