Comet 3I/ATLAS News Roundup (Nov. 6, 2025): China’s Mars Orbiter Images the Interstellar Visitor, JWST Chemistry Update, and How to See It

Comet 3I/ATLAS news roundup — November 6, 2025 Today’s big development: China’s Tianwen‑1 Mars orbiter captured and released new images of the interstellar comet 3I/ATLAS (also cataloged as C/2025 N1), taken from roughly 30 million km away during the comet’s October 3 pass near Mars. China’s state outlets say the sequence shows clear cometary features and marks one of the closest probe‑based looks at the object to date. The observation doubles as a technology pathfinder for China’s upcoming Tianwen‑2 mission. State Council of China+2Xinhua News+2 What the Tianwen‑1 images add Context: ESA’s TGO produced the closest European look on Oct.

Comet 3I/ATLAS today (6 Nov 2025): China’s Mars orbiter snaps new photos as the interstellar visitor turns bluer and shows puzzling acceleration

Updated: 6 November 2025 — A rapid, reader-friendly briefing on the third interstellar object ever found, tailored for Google News & Discover. At a glance — what’s new on Nov 5–6 China’s Tianwen‑1 just gave us a rare Mars‑orbit look at 3I/ATLAS China’s space agency says the Tianwen‑1 Mars orbiter used its high‑resolution camera to observe 3I/ATLAS during the object’s close pass by Mars (early October), when the spacecraft was ~30 million km from the comet—one of the nearest probe‑based looks so far. The agency released images and a brief 30‑second sequence showing the comet’s motion, adding that the observation

Rare Interstellar Comet 3I/ATLAS – a 10-Billion-Year-Old Time Capsule – Flies Past Mars

Interstellar Visitor 3I/ATLAS Just Turned Blue and “Accelerated”—Here’s What Really Happened This Week

Key facts (updated Nov 5, 2025): The story so far: what changed in the last few days While 3I/ATLAS was hidden in the Sun’s glare in late October, it slipped into the fields of view of several solar‑monitoring cameras: STEREO‑A (SECCHI), SOHO/LASCO C3 and NOAA’s GOES‑19 CCOR‑1 coronagraph. A new analysis by Qicheng Zhang (Lowell Observatory) and Karl Battams (U.S. Naval Research Lab) reports an extra‑steep brightening as perihelion approached (scaling approximately as r^‑7.5), and color photometry showing the comet was bluer than the Sun, signaling that glowing gas (not just dust) dominated the visible output near perihelion. This is

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

Third Interstellar Comet 3I/ATLAS Stuns Scientists With Surprising Brightening and Blue Glow

Discovery and Interstellar Identity Comet 3I/ATLAS (officially Interstellar Comet 3I/ATLAS) was first spotted on July 1, 2025, by the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope in Río Hurtado, Chile newsweek.com. Right away, its orbit stood out as hyperbolic, meaning it isn’t bound to the Sun by gravity and is just passing through. This identified 3I/ATLAS as an interstellar object – a rare visitor from another star system. It is only the third such interstellar traveler ever detected, after the mysterious cigar-shaped 1I/ʻOumuamua in 2017 and the comet 2I/Borisov in 2019 space.com. The “3I” designation literally means third interstellar,

Interstellar Comet 3I/ATLAS Stuns Scientists with Surprising Bright Outburst and Ancient Origins

A Visitor From Beyond the Solar System In July 2025, astronomers discovered something extraordinary: a dim, fuzzy comet hurtling toward the inner solar system on a path not bound to the Sun. Follow-up observations confirmed this object – now named 3I/ATLAS (for the ATLAS survey that found it) – was on a hyperbolic trajectory, meaning it came from interstellar space and would soon depart forever science.nasa.gov en.wikipedia.org. The “3I” designation marks it as the third interstellar object ever observed, after the asteroid-like 1I/ʻOumuamua and comet 2I/Borisov science.nasa.gov. Unlike ʻOumuamua (which was small, oddly shaped, and showed no coma), 3I/ATLAS immediately

Interstellar Comet 3I/ATLAS Stuns Scientists – Brightening, Blue Glow & Mystery Acceleration

A Mysterious Visitor from Beyond the Solar System When astronomers spotted a faint new object moving rapidly through the outer solar system in July 2025, they quickly realized it was not an ordinary comet. Its extra-high velocity and open-ended (hyperbolic) trajectory indicated it was an interstellar interloper – an object arriving from far outside the Sun’s domain scientificamerican.com. Officially designated 3I/ATLAS (“I” for interstellar, “3” as the third of its kind, and ATLAS for the survey telescope that found it theguardian.com), this comet has since commanded the full attention of the astronomical community. “We’ve never had an object like this

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.

Ancient Interstellar Comet 3I/ATLAS Nears Sun – A 10-Billion-Year Visitor Ignites Awe and Alien Speculation

Discovery and Designation Comet 3I/ATLAS was discovered on July 1, 2025 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope at Río Hurtado, Chile esa.int. ATLAS – a NASA-funded sky survey designed to spot incoming asteroids – detected a faint magnitude ~18 object moving against the starry background ras.ac.uk. Initially catalogued as C/2025 N1 (ATLAS) under comet naming conventions, the object raised immediate excitement because its orbit did not appear bound to the Sun ts2.tech. Within days, astronomers determined the new comet was on a highly hyperbolic trajectory, not a closed ellipse like ordinary comets. In August 2025 the International

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
