Black Hole

Observations have found black holes spanning 10 orders of magnitude in mass across most of cosmic history. The assembly of stellar and supermassive black hole (SMBH) mass in galaxies can help to diagnose the origins of locally observed correlations between SMBH mass and stellar mass.   A team of researchers led…

A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help…

(Image credit: NASA/JPL-Caltech) Supermassive black holes could be the engines driving the expansion of the universe, according to research that proposes a solution to "one of the biggest problems in cosmology."  By comparing supermassive…

A lab-made black hole is beyond current technology but could be possible one day Credit: Jennifer Lamberth/EyeEm/Getty Images In the popular imagination, black holes are voracious monstrosities gulping down anything in their vicinity. That is why there are occasional worries that physicists might accidentally or intentionally create one, perhaps inside a…

Clues to a black hole's origins can be found in the way it spins, which is especially true for binaries — when two black holes circle close together before merging. The spin and tilt of the respective black holes just before they merge can reveal whether they arose from a…

In this illustration, light from a smaller black hole (left) curves around a larger black hole and forms an almost-mirror image on the other side. The gravity of a black hole can warp the fabric of space itself, such that light passing close to the black hole will follow a…

The cosmos seems to have a preference for things that are round. Planets and stars tend to be spheres because gravity pulls clouds of gas and dust toward the center of mass. The same holds for black holes — or, to be more precise, the event horizons of black holes…
