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

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

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. Key facts about 3I/ATLAS at a glance (15 November 2025) Today’s headlines: survival, speculation and a clearer

New Glenn Launches NASA’s ESCAPADE to Mars, Nails First Sea Landing (Nov. 13, 2025)

New Glenn Launches NASA’s ESCAPADE to Mars, Nails First Sea Landing (Nov. 13, 2025)

CAPE CANAVERAL, Fla. — November 13, 2025. Blue Origin’s heavy‑lift New Glenn rocket roared off Space Launch Complex 36 at 3:55 p.m. EST, sending NASA’s twin ESCAPADE spacecraft on the first leg of a long cruise to Mars—and then stuck the vehicle’s first-ever booster landing at sea. The on‑time liftoff followed a string of weather and space‑weather delays earlier in the week. AP News+3NASA Science+3The Washington Post+3 Minutes after stage separation, the 320‑foot‑class launcher’s first stage—nicknamed “Never Tell Me the Odds”—descended to a pinpoint touchdown on Blue Origin’s autonomous landing ship Jacklyn in the Atlantic.

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

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

Comet 3I/ATLAS on Nov. 12, 2025: Tail Keeps Growing, First Radio Signal Confirmed, and How to See the Interstellar Visitor

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. Here’s what’s new, why it matters, and how to spot it. Space+1 Today’s key updates What the new images show Today’s coverage features a crisp sequence from Nov. 10–11: against moonlit, low‑altitude conditions, 3I/ATLAS displays a brighter nucleus and a longer, well‑defined

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

Interstellar Comet 3I/ATLAS on Nov. 9, 2025: Tail Mystery, New Jet Images, and Where to Look This Week

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
