"Death Star" Black Holes Can Swivel Their Million Light-Year Long Plasma Beams

Heavyweight black holes sometimes topple over on their sides, according to X-ray and radio observations of the jets these black holes power.

Did This Black Hole Form Without a Supernova?

Some massive stars may collapse completely into black holes — without the fanfare of a supernova.

Three panels are shown showing an increasingly small area of the PRIMER galaxy field. The first image shows a large field of galaxies on the black background of space. The second image shows a smaller region from this field, revealing the galaxies in closer detail, appearing in a variety of shapes and colours. The final image shows the ZS7 galaxy system, revealing the ionised hydrogen emission in orange and the doubly ionised oxygen emission in dark red.

Black Holes in Early Universe Are Too Big

JWST observations of the universe as it was 12 to 13 billion years ago indicate that the black holes at the centers of small, early galaxies were more massive than expected.
