- | Astronomers discover ‘fossil galaxy’ 3 billion light-years away [[https://tripscan.live/|трип скан]] | + | Fed-up Italian farmers set up mountain turnstiles to charge access to Instagram hot spots [[https://tripscan36.org/|трипскан вход]] |
- | A galaxy that has remained unchanged for 7 billion years — a rarity in the universe — has been observed by astronomers, offering a glimpse into cosmic history and adding to an enigmatic collection of objects called relics or “fossil galaxies.” | + | If Carlo Zanella, president of the Alto Adige Alpine Club, had his way, travel influencers would be banned from the Dolomites. |
- | These space oddities are galaxies that, after an initial phase of intense star formation, escape their expected evolutionary path. While other galaxies expand and merge with one another, the fossil galaxies remain virtually inactive. Like celestial time capsules, they provide a snapshot into the ancient universe and allow astronomers to examine the mechanism of galaxy formation. | + | He blames them for the latest Italian social media trend, which has lured hundreds of thousands of tourists to the mountain range in northern Italy, with many traipsing across private land to get that perfect shot. |
- | The newly discovered fossil galaxy — named KiDS J0842+0059 — is about 3 billion light-years from Earth, making it both the most distant and the first of its kind observed outside the local universe, the region of space closest to Earth that is approximately 1 billion light-years in radius. It was found by a team of astronomers led by the Italian National Institute for Astrophysics (INAF), using high-resolution imaging from the Large Binocular Telescope in Arizona. | + | In response to the influx, frustrated local farmers have set up turnstiles, where tourists must pay 5 euros (nearly $6) to access several “Instagrammable” spots, including the Seceda and Drei Zinnen (Three Peaks) mountain ranges. |
- | “Relic galaxies, just by chance, did not merge with any other galaxy, remaining more or less intact through time,” said Crescenzo Tortora, a researcher at INAF and first author of a study on the finding published May 31 in the journal Monthly Notices of the Royal Astronomical Society. “These objects are very rare because, as time goes on, the probability to merge with another galaxy naturally increases.” | + | |
- | Very compact, very massive | + | Photos showing lines of up to 4,000 people a day, have been popping up on social media in recent weeks. But rather than deter people from coming, the images have acted as a magnet. |
- | Astronomers believe that the most massive galaxies form in two phases, according to study coauthor Chiara Spiniello, a researcher at the University of Oxford in the UK. | + | |
- | “First, there’s an early burst of star formation, a very quick and violent activity,” she said. “We end up having something very compact and small, the progenitor of this relic.” | + | “The media’s been talking about the turnstiles, everyone’s been talking about it,” says Zanella. “And people go where everyone else goes. We’re sheep.” |
- | The second phase, she added, is a protracted process during which galaxies that are in close proximity start interacting, merging and eating each other, causing a very dramatic change in their shapes, sizes and star populations. “We define a relic as an object that missed almost completely this second phase, having formed at least 75% of its mass in the first phase,” Spiniello explained. | + | Italian law mandates free access to natural parks, such as the Alps and Dolomites, but the landowners who set up the turnstiles say they have yet to receive any official pushback from authorities. |
- | The telltale feature of fossil galaxies is that they are very old, compact and dense, much more so than our own galaxy. | + | Georg Rabanser, a former Italian national team snowboarder who owns land in a meadow on Seceda, told the Ladin-language magazine La Usc he and others started charging tourists to cross their land to make a point. |
- | “They contain (billions) of stars as massive as the sun and they are not forming any new stars — they’re doing essentially nothing, and they are the fossil records of the very ancient universe,” she said. “They formed when the universe was really, really young. And then, for some reasons that we honestly don’t understand yet, they did not interact. They didn’t merge with other systems. They evolved undisturbed, and they remained as they were.” | + | “So many people come through here every day, everyone goes through our properties and leaves trash,” he says. “Ours was a cry for help. We expected a call from the provincial authorities. But nothing. We only read statements in the newspapers. Gossip; nothing concrete. We haven’t even received warning letters. So we’re moving forward.” |
