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

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

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

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 Messenger or Cosmic Time Capsule? Interstellar Comet 3I/ATLAS Stuns Scientists with Secrets

Meet the Interstellar Comet 3I/ATLAS – A Visitor From Beyond When astronomers spotted a faint new comet on July 1, 2025, they quickly realized it was no ordinary comet. Its official designation, 3I/ATLAS, tells the tale: “3I” means it’s the third interstellar object ever recorded, and “ATLAS” credits the Asteroid Terrestrial-Impact Last Alert System survey telescope (in Río Hurtado, Chile) that discovered it scientificamerican.com. In the days following discovery, observatories around the world rushed to calculate its orbit – and the results were stunning. Unlike normal comets bound in elliptical orbits around the Sun, 3I/ATLAS was on a one-way hyperbolic

Harvard Scientist’s Halloween Warning: Comet 3I/ATLAS May Hide Alien Tech and Spark Market Chaos

A Mysterious Interstellar Comet Approaches the Sun An interstellar mystery object is streaking through our Solar System this week, captivating scientists and skywatchers alike. Officially designated 3I/ATLAS (C/2025 N1), this object is only the third visitor ever confirmed to come from beyond our Solar System ts2.tech. It follows in the footsteps of the cigar-shaped 1I/’Oumuamua (detected in 2017) and comet 2I/Borisov (in 2019) ts2.tech. But 3I/ATLAS is proving to be a unique cosmic guest of its own. Discovered on July 1, 2025 by the ATLAS sky survey telescope in Chile, it immediately stood out by racing in on a steep

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

Alien Comet 3I/ATLAS Is Spewing Water Like a Fire Hose — And Scientists Are Stunned

These astounding discoveries come from coordinated observations worldwide. Below we delve into the details: what we’ve learned about 3I/ATLAS, how it compares to other interstellar visitors, and why scientists are so excited. What Is 3I/ATLAS? A Rare Interstellar Comet 3I/ATLAS (sometimes simply called “ATLAS”) is an interstellar comet – a chunk of ice and rock that formed around a distant star and is now speeding through our Solar System on a one-way trip. It was first spotted on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in Chile ts2.tech. Follow-up analyses quickly confirmed its hyperbolic orbit

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

A Visitor from Beyond the Solar System Humanity has waited a long time to study a comet from another star – and suddenly, within a decade, we’ve had three. 3I/ATLAS (officially 3I/2025 A1) is the latest of these rare interstellar interlopers. It was first detected moving through the outer Solar System in June 2025 with an exceptionally eccentric orbit. Follow-up observations quickly confirmed what its speed and trajectory implied: this object was not bound to the Sun’s gravity ts2.tech. By July 2025, the Minor Planet Center designated it the third interstellar object ever found ts2.tech. Like its predecessors – the cigar-shaped 1I/‘Oumuamua and cometary 2I/Borisov –
