Alien Probe or Cosmic Relic? Interstellar Comet 3I/ATLAS Baffles Scientists (updated 27.10.2025)

Ancient Alien Visitor? Interstellar Comet 3I/ATLAS Blazes Through Our Solar System

A Visitor From Beyond the Solar System On July 1, 2025, astronomers in Chile spotted a faint, fast-moving object that immediately stood out. Follow-up measurements showed it was on a hyperbolic orbit – not bound to our Sun – confirming it came from interstellar space ts2.tech. The discovery was officially designated 3I/ATLAS, where “3I” denotes the third Interstellar object ever observed, and “ATLAS” credits the NASA-funded Asteroid Terrestrial-impact Last Alert System survey that found it ts2.tech. This find electrified scientists. “This is only the third such interstellar comet we’ve ever been able to study, and planetary scientists are super excited to

What is Comet 3I/ATLAS? An Interstellar Visitor from Beyond Image: Interstellar comet 3I/ATLAS, captured by the Gemini South Observatory in late 2025, showing a diffuse coma and tail against the stars. This “ghostly” haze of gas and dust confirms that 3I/ATLAS is an active comet venting material as it nears the Sun. space.com en.wikipedia.org Comet 3I/ATLAS is a rare celestial visitor that truly doesn’t belong in our solar system. Officially designated 3I/ATLAS (for “3rd Interstellar” object, discovered by the Asteroid Terrestrial-impact Last Alert System), it was first spotted on July 1, 2025 by an ATLAS telescope in Chile esa.int en.wikipedia.org.

Mysterious Interstellar Comet 3I/ATLAS Nears Sun – 10-Billion-Year Visitor Sparks Alien Theories and Scientific Awe

Key Facts and Highlights A Visitor From Beyond the Solar System In July 2025, astronomers spotted a faint newcomer inbound toward the Sun – one that was not gravitationally bound to our star at all. The object, now designated 3I/ATLAS, is only the third interstellar visitor ever detected in our solar system ts2.tech. (The “3I” prefix marks it as the third Interstellar object.) It was first observed on July 1, 2025 by the ATLAS sky-survey telescope in Río Hurtado, Chile, and its discovery immediately caused excitement. The reason? Its orbit was hyperbolic, meaning it’s not a periodic comet from our Oort

As the comet nears the Sun, solar radiation vaporizes ice in its nucleus, unleashing jets of gas and dust that form a growing tail livescience.com. A Visitor From Beyond the Solar System Astronomers in late July 2025 realized that a faint new comet spotted by the ATLAS survey was no ordinary object – its orbit was highly eccentric (e > 1), meaning it wasn’t bound to the Sun at all space.com. This was the tip-off that the comet, now

Interstellar Comet 3I/ATLAS Unleashes Bizarre Sunward Jet as Scientists Quash Alien Rumors Ahead of Solar Swing-By

Interstellar Mystery Lights Up the Solar System An interstellar vagabond is currently streaking through our Solar System, and it’s making waves both in the scientific community and the public imagination. Officially designated 3I/ATLAS (C/2025 N1), this object is only the third interstellar visitor ever observed – a comet from another star now paying us a brief visit ts2.tech. First detected on July 1, 2025 by the ATLAS sky-survey telescope in Chile, 3I/ATLAS immediately stood out: it was moving extremely fast on a one-way hyperbolic trajectory, meaning it is unbound to the Sun and came from far outside our Solar System ts2.tech.

Solar System’s Hidden Edge: NASA’s Bold Quest to Map the Invisible Cosmic Boundary

Solar System’s Hidden Edge: NASA’s Bold Quest to Map the Invisible Cosmic Boundary

The Solar System’s Invisible Boundary – What and Where Is It? When we gaze up at the night sky, it’s easy to imagine the solar system simply fading into the depths of space. In reality, our solar system ends at a distinct, albeit invisible, boundary. This boundary is not marked by a wall or a halo of light, but by a balance of forces: it’s where the Sun’s influence ends and interstellar space begins indiatoday.in. Scientists call this frontier the heliopause, and understanding it is key to answering the age-old question: Where does the solar system end? At the heart

Rare Interstellar Comet Racing Through Our Solar System Could Be the Oldest Ever Seen

A Mysterious Visitor from Beyond the Solar System Interstellar comet 3I/ATLAS photographed under dark skies during a lunar eclipse, revealing an emerald-green coma surrounding its nucleus space.com. This rare alien comet carries chemical clues from a distant star system. In September 2025, skywatchers in Namibia captured a stunning sight: a ghostly green comet drifting against the starry backdrop of space. This was 3I/ATLAS, an interstellar comet – a piece of another star system – paying a brief visit to our cosmic neighborhood. Only two interstellar objects had ever been seen before (the infamous ‘Oumuamua in 2017 and comet 2I/Borisov in

Interstellar Comet 3I/ATLAS: A Visitor from Beyond the Solar System

3I/ATLAS was first spotted on July 1, 2025 by the ATLAS telescope in Río Hurtado, Chile, and officially designated 3I/2025 A1 (ATLAS), the third confirmed interstellar object after 1I/‘Oumuamua (2017) and 2I/Borisov (2019). It is traveling through the inner solar system at about 60–61 kilometers per second relative to the Sun on a hyperbolic trajectory, with perihelion near the orbit of Mars in late October 2025 (about 1.4 AU). Its closest approach to Earth will be roughly 1.6–1.8 AU (240–270 million kilometers), and it will be behind the Sun from Earth’s perspective at that time, posing no threat. The Hubble

Meet “Ammonite” – Fossil World at Solar System’s Edge Challenges Planet Nine Theory

Ammonite is the informal name for the trans-Neptunian object 2023 KQ14, discovered by the FOSSIL survey with Subaru’s 8.2-meter telescope in early 2023. Follow-up observations in July 2024 with the Canada–France–Hawaii Telescope and archival data from 2005 extended its observational arc to 19 years. Ammonite is a sednoid, a distant trans-Neptunian object with a highly eccentric orbit (e ≈ 0.74) and a diameter estimated at 220–380 km. Its orbital direction is markedly different from the three previously known sednoids, breaking their apparent clustering. Backward and forward simulations show Ammonite has been on a stable solar orbit for at least 4.5
