Black Hole

Black hole singularities — theoretical points of infinite density at the centers of the cosmic monsters — defy physics. New tweaks proposed to Einstein’s relativity may do away with them at last. (Image credit: Adis Resic via Pixabay) Theoretical physicists have proposed a potential solution to one of the most…

A Hubble Space Telescope image of LRG 3-757, known as the "Cosmic Horseshoe". (Image credit: NASA, ESA) Astronomers have discovered an enormous black hole the size of 36 billion suns lurking within the "Cosmic Horseshoe." The behemoth object is one of the largest black holes ever detected. First discovered in…

STAR STUDDED: South Africa’s Switzerland-based CERN physicist and virtual tour commentator, Dr Claire Lee, next to the Large Hadron Collider (LHC) built into a tunnel 100m below ground level in Geneva, that helps study the formation of the universe. Lee presented a virtual tour of the facility to U3A members…

New research from a team at the Harvard Center for Astrophysics suggests that the Large Magellanic Cloud, a dwarf galaxy neighboring the Milky Way, hosts a gravitational structure hundreds of thousands of times the mass of the sun: a potential supermassive black hole. The most widely accepted theory of galactic…

At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these enigmas, we take what we know about space, time, gravity and quantum mechanics and apply it to a place where all of those things simply break…

These flares are bright enough to shine across 26,000 light-years of space. By Elisha Sauers Elisha Sauers writes about space for Mashable, taking deep dives into NASA's moon and Mars missions, chatting up astronauts and history-making discoverers, and jetting above the clouds. Through 17 years of reporting, she's covered a…

An illustration shows a spinning black hole (Image credit: Robert Lea (created with Canva)) Black holes may leak more energy to their surroundings than previously suspected — and the faster these voids spin, the more efficient this energy extraction seems to be. With this in mind, a team of scientists…

This artist's concept shows Sagittarius A*, a supermassive black hole at the center of the Milky Way galaxy, surrounded by a swirling accretion disk of hot gas. Flaring hot spots that resemble solar flares are seen in the disk. NASA, ESA, CSA, Ralf Crawford (STScI)/NASA.gov hide caption toggle caption NASA,…
