It was likely a type of mysterious cosmic outburst referred to as fast radio burst (FRB), which have long puzzled astronomers. But thanks to a new [ study]() about the strange magnetar, published this week in the *Astrophysical Journal Letters,* that could be starting to change. In late April, the international team spotted something entirely unprecedented: an FRB originating within the Milky Way, emanating from a magnetar called SGR 1935+2154, some 30,000 light-years away from Earth. These outbursts tend to be so bright that they're billions of times more luminous than the Sun — but only last for a split second. The discovery was made possible by the "Burst Alert System" built into the European Space Agency's INTEGRAL (International Gamma-Ray Astrophysics Laboratory) space telescope, which "automatically alerted observatories worldwide about the discovery in just seconds," as Sandro Mereghetti, astrophysicist at the National Institute for Astrophysics in Milan, Italy, and lead author, explained in [a statement](). FRB hunters at the Survey for Transient Astronomical Radio Emission 2 (STARE2) in the US were able to confirm the dazzling sight just hours later. The observation could settle the major mystery surrounding FRBs: whether they do indeed originate from magnetars. "We've never seen a burst of radio waves, resembling a Fast Radio Burst, from a magnetar before," Mereghetiti sated. "This is the first ever observational connection between magnetars and Fast Radio Bursts." "It truly is a major discovery, and helps to bring the origin of these mysterious phenomena into focus," he added. **READ MORE:** [Dead star emits never-before seen mix of radiation]() \[European Space Agency\] **More on the burst:** *[Scientists Detect Powerful Radio Burst Coming From Our Own Galaxy]()* ## 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]()
