A weird problem astronomers have is finding monster black holes. It's a common misconception that black holes are nature's ultimate garbage compactors. Toss something in, and it's gone. Bloop! But that's not always the case.

I recently wrote about the possibility that two huge black holes collided and merged in the center of the Andromeda Galaxy, sowing chaos. As you might expect, though, they need not collide to be trouble. They're supermassive black holes. Trouble is everywhere they are. What might surprise you, though, is just how they can create discord. And this one I love: They're monsters. They roar.

A growing number of galaxies seem to be bereft of the mysterious substance, posing fresh challenges for some of cosmology’s most cherished theories

Galaxies aren't alive. It can be a useful metaphor — they are born, they live, they die — but animism shouldn't be used literally with them. And yet, some have a double helix. Shades of DNA! In this case the double helix is quite literal, though it's not a genetic blueprint, of course. Still, studying it can reveal much about what happens at the galaxy's heart, where a dark monster rages and spews.

Astronomers completed a 40-hour long observation of an ultra-diffuse dwarf galaxy and discovered no traces of dark matter.

Astronomers using NSF's Karl G. Jansky Very Large Array have captured unprecedented high-fidelity radio images of a jet of material propelled from the core of the giant elliptical galaxy Messier 87. Messier 87 is an elliptical galaxy located some...

The first black hole that we photographed has been caught shooting out a jet that is shaped similar to DNA or a cork screw.

Stunning new images released by the European Southern Observatory (ESO), show several stars moving around their orbit of the Milky Ways black hole, called Sagittarius A*.

Ylva Pihlström, a professor in the Department of Physics and Astronomy, recently was awarded a three-year, $564,000 grant from NASA to continue research that she started as part of her 2017 Women In STEM Award. The work, set to begin in January 2022,...

The Milky Ways black hole, Sagittarius A*, burps a blowtorch-like jet out into space through this leak, researchers from the University of North Carolina have revealed.
