Black Hole

Mysterious red galaxies from the universe’s dawn may trace back to rare, slow-spinning dark matter halos, creating extreme conditions that sparked rapid star or black hole growth. (Artist’s concept.) Credit: SciTechDaily.com Astronomers may have uncovered the secret behind the mysterious “little red dots” seen by the James Webb Space Telescope.…

In his new paper, Professor Jonathan Tan, an astrophysicist at the University of Virginia and the Chalmers University of Technology, proposes that Population III.1 supermassive stars were progenitors of supermassive black holes in the early Universe; high energy photons from the stars ionized the surrounding hydrogen gas far out into…

An artist's illustration of the black hole IGR J17091‑3624, showing material swirling around its inner region, called the corona, which emits bright X-rays detected by NASA's Imaging X-ray Polarimetry Explorer (IXPE). (Image credit: NASA/Caltech-IPAC/Robert Hurt) A black hole’s bizarre "heartbeat" is forcing astronomers to reconsider how these cosmic heavyweights behave.…

An artist's impression of the events leading up to supernova SN 2023zkd, which likely occurred when a star attempted to swallow a nearby black hole. Here, the star's shape is stretched by the black hole's massive gravitational forces. (Image credit: Melissa Weiss/CfA) Scientists may have spotted a never-before-seen kind of…

A view of The Cosmic Horseshoe and its gravitational lens, in which an ultramassive black hole appears to be lurking. (Image credit: NASA/ESA) The massive " Cosmic Horseshoe " galaxy system likely hosts a colossal black hole measuring 36 billion times the mass of our sun — one of the…

Artificial intelligence has helped astronomers observe what may be the first known case of a star exploding while interacting with a black hole, a new study reports. (Image credit: Melissa Weiss/CfA) Astronomers have observed what may be the first known case of a massive star exploding while interacting with a…

An artist representation of the CAPERS-LRD-z9 galaxy (Image source: Erik Zumalt and The University of Texas at Austin) A team of astronomers has discovered a black hole that possibly dates back as early as 13.3 billion years ago — only 500 million years after the Big Bang. This discovery could…

In a new paper published in the journal iScience, an astrophysicist from Fudan University discusses the possibility of sending a nanocraft to a black hole at 20-25 light-years from Earth to test the nature of the compact object and fundamental physics in strong gravitational fields. Black holes are the sources…
