The result is a gorgeous and colorful composite image that looks like it's straight out of the Marvel Cinematic Universe. ![]() *Image Credit: ALMA (ESO/NAOJ/NRAO)* ## APEX Predator Scientists combined data from ALMA and a separate radio telescope, the Atacama Pathfinder Experiment (APEX) — freezing in time the confrontation between the two stars that resulted in a strange outburst of gas clouds. Instead of becoming red giant stars, a late developmental stage in a star's life cycle in which it becomes incredibly hot and massive, the binary system experienced something strange. "The star system HD101584 is special in the sense that this ‘death process’ was terminated prematurely and dramatically as a nearby low-mass companion star was engulfed by the giant," Hans Olofsson of the Chalmers University of Technology, Sweden, who recently investigated the star system, said in a [European Space Agency statement](). ## Star Wars In other words, one star grew into a massive red giant and swallowed the other in a death battle. The colorful rings shown in the visualization are the smaller star shedding layers of gas as it spirals towards its much larger companion star. The new image could help astronomers understand how and why Sun-like stars die in this way — a process that remains mysterious. **READ MORE:** [Spectacular rainbow cloud in space spawned by cosmic showdown between stars]() \[Space.com\] **More on binary star systems:** *[These Two Stars Will Collide in a Spectacular Explosion]()* ## 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]()
