Astronomer Feryal Özel is one of the pioneers of black hole photography. With two pictures in the album, she explains what we have learned about these gravitational monsters – and what comes next Society 21 June 2022 By Abigail Beall Nabil Nezzar A FEW weeks ago, we got our first look at a portrait of […]
Hours after unveiling the first image of the black hole at the center of the Milky Way, scientists from the Harvard & Smithsonian-led team discussed its significance in an online panel.

Scientists at the University of North Carolina at Chapel Hill, led by faculty-graduate student team Sheila Kannappan and Mugdha Polimera, have found a previously overlooked treasure trove of massive black holes in dwarf galaxies that offer a glimpse into the life story of the supermassive black hole at the center of our own Milky Way […]
The study of black holes has advanced immensely in the past few years. In 2015, the first gravitational waves were observed by scientists at the Laser Interferometer Gravitational-Wave Observatory (LIGO). This finding confirmed what Einstein predicted a century before with General Relativity and offered new insight into black hole mergers. In 2019, scientists with the
(CNN) — Millions of elusive black holes hide in plain sight across the Milky Way galaxy, only giving away their presence occasionally through bursts of X-ray light when they feed on stars. Astronomers have been able to pin down the locations of eight rare pairings of black holes and the stars orbiting them, thanks to […]
An illustration of what GNz7q might have once looked like. Though they’re extremely rare, examples of both dusty starburst galaxies and luminous quasars have been detected in the early universe. The team believes that GNz7q could be the “missing link” between these two classes of objects. ESA/Hubble, N. Bartmann Some 13.8 billion years ago, the universe […]
Understanding phenomena of black holes in ‘Black Hole Survival Guide’ABC News’ Linsey Davis speaks with astrophysicist Janna Levin, author of “Black Hole Survival Guide,” breaking down all the fundamentals of black holes and how they are seen in the universe. Source link
Though scientists know there’s a supermassive black hole at the center of most galaxies, they can’t explain how the gravitational giants formed. But physicists Hooman Davoudiasl, Peter Denton, and Julia Gehrlein of the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory in New York have determined one plausible theory: a “cosmological phase transition” of ultralight […]
