Black Holes

What do black holes look and sound like? How do they form? And what happens when a person falls into one? The answers to most any black hole question.

This artist’s concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Researchers will mine data from NASA’s Nancy Grace Roman Space Telescope, which will survey the same areas of the sky every few days, to identify kilonovae. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

The universe may die sooner than expected

A bright disc of purplish, white and gold lines surrounds a black ellipse-shaped area, that looks like a hole in space. A ball of shining material pierces through the disc; an eruption of bright white-to-gold rays encircles the small hole in the disc provoked by the passage of the shining ball

The Giant Metrewave Radio Telescope imaged these giant radio jets stretching 6 million light-years across with an enormous supermassive black hole at the heart of spiral galaxy J23453268-0449256. Could this cosmic anomaly hint at the future of our own Milky Way galaxy? Image via Bagchi and Ray et al/ Giant Metrewave Radio Telescope/ Royal Astronomical Society/

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.

Fastest-growing black hole eats the equivalent of one sun a day

Astronomers found the most distant black hole ever detected in X-rays (in a galaxy dubbed UHZ1) using the Chandra X-Ray Observatory and the James Webb Space Telescope. X-ray emission is a telltale signature of a growing supermassive black hole. This result may explain how some of the first supermassive black holes in the universe formed. These images show the galaxy cluster Abell 2744 that UHZ1 is located behind, in X-rays from Chandra and infrared data from JWST, as well as close-ups of the black hole host galaxy UHZ1.

Astronomers used dead stars to detect a new form of ripple in space-time

Astronomers studying a powerful gamma-ray burst (GRB) with the International Gemini Observatory, operated by NSF’s NOIRLab, may have observed a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.
