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,…

An artist's illustration of three black holes. (Image credit: Shutterstock) Astronomers have used the Dark Energy Spectroscopic Instrument (DESI) to discover a treasure trove of black holes, many of which are rare "missing links" in the cosmic monsters' evolution. The search, which swept across 410,000 galaxies, identified a staggering 2,500…

Astronomers using the Dark Energy Spectroscopic Instrument (DESI) on NSF’s Nicholas U. Mayall 4-m telescope at Kitt Peak National Observatory, a program of the NOIRLab, have compiled the largest sample ever of dwarf galaxies that host an actively feeding black hole, as well as the most extensive collection of intermediate-mass…

Scientists using the Dark Energy Spectroscopic Instrument (DESI) have completed two major tasks. They’ve compiled the largest ever sample of dwarf galaxies (systems contain up to a mere several billion stars, compared to the Milky Way’s estimated 2 billion to 400 billion) that host an actively feeding black hole. They’ve…

The accretion disk orbiting Sagittarius A* is emitting a constant stream of flares with no periods of rest, according to an analysis of new data from the NASA/ESA/CSA James Webb Space Telescope; while some flares are faint flickers, lasting mere seconds, other flares are blindingly bright eruptions, which spew daily;…

Astronomers using NASA’s James Webb Space Telescope (JWST) have taken a detailed look at the supermassive black hole at the center of our Milky Way, called Sagittarius A*. They found that the swirling disk of gas and dust around it constantly emits flares. These flares vary in brightness and duration:…

Black holes have such strong gravity that not even light can escape. They are very dense and have intense gravitational forces. Scientists think primordial black holes (PBH) might make up some or all of the Universe’s dark matter. If there are enough PBHs, they could have various effects. Researchers have…

WASHINGTON: NASA's James Webb Space Telescope is providing the best look yet at the chaotic events unfolding around the supermassive black hole at the centre of our Milky Way galaxy, observing a steady flickering of light punctuated by occasional bright flares as material is drawn inward by its enormous gravitational…
