Interstellar Comet 3I/ATLAS on 18 November 2025: New Multi‑Tailed Image, NASA’s Big Reveal and a Planetary‑Defense Rehearsal

Updated 18 November 2025 Interstellar comet 3I/ATLAS is having a huge day in the headlines. As of today, 18 November 2025, astronomers have unveiled a spectacular new multi‑tailed image, NASA has confirmed details of a live global broadcast tomorrow to share the sharpest spacecraft images yet, and new research is sharpening its role as a test case for defending Earth from future cosmic intruders. At the same time, fresh comments from Harvard astronomer Avi Loeb are reigniting online speculation that 3I/ATLAS might be something more than a comet – speculation that most planetary scientists still firmly reject. www.ndtv.com+2Sky at Night Magazine+2 Key 3I/ATLAS updates for 18 November 2025 What

Interstellar Comet 3I/ATLAS: ESA Sharpens Its Path as December Flyby Fuels Livestreams and Debunks Doomsday Rumors

Interstellar comet 3I/ATLAS (C/2025 N1 ATLAS) – a frozen wanderer from another star system – is back in the news today as space agencies and observatories around the world fine‑tune its trajectory, release new images and prepare global livestreams ahead of its safe flyby of Earth in December 2025. At the same time, scientists are working hard to knock down viral claims that the comet is either an alien spacecraft or on a collision course with our planet. Spoiler: it’s neither. Here’s what you need to know today. What is 3I/ATLAS – and why is it such a big deal?

Interstellar Comet 3I/ATLAS Today: Tail, Radio Signal & Viewing Guide

15 November 2025 – Interstellar comet 3I/ATLAS has survived its close swing past the Sun, grown a spectacular ion tail, emitted its first detected radio signal, and had its orbit nailed down with help from a spacecraft at Mars. At the same time, the object is fueling another round of online “alien probe” speculation – which new data strongly undercuts. Here’s a deep, news-style roundup of everything we know about 3I/ATLAS as of today and what skywatchers can actually do with it tonight.

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

3I/ATLAS Today (Nov. 13, 2025): Interstellar comet’s tail keeps growing, ‘radio signal’ confirmed natural, and a different ATLAS comet fragments

Published Thursday, November 13, 2025 Fresh observations today keep 3I/ATLAS—the third confirmed interstellar object—firmly in the “strange but natural comet” camp. Meanwhile, a different ATLAS‑discovered comet in our solar system, C/2025 K1 (ATLAS), is visibly fragmenting. Here’s what changed today, what didn’t, and how to tell these two “ATLAS comets” apart.

MeerKAT Detects Radio Signal From Interstellar Comet 3I/ATLAS — OH Lines Confirm Natural Origin (Nov. 13, 2025)

Dateline: Nov. 13, 2025 South Africa’s MeerKAT radio array has picked up the first confirmed radio signal from the interstellar comet 3I/ATLAS, a detection that strongly supports the object’s natural, cometary identity and undercuts recent “alien probe” speculation. The signal—two narrow features at 1665 and 1667 MHz—matches classic hydroxyl (OH) absorption produced when sunlight breaks apart water vapor outgassed from a warming comet. The Astronomer’s Telegram What astronomers actually detected The team reported OH absorption in both the 1665 MHz and 1667 MHz lines while observing 3I/ATLAS on Oct. 24, 2025, when the comet sat just 3.76° from the Sun

Published: 12 November 2025 The interstellar comet 3I/ATLAS is putting on fresh science today. New images show its ion tail lengthening and sharpening as the object climbs back into our predawn sky after its late‑October swing around the Sun. Meanwhile, astronomers have confirmed the first radio detection from this visitor—evidence of ordinary comet chemistry rather than extraterrestrial tech.

Astrophysicist Gianluca Masi reports that 3I/ATLAS’s ion tail has lengthened to at least 0.7°, with an anti‑tail also apparent in stacked exposures taken this morning (Nov. 11) from Italy. The session was conducted at low altitude above the eastern horizon under a bright Moon, underscoring just how active and structured the comet has become post‑perihelion.

Updated: November 10, 2025 — No threat to Earth; closest approach remains mid‑December. Key points at a glance What’s new today (Nov. 10) Radio proof of “cometness.” After weeks of speculation, astronomers have the clearest radio evidence yet that 3I/ATLAS behaves like a normal comet: MeerKAT detected hydroxyl (OH) absorption at 1665 and 1667 MHz during a deep observation on Oct. 24 while the object was near the Sun in the sky. OH is produced when water from a comet’s coma is broken apart by sunlight, and these specific radio lines are a textbook marker of that process. The team also notes earlier

Updated: November 9, 2025 What’s new today Today’s snapshot: why the comet’s look is confusing Some Nov. 5–9 images show a compact coma with little obvious dust tail, which has fueled social-media claims that 3I/ATLAS is behaving “unlike a comet.” But experts caution that viewing geometry matters: a tail can be foreshortened or lost in glare, and gas emissions can dominate the appearance around perihelion. Two days ago Space.com quoted Lowell Observatory’s Qicheng Zhang: there’s no solid evidence the coma “changed color”; instead, the gas coma is simply contributing more to the comet’s brightness. Meanwhile, a fresh deep stack highlighted
