Supermassive black holes are believed to exist at the centre of most galaxies, including our Milky Way. However, in certain cases, two such black holes are thought to orbit one another, forming binary systems. These gravitationally bound pairs could provide significant insights into the dynamics of galaxy formation and the behaviour of space-time. Detecting them, […]
Here’s a quick look at some of the astronomy news that’s come out in December 2024. An artist’s rendering shows the Thirty Meter Telescope (TMT) on the left and the Giant Magellan Telescope (GMT) on the right, both featuring their laser guide stars activated.US-ELTP (TIO / NOIRLab / GMTO) Fate of U.S. Megatelescopes Undecided A […]
Mike Ehrmann/Getty Images Tigers Woods told reporters on Friday that his 15-year-old Charlie Woods has already beaten him over nine holes of golf— and that he believes an 18-hole defeat is coming eventually. “He beat me for nine holes,” Woods said, per Doug Ferguson of the Associated Press. “That day is coming. I’m just prolonging […]

However, modeling has shown that it is difficult to scatter enough stars toward the black holes to solve the final-parsec problem. Alternatively, each black hole might have a small disk of gas around it, and these disks might draw in material from a wider disk that surrounds the empty region carved out by the holes. […]
Artist’s representation of a galaxy with a brilliant quasar at its centre NASA, ESA and J. Olmsted (STScI) Space-time, the so-called fabric of physical reality, may be made of tiny, discrete pieces stitched together. A preliminary analysis of the way matter orbits quasars suggests we could find evidence of this cosmic quilt in the universe’s […]
A large open hole is seen in the Kuskokwim River in front of the community of Akiak on Nov. 18, 2024. (Courtesy Mark Leary/Bethel Search and Rescue) While the Kuskokwim River is starting to freeze, open water and thin ice are widespread along the well-traveled mainstem of the lower river, as well as around the […]
A recent cosmic census has revealed an unexpected threefold rise in active black holes within dwarf galaxies, creating the most extensive database of intermediate-mass black holes recorded to date. This survey, conducted with the Dark Energy Spectroscopic Instrument (DESI) at the Mayall Telescope in Arizona, identified over 2,500 black holes in dwarf galaxies—more than triple […]
Astronomers are watching two unusual black holes, each presenting phenomena that challenge current understanding of these cosmic giants. One, a “serial killer” black hole, is about to devour its second star within five years, while the other, part of the newly discovered triple system V404 Cygni, has disrupted long-held theories of black hole formation. The […]
Scientists have strengthened the potential connection between dark energy and black holes. New research suggests that as more black holes were born in “little Big Bang reverse replays” in the 14.6 billion-year-old cosmos, the strength of dark energy grew to dominance and continues to change to this day. Dark energy is the placeholder name given […]
