Like a lighthouse, the beacon is sending out radiation three times an hour at such an intensity that it's one of the brightest points in the sky — and, researchers say, it could turn out to be an entirely new class of celestial object. A team, led by astrophysicist Natasha Hurley-Walker from the International Centre for Radio Astronomy Research, had a closer look at the object after it was discovered by Curtin University student Tyrone O'Doherty, who used the Murchison Widefield Array (MWA) telescope in outback Western Australia. "This object was appearing and disappearing over a few hours during our observations," Hurley-Walker said in [a statement](). "That was completely unexpected. It was kind of spooky for an astronomer because there's nothing known in the sky that does that." Even more intriguing is its distance from us. "And it's really quite close to us," she added, "about 4,000 lightyears away. It's in our galactic backyard." And no, before you get excited, "it's definitely not aliens," the astrophysicist [told *The Guardian*](). That's because it is releasing an astronomical amount of radiation across a huge breadth of the frequency spectrum, requiring huge amounts of energy to produce, the team found. We've spotted these kinds of objects, dubbed "transients," before — but this one is of particular interest thanks to its extremely fast flicking on and off. Usually transients appear over a few days and then disappear for months at a time — "slow transients." Or they turn on and off within just milliseconds. This object's unusual brightness led the researchers to believe they were looking at an object with an extremely strong magnetic field. In a [new study]() published in the reputable journal *Nature* this week, the team suggests it could be a "ultra-long-period magnetar." "It's a type of slowly spinning neutron star that has been predicted to exist theoretically," Hurley-Walker said in the statement. Neutron stars are the dead and extremely dense remains of a star. "But nobody expected to directly detect one like this because we didn't expect them to be so bright," she went on. "Somehow it's converting magnetic energy to radio waves much more effectively than anything we've seen before." The team is now hoping to catch the object again using the MWA. "More detections will tell astronomers whether this was a rare one-off event or a vast new population we'd never noticed before," Hurley-Walker said. **READ MORE:** [Mysterious object unlike anything astronomers have seen before]() \[International Centre for Radio Astronomy Research\] **More on magnetars:** *[A Dead Star Gave Off Something Scientists Have Never Seen Before]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
