It's estimated to be about the size of Jupiter, and it's orbiting the dead star at an incredibly close distance. The discovery could help us gain insight into the evolution of distant star systems, as well as our own. Planets this close to a white dwarf usually have no chance of survival, as they get sucked in by the white dwarf's immense gravitational pull. The team's finding came after they detected a gas ring around a white dwarf called G29-38, some 1,200 light years away. Within this disk, a massive planet, mostly composed of water and hydrogen sulfide, orbits the white dwarf every ten days. "This discovery is major progress, because over the past two decades, we had growing evidence that planetary systems survive into the white-dwarf stage," lead author Boris Gaensicke, from the University of Warwick in England, said in [a statement](). "Such a system has never been seen before, and it was immediately clear to me that this was a unique star," Gaensicke added. ## Eviscerated Star The exoplanet won't be around for long, though. "This star has a planet that we can't see directly, but because the star is so hot it is evaporating the planet, and we detect the atmosphere it is losing," Gaensicke said. "The orbit of the planet is most probably the result of gravitational interactions, indicating the presence of additional planets in the system," the team wrote in the abstract of [their paper](), published this week in the journal *Nature*. Their theory goes that other planets might have pushed the planet towards its eviscerated star. "This confirms what we have been thinking for the past 25 years — white dwarfs have proper planetary systems around them," lead researcher Gaensicke told *New Scientist*. **READ MORE:** [We’ve discovered a planet orbiting an exploded star for the first time]() \[*New Scientist*\] **More on white dwarfs:** *[Two Dead Stars Are Orbiting Each Other’s Corpses Incredibly Fast]()* ## 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]()
