Black Hole

According to Einstein’s theory of gravity, black holes have only a small handful of distinguishing characteristics. Quantum theory implies they may have more. Now an experimental search finds that any of this extra ‘hair’ has to be pretty short. Introduction According to Albert Einstein’s general theory of relativity, the behavior…

NASA NIAC is developing X-ray imaging in crucial wavelengths that will be a million times better for observing key aspects of a super massive black hole. We still know very little about giant supermassive black holes (SMBH). After 30 years of study, we don’t know precisely how these objects produce…

Astronomers at the Center for Astrophysics | Harvard & Smithsonian have proposed a new explanation for some of the universe's most puzzling early galaxies, nicknamed "little red dots." In the study, published in The Astrophysical Journal Letters, Authors Fabio Pacucci and Abraham (Avi) Loeb suggest that these galaxies are the…

Astronomers used a UC Santa Cruz-led AI system to detect a rare supernova, SN 2023zkd, within hours of its explosion, allowing rapid follow-up observations before the fleeting event faded. Evidence suggests the blast was triggered by a massive star's catastrophic encounter with a black hole companion, either partially swallowing the…

Policy can seem like opening a blind box: you’ll get something, but probably not what you want. Jim Chalmer’s economic roundtable was no different. Every option is on the table, yes, but what we’ll get is as unknown as what is driving the Labubu craze.  First, the positives. Holding the roundtable is at…

Topline Astronomers have detected what may be the most massive black hole ever observed. It was found within what’s known as the Cosmic Horseshoe galaxy — one of the most massive galaxies known — which is so large it distorts spacetime into a near-ring of light. The Cosmic Horseshoe gravitational…

Proceedings of the National Academy of Sciences, Volume 122, Issue 34, August 2025. SignificancePowerful radio jets released by accreting supermassive black holes are a significant source of magnetic energy in the Universe. By cosmic noon (redshift 2 to 3), the jet-inflated radio lobes extend beyond their host galaxies and inject…

Country-size array of radio antennas could trace ultra–high-energy particles back to supernovae and black holes...Read More

Artistic depiction of the explosive interaction between the black hole and the massive nearby star (blue). As the separation between the star and the black hole decreased, the black hole’s intense gravity pulled gas and dust off of the star into a disk. Before the star was able to swallow…
