black holes

Astronomers investigated an active supermassive black hole at the heart of Perseus A using the Event Horizon Telescope, spotting an epic battle between gravity and magnetism.

ESO 420-G013 is a face-on spiral galaxy with an almost perfectly round disk and an active black hole lighting up its starry guts.

Scientists using the eROSITA X-ray telescope have released a trove of data that reveals more than 900,000 objects in space, including 700,000 supermassive black holes and other 'exotic' objects.

Observations made by Chile's ALMA telescope have revealed a gigantic quasar quenching a galaxy's star formation — a first-of-its-kind observation in the early universe.

The new LISA gravitational wave detector, which will be launched into orbit in 2035, promises to detect cosmic collisions from the earliest moments after the Big Bang.

The presence of supermassive black holes in the earliest epochs of the universe has scientists stumped — but repeated explosions from tiny black holes may offer an explanation.

The most sensitive image of a globular cluster, a tightly packed ball of ancient stars, has revealed a strange radio signal that could be a black hole.

Many models of the universe predict the existence of countless invisible strings stretching across space. New research finds a way these strings might snap — and how we could feel the fallout.

A study suggests primordial black holes may make planets and moons near us wobble. If measured experimentally, this will provide the first concrete proof such objects exist.

Aliens made headlines in 2023, but are we really any closer to finding life beyond Earth? A recap of the best new evidence, and other remarkable stories from the year in space.
