Astronomers have for the first time measured the speed and direction of a newborn black hole, thanks to gravitational waves produced as it bounced away from the site of its parent black holes’ merger. This first complete measurement of black hole recoil comes almost exactly a decade after the first detection of gravitational waves — tiny ripples in spacetime first …

Sep 12, 2025, 09:01 PM ET SIOUX CITY, S.D. — John Daly made it into the PGA Tour Champions record book Friday for the wrong reason. He took a 19 on the par-5 12th hole at the Sanford International. He also broke his personal record by one shot. Daly took an 18 on the par-5 sixth hole in the 1998 …

John Daly is no stranger to big numbers. On Friday at the PGA Tour Champions’ Sanford International, Daly didn’t just hit it hard but hit it a lot on Minnehaha Country Club’s par-5 12th hole. Daly needed a tour-record 19 strokes to complete the hole, as he deposited seven balls into the penalty area, either the water that bisects the …

Black holes may be invisible, but their surroundings aren’t — and for the first time, astronomers have directly measured a superheated “corona” encircling one of these cosmic giants. The supermassive black hole, RX J1131, sits about 6 billion light-years from Earth and spins at more than half the speed of light. While the monster itself remains hidden, it gorges on …

A colossal butterfly-shaped coronal hole has opened in the sun’s atmosphere and is currently spewing a fast-moving stream of solar wind toward Earth that could trigger a moderate geomagnetic storm and dazzling auroras this weekend. The high-speed solar wind from this striking feature, spanning some 310,000 miles (500,000 kilometers) across, is expected to reach Earth around Sept. 14. Space weather …

New research suggests that there is a 90% chance that within the next decade, humanity could use a space or Earth-based telescope to spot an exploding black hole. Such a detection would change our perspective of the universe by proving the existence of “primordial black holes” born 13.8 billion years ago, a second after the Big Bang. Scientists have long …

A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new class of enormous “naked” black holes, upends the textbook understanding of the young universe. “This is completely off the scale,” said Roberto Maiolino, …

Physicists at the University of Massachusetts Amherst have challenged long-held assumptions about black holes and now estimate up to a 90% chance of observing a primordial black hole explosion within the next decade. (Artist’s concept). Credit: SciTechDaily.com UMass Amherst physicists believe such an explosion could occur within the next decade, potentially “revolutionizing physics and rewriting the history of the universe.” …

Black holes can lose mass and energy over time. They release Hawking radiation. The smaller they are, the more radiation they emit, so the hotter they get. The end scenario is the black holes exploding into nothing. Could we observe such an exploding black hole? Maybe, if a bunch of conditions are met. If they are, we could see them …

But the final reverberations as the newly formed black hole settled into its new state, aka the ringdown, from that first event were significantly fainter, and scientists were unable to distinguish between the ringing from the initial collision and the ringdown. For GW250114, LIGO’s improved sensitivity meant that scientists could measure the frequency and duration of the merged black hole’s …
