Black holes are not black but have a radiation spectrum that is very similar to that of a black body makes black holes an ideal laboratory to investigate the interplay between quantum mechanics, gravity, and thermodynamics.
Globular cluster is older than 10 billion years, like most other globular clusters, meaning that it formed in the earliest phases of galaxy formation. It is about 10 times less massive and five times more extended than a typical globular cluster and in the final stages of dissolution.
New York: A new view of a supermassive black hole marks the first time astronomers have captured and mapped polarisation, a sign of magnetic fields, so close to the edge of a black hole. Images released by the Event Horizon Telescope (EHT) collaboration revealed how the black hole, some 55 million light-years away at the […]
Washington: Researchers have discovered a galaxy that has been managing to survive a black hole’s hunger by continuing to birth new stars, about 100 Sun-sized stars a year. The discovery from NASA’s telescope on an airplane, the Stratospheric Observatory for Infrared Astronomy (SOFIA), can help explain how massive galaxies came to be, even though the […]
New York: Researchers have detected a strange repeating rhythm of Fast Radio Bursts (FRBs) emanating from an unknown source outside our galaxy, 500 million light-years away. Fast radio bursts, or FRBs, are short, intense flashes of radio waves that are thought to be the product of small, distant, extremely dense objects, though exactly what those […]
London: In a historic feat, astronomers announced on Wednesday that they have captured the first-ever image of a black hole in a distant galaxy — the biggest tribute to the late Stephen Hawking who theorised about the existence of black holes emitting radiation in the universe. The image — taken by a network of eight […]
London: In a bid to better understand how black holes behave, researchers have created a virtual reality (VR) simulation of Sagittarius A, the black hole at the centre of our galaxy. The researchers used recent astrophysical models of Sagittarius A to create a series of images that were then put together to create a 360 […]
