Webb telescope data confirm a supermassive black hole fleeing its galaxy, carving a 200,000 light-year wake of new stars.

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth&rsquo ...

Observations of a distant quasar reveal that supermassive black holes may suppress star formation across intergalactic distances.

For a few brief nights each year, you get a rare chance to watch a monster blink. The Event Horizon Telescope collaboration ...

Runaway black holes have moved from theoretical oddity to observed reality, and the picture they paint is as unsettling as it is awe inspiring. Instead of sitting quietly at galactic centers, some of ...

A massive star in the nearby Andromeda galaxy has simply disappeared. Some astronomers believe that it's collapsed in on itself and formed a black hole.

Supermassive black holes rarely travel alone. Most large galaxies hide one at the center, and when galaxies collide, the two ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Scientists created “sonic black holes” in the lab to mimic how real black holes trap light — except these trap sound. Then they ran the experiment again and again… 97,000 times. What showed up in the ...

Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At 225 solar masses, the black hole resulting from the merger ...

What can astronomers learn from observing black holes that suddenly wake up? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers ...

Gravitational waves—ripples in space-time caused by violent cosmic events—travel at the speed of light in every direction, eventually fading out like ripples in water. But some events are so ...
