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

NASA’s Interstellar Visitor 3I/ATLAS on Nov. 5: Fresh Post‑Sun Images, JWST Chemistry—and How to See It Next

Key points What’s new today (Nov. 5) After weeks hidden in the Sun’s glare, 3I/ATLAS is being picked up again by ground telescopes. The Virtual Telescope Project published a clean, post‑conjunction image captured this morning (UTC), marking the start of a new observing window as the comet climbs into darker, pre‑dawn skies. The team plans additional public sessions as conditions improve. The Virtual Telescope Project 2.0 At the same time, science teams are digesting a flurry of perihelion‑time findings. Analysts note the object’s distinct blue hue reported in recent imagery—its third apparent color shift since discovery—and are comparing that trend

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

July 10 2025’s ‘Buck Moon’ Will Be the Farthest‑From‑the‑Sun, Low‑Riding Full Moon of the Decade—Here’s the Exact Time, Best Viewing Tricks & Pro Photo Hacks You Need

Today’s Moon Is a Record Supermoon: See 2025’s Biggest, Brightest Full Moon (Nov 5) — What to Know, When to Look, and Why It Matters

Today’s Moon, explained At 13:19 UTC (08:19 ET) the Moon reached the exact Full Moon moment — the point when Sun, Earth and Moon line up with Earth in the middle. Timeanddate summarizes it neatly: “Full Moon is the only phase where the Moon is up all night.” Time and Date Later today, around 22:30 UTC, the Moon hits perigee (its closest point this month), tightening the geometry into what popular usage calls a supermoon. NASA’s definition: “A ‘supermoon’ occurs when a full Moon coincides with the Moon’s closest approach to Earth in its elliptical orbit, [perigee].” The result is

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

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

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

Dueling Dinosaurs Fossil Shocks Scientists: ‘Teenage T. rex’ Was a New Species All Along

Dueling Dinosaurs Fossil Shocks Scientists: ‘Teenage T. rex’ Was a New Species All Along

A Decades-Long Dinosaur Mystery For over 40 years, paleontologists have wrangled over mysterious tyrannosaur fossils that didn’t quite fit the mold of T. rex. The controversy began with a small skull found in 1942 in Montana’s Hell Creek Formation – the same Late Cretaceous deposit that yielded T. rex. In 1988, some researchers formally named that skull Nanotyrannus lancensis, meaning “dwarf tyrant,” proposing it was a new pygmy tyrannosaur species nationalgeographic.com. However, many experts argued these remains (and others like them) were simply juvenile T. rex specimens that hadn’t grown to full size nationalgeographic.com. The question — teenage T. rex

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

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

Last Chance to See Rare Green Comet Lemmon – A Once-in-a-Millennium Sky Spectacle

Last Chance to See Rare Green Comet Lemmon – A Once-in-a-Millennium Sky Spectacle

A Once-in-a-Millennium Visitor Lights Up the Sky If you haven’t been skywatching lately, now is the time – Comet C/2025 A6, nicknamed Lemmon, is putting on its best show in late October 2025. This rare comet was first spotted in January by the Mount Lemmon Survey in Arizona sfgate.com. Since then it has been steadily brightening as it races toward the inner solar system space.com. By this week, Comet Lemmon reached magnitude ~4, making it one of the brightest comets of the year and borderline visible to the unaided eye under ideal conditions skyatnightmagazine.com. For context, that’s about as bright

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

Interstellar Comet 3I/ATLAS Shoots Giant Sunward Jet — Experts Debunk Alien Probe Rumors

In recent weeks astronomers have been fascinated by the interstellar comet 3I/ATLAS as it rushes through the inner Solar System. First spotted by the ATLAS telescope (Chile) on July 1 ts2.tech, it turned out to be moving so fast on a hyperbolic path that it could only have come from outside our solar neighborhood. Follow-up orbits confirm it is on a one-way trip, never to return ts2.tech. Importantly, orbital calculations show its minimum distance from Earth is about 1.8 AU (far beyond Mars) ts2.tech, so it will not collide with us. In fact, the comet’s closest brush with any planet was

NASA Confirms Earth’s “Secret Second Moon” – Tiny Asteroid 2025 PN7 Will Orbit with Us Until 2083

NASA Confirms Earth’s “Secret Second Moon” – Tiny Asteroid 2025 PN7 Will Orbit with Us Until 2083

NASA Announces New “Quasi-Moon” Discovery On Oct 22, 2025, space agencies worldwide celebrated the announcement that Earth has a new celestial companion. A team from the University of Hawaii’s Pan-STARRS survey discovered a tiny asteroid – designated 2025 PN7 – on Aug. 2, 2025, and subsequent orbit analysis showed it has been silently trailing Earth for roughly 60 years chron.com. NASA confirmed in a press report that this 62-foot-wide rock is Earth’s newest “quasi-moon,” meaning it is not a bound satellite but a co-orbital asteroid ts2.tech hindustantimes.com. As one global space news outlet noted, astronomers “confirmed a tiny ‘quasi-moon’ –
