In world breakthrough, scientists see star survive encounter with a black hole  The Times of Israel Israeli-led team first to observe star survive black hole and return  Ynetnews This star survived a black hole—and came back for more  Phys.org In a Stunning First, Scientists Have Watched a Star Survive a Black Hole Encounter  The Debrief Source link

Here’s what you’ll learn when you read this story: Over the past decade, the LIGO-Virgo-KAGRA (LVK) network has detected hundreds of black hole mergers, but none quiet as large as GW231123. At 225 solar masses, the black hole resulting from the merger far exceeds previous record holder GW190521, which weighed in at 140 solar masses. This black holes involved in …

An international team led by astronomers from Tel Aviv University observed a light flash from a star being torn apart by a supermassive black hole, only to detect a nearly identical flash from the same location two years later, named AT 2022dbl. This marks the first confirmed case of a star surviving an encounter with a supermassive black hole and …

The ground may feel steady underfoot, but the planet is always in motion. While satellites and sensors have mapped the surface in fine detail, what lies beneath remains largely unknown. The crust, a shell only 35 kilometers thick, is the farthest any probe has reached. To explore the deep interior—where the mantle and core reside—scientists must depend on indirect tools …

Observant visitors to Yellowstone National Park’s Norris Geyser Basin, the home of the park’s famous Steamboat Geyser and the hottest and most dynamic geyser basin in the park, might notice something new this year: a gaping hole filled with milky blue water. The hole was discovered by Yellowstone geologists back in April during their first visit to the Norris Basin …

In April, when Yellowstone National Park geologists made their first visit this year to the Norris Geyser Basin, they encountered a new feature they hadn’t seen before. They were checking the area’s temperature logging stations, a routine maintenance job – but since their last visit, something was different. Where previously there had been a rather featureless patch of ground at …

An image based on numerical simulations of a black hole merger – credit, NASA/Ames Research CenterC. Henze A collaboration between humanity’s three gravitational wave detectors have identified a black hole merger event that created something 225-times the size of our Sun. It’s the largest such event ever detected in the history of gravitational wave astronomy, and pushed the limits of …

In a surprising discovery last April, geologists working at Yellowstone National Park’s Norris Geyser Basin uncovered a previously undocumented thermal pool. Found during routine maintenance at temperature logging stations, the pool is located in the Porcelain Basin subbasin. This new thermal pool, measuring about 13 feet wide, features clear blue water with a temperature of approximately 109 °F (43 °C). It sits …

Two of the strangest structures in the galaxy just got even stranger. Ballooning above and below the Milky Way‘s center like a massive hourglass, the mysterious Fermi bubbles loom large over our galaxy. These enormous twin orbs of superheated plasma have been gushing out of the galactic center for millions of years. Today, they span some 50,000 light-years from tip …

Using the James Webb Space Telescope (JWST), astronomers have discovered an oddball galaxy, dubbed the Infinity Galaxy, that could be host to a “direct collapse black hole.” That is, a black hole originally created directly from a vast cloud of collapsing gas and dust rather than a dying star. The Infinity Galaxy gets its name from the fact that its …
