Black Hole

Space is home to mysterious giants—black holes that have grown larger and faster than scientists expect. The formation of these behemoths may share a common root with another cosmic mystery, dark matter, according to a recent study. Astrophysicists know that violent deaths of stars can form black holes typically up…

Black holes form when massive stars run out of fuel and implode Scientists say they have solved one of the biggest paradoxes in science first identified by Prof Stephen Hawking. He highlighted that black holes behave in a way that puts two fundamental theories at odds with each other. Black…

With 90 detections now under our belt, gravitational waves are solving riddles about the evolution of galaxies and missing black holes – and they could soon give us a glimpse of dark matter Physics 16 March 2022 By Stuart Clark Ollie Hirst IN A darkened room in Sweden, beneath a…

The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question in astrophysics. Brookhaven National Laboratory theoretical physicists Hooman Davoudiasl, Peter Denton, and Julia Gehrlein have developed a model to explain the formation of these…

An audit of NASA's infosec preparedness against insider threats has warned it faces "serious jeopardy to operations" due to lack of protection for unclassified information. A Monday report found that NASA has done well, as required, in its efforts to defend and prevent insider threats to classified information – stuff…

astrophysicsBy Charlie WoodMarch 14, 2022 Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed. Astronomers found evidence for hidden black holes in these dwarf galaxies, among others.

Nothing can escape a black hole, not even light. In simple words, they are the regions of space with an extremely strong gravitational field. But we can see the effects black holes have on the space around them.  Black holes remain one of the most mysterious objects in-universe. Understanding them…

A team of researchers from Purdue University and other institutions have discovered a supermassive black hole binary system, one of only two known such systems. The two black holes, which orbit each other, likely weigh 100 million suns each. One of the black holes powers a massive jet that moves…

An international team of physicists from RIKEN, Cornell University and the University of California, Santa Barbara, has used a new spacetime geometry with a wormhole-like structure to show that information is not necessarily irretrievably lost from evaporating black holes.

In 2020, the X-ray satellite eROSITA revealed two gigantic bubbles extending to 80° above and below the center of our Milky Way Galaxy. The morphology of these ‘eROSITA bubbles’ bears a remarkable resemblance to the Fermi bubbles previously discovered by NASA’s Fermi Gamma-ray Space Telescope and its counterpart — the…
