Black Hole

Rbkomar/Getty Images The universe is always moving. While we've found evidence of rogue black holes and planets, new research suggests that a passing star could be out there somewhere. Unfortunately, If it were to swing too close to our solar system, it might just send our planet hurtling into the…

The NASA/ESA Hubble Space Telescope shot this image of UGC 11397, a barred spiral galaxy that is hosting an actively growing supermassive black hole. This Hubble image shows UGC 11397, a barred spiral galaxy some 250 million light-years away in the constellation of Lyra. Image credit: NASA / ESA /…

Neutron star collisions have finally been fully simulated, revealing how they ignite cosmic fireworks and create the universe’s heaviest elements. Record-breaking achievement: Scientists led by the Max Planck Institute for Gravitational Physics have completed the longest and most detailed simulation ever of a binary neutron star merger...Read More

The radio emission of Tailed Radio Galaxy, observed at 144 MHz with an angular resolution of 0.34 0d7 0.24 arcseconds, shows a complex and filament-rich structure. In the upper right corner, a close-up of the region centered on the host galaxy is shown, whose nucleus is indicated with a red…

An image of the supermassive black hole at the center of the Milky Way dubbed Sagittarius A* (Image credit: Event Horizon Telescope collaboration) A powerful new technique is poised to revolutionize how astronomers observe black holes, by producing sharp, multicolored images that could reveal their dynamic evolution in real time.…

Black holes are nature’s ultimate shadow dwellers—silent, invisible unless they interact with their surroundings. Some continuously devour gas and dust, glowing eerily as matter spirals inward. Others, however, lie in wait for years, lurking undetected until an unsuspecting star drifts too close. A new study utilizing NASA, ESA, and ground-based…

New research by physicists from the University of Oxford, Johns Hopkins University and the Institute of Astrophysics in Paris shows that collisions between particles free falling from infinity and a disk of material plunging off the retrograde innermost stable circular orbit of a rotating black hole is the unique astronomically…

Black holes are invisible to us unless they interact with something else. Some continuously eat gas and dust, and appear to glow brightly over time as matter falls in. But other black holes secretly lie in wait for years until a star comes close enough to snack on. A new…

The Big Bang is often described as the explosive birth of the universe — a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else — something more familiar and radical at…

An artist's concept of a supermassive black hole with a jet streaming outward at nearly the speed of light. (Image credit: NASA/JPL-Caltech) In the face of eye-watering costs , long construction times and the Trump administration's slashing of federal science funding , physicists have proposed a cheaper alternative to the…
