NASA Hubble Space Telescope captures image of interstellar comet 3I/ATLAS speeding at 130,000 mph |

NASA’s Hubble Space Telescope In a groundbreaking discovery, has captured the clearest-ever image of 3I/ATLAS, a uncommon interstellar comet racing by our photo voltaic system at an unbelievable pace of 130,000 miles per hour. Marking solely the third confirmed interstellar object ever noticed, 3I/ATLAS is providing scientists a once-in-a-lifetime alternative to look at materials shaped in a completely completely different star system, probably light-years away within the Milky Way galaxy. Unlike typical photo voltaic system comets, this cosmic traveller carries with it the secrets and techniques of its alien origins, making it an astronomical treasure. Hubble’s sharp observations at the moment are serving to researchers unravel its composition, trajectory, and construction — unlocking important clues about how different planetary programs could evolve throughout the galaxy.

NASA detects interstellar comet 3I/ATLAS displaying photo voltaic system-like behaviour, Hubble Space Telescope confirms

The comet was first detected on July 1, 2025, by the ATLAS (Asteroid Terrestrial-impact Last Alert System), a NASA-funded sky survey designed to detect near-Earth objects. At the time of its discovery, 3I/ATLAS was about 420 million miles from the Sun — removed from Earth and posing no hazard. However, what makes this occasion so extraordinary is its origin: 3I/ATLAS just isn’t from our photo voltaic system.Its hyperbolic trajectory and excessive velocity affirm it’s a customer from one other star system, making it solely the third interstellar object ever noticed after ‘Oumuamua in 2017 and 2I/Borisov in 2019. Using its ultra-precise optics, the Hubble Space Telescope revealed a sunlit dust plume emerging from 3I/ATLAS and the early formation of a dust tail, similar to that seen in typical solar system comets. This glowing halo, or coma, surrounds the comet’s stable core and provides scientists clues about its composition and conduct.Though the precise nucleus — the frozen core of ice and rock — remains to be hidden beneath the coma and invisible even to Hubble, astronomers estimate its dimension to be between 1,000 ft (320 meters) and three.5 miles (5.6 kilometers) in diameter.Interestingly, the comet’s dust-loss fee — a key indicator of exercise — seems similar to that of native photo voltaic system comets situated roughly 300 million miles from the Sun. This means that whereas 3I/ATLAS comes from one other photo voltaic system, it behaves very similar to our personal cometary our bodies, pointing to doubtlessly shared bodily traits.

Mysterious origins of 3I/ATLAS

According to NASA, 3I/ATLAS doubtless originated in a special photo voltaic system, probably billions of years in the past. It could have been ejected by gravitational forces in the course of the early formation of a distant planetary system and has since drifted by interstellar area, influenced by numerous gravitational encounters with stars and nebulae.“It’s like glimpsing a rifle bullet for a thousandth of a second,” mentioned Dr. David Jewitt, lead astronomer for the Hubble observations and planetary scientist at UCLA. “You can’t trace it back precisely to where it came from.”While its actual origin stays unknown, its discovery is a component of a rising physique of proof suggesting there could also be a hidden inhabitants of interstellar objects silently passing by our photo voltaic neighborhood — most undetected till now.

“This latest interstellar tourist is one of a previously undetected population of objects bursting onto the scene,” Jewitt defined. “We’ve now crossed a threshold in detection capability, thanks to next-generation sky surveys.”In truth, at the moment’s superior telescopes and area observatories — resembling Hubble, James Webb Space Telescope (JWST), TESS, Neil Gehrels Swift Observatory, and Hawaii’s W.M. Keck Observatory — are revolutionizing our capacity to detect and research fast-moving interstellar our bodies. Each performs an important position in capturing vital information on their trajectories, chemical composition, and bodily conduct.The ongoing commentary of 3I/ATLAS by this array of devices will permit scientists to investigate its gases, mud particles, and molecular construction, giving us a deeper understanding of how comets evolve in alien star programs.

3I/ATLAS timeline: Visibility and future observations

For area lovers and astronomers alike, 3I/ATLAS will proceed to be seen by ground-based telescopes till September 2025. After this, the comet will move too near the Sun and grow to be quickly obscured by photo voltaic glare. However, it’s anticipated to re-emerge in early December 2025, providing one other thrilling probability to check this interstellar object in movement.

Why 3I/ATLAS issues: Scientific and philosophical implications

While 3I/ATLAS poses no risk to Earth, its significance can’t be overstated. Studying it might assist scientists reply some of probably the most profound questions in astrophysics:How frequent are interstellar objects in our galaxy?Do different planetary programs produce comets like our personal?Can we use these objects as pure probes into the chemistry of distant star programs?Each interstellar discovery pushes the boundary of what we all know in regards to the construction and evolution of the Milky Way, and doubtlessly, in regards to the situations that result in planetary formation and life.Also Read | NASA warns!
