The structure, believed to be largely made of dust, is located in the Beta Pictoris star system, and was first directly observed by NASA's James Webb Space Telescope in infrared light. Now, thanks to new images taken by the Hubble Space Telescope, we get to the see the tail in visible light as well, revealing a bizarre tail-like protrusion sticking out of the plane of a gargantuan, disk-shaped accumulation of cosmic dust. As detailed in an [article]() published last month in *The Astrophysical Journal Letters*, a team led by researchers at the University of Arizona were intrigued to get a closer look at the structure using the Hubble. "Oddly, this feature had previously only been seen with the James Webb Space Telescope, which detects infrared light, but remained invisible at shorter wavelengths, which has puzzled the community for a while," said research lead and University of Arizona doctoral student Arin Avsar in a [statement](). "We think the Cat’s Tail has eluded our observations in visible light until now because of what it’s made of." "It consists almost entirely of we call organic refractory material, which is heavily carbon-based," he added. "These long chains of carbon atoms absorb visible light, so they’re quite black." Scientists believe the Cat's Tail is the result of large, Pluto-like planetary bodies colliding, sending huge amounts of dust scattering across huge distances. These collisions may have generated enough heat to turn carbon into vapor, before cooling the material down into fluffy and porous grains of dust. For their research, Avsar and his colleagues combined both infrared and visible-light images to calculate the protrusion's geometry in 3D. "We find that instead of extending for 1,000 astronomical units behind the star, the Cat’s Tail may extend straight sideways relative to us, and there is no third dimension to it," he explained. "It’s essentially in the same plane of the sky as the star and possibly extends a little bit behind it." The team also observed a strange warp in the dust halo shrouding Beta Pictoris, which they say could be the result of at least three known planets in the system exerting considerable gravitational influences. The findings could give us insight into what our own solar system may have looked like just after its formation. Beta Pictoris is a mere 23 million years old, compared to our own system's 4.6 *billion* years of age. Similar interactions may have even influenced the formation of our system's planets as we know them today. **More on cosmic structures:** [*Scientists Scan Gigantic Structure Hiding Behind Our 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]() ## More - [James Webb Spots Epic Collision Between Giant Asteroids]() - [The Comets of Beta Pictoris]() - [Scientists Just Took an Actual Picture of a Planet in Another Star System]() - [Astronomers Spot “Extragalactic Structure” Lurking In Obscured Zone of the Universe]() - [Harvard Scientists Detect Radio Signal Coming Directly From Planet Outside the Solar System]() - [Planet-forming “Lifeline” Lurks in a Binary Star System]() - [Astronomers Intrigued By Impossible Structure Around Dead Star]() - [Scientists Discover Weird Structure in Outer Solar System]()
