Black Hole

An image of a black hole surrounded by matter. Does the secret of quantum gravity lie around these cosmic titans too? (Image credit: Robert Lea (created with Canva)) The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black…

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the satellites we use for navigation, communication and Earth observation every day. But you might be surprised to learn that making these measurements – using the science of geodesy –…

Astronomers have uncovered a vast cloud of energetic particles -- a 'mini halo' -- surrounding one of the most distant galaxy clusters ever observed, marking a major step forward in understanding the hidden forces that shape the cosmos. The mini-halo is at a distance so great that it takes light…

AI’s promise is undeniable, but so are its blindsiding security costs at the inference layer. New attacks targeting AI’s operational side are…

This stunning Hubble view of spiral galaxy UGC 11397 captures more than graceful arms and glowing stars—it hides a ravenous supermassive black hole, cloaked in dust but blazing in X-rays. Although invisible in regular light, its energetic core revealed itself as a Type 2 Seyfert galaxy...Read More

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.…
