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

Interstellar comet 3I/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.

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.

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. The recovery marks a pivotal reuse milestone for New Glenn on its second orbital mission, a leap forward after January’s debut flight reached orbit but lost the booster during descent.

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

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 absorption produced when sunlight breaks apart water vapor outgassed from a warming comet. The Astronomer's Telegram

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

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

Comet 3I/ATLAS Today (Nov. 10, 2025): First Radio Signal Confirmed, Fresh Jet/Tail Images & What to Watch Next

Updated: November 10, 2025 — No threat to Earth; closest approach remains mid‑December. 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 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 non‑detections on Sept. 20 and 28, underscoring that activity ramped up near perihelion. The Astronomer's Telegram

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 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 today shows multiple jets, including a sunward anti‑tail—a geometry sometimes seen in comets when dust sheets align with our line of sight. In short: images are real, interpretations are still being tested. Space+1

Sharper Black Hole Images Could Put Einstein’s Gravity to the Test: New Study Maps What Future Telescopes Must See (7 Nov 2025)

Published: November 7, 2025 A wave of coverage on Friday highlighted a new Nature Astronomy study that sets a concrete target for the next generation of black hole images: if upcoming telescopes can reach percent‑level fidelity, they could tell Einstein’s black holes apart from a range of look‑alikes predicted by alternative theories of gravity. The paper—published November 5—uses advanced simulations to show that when the mismatch between images exceeds roughly 2–5%, future instruments should be able to rule out many non‑Einstein models.

Blue Origin to Launch NASA’s Twin ESCAPADE Mars Probes on Nov. 9: Time, Livestream, Mission Goals, and What Happens Next

Published: November 7, 2025 Blue Origin’s New Glenn is slated to lift off Nov. 9 carrying ESCAPADE—Escape and Plasma Acceleration and Dynamics Explorers—two identical NASA satellites designed to explain how Mars lost most of its atmosphere and water.

  • Air Canada (TSX:AC) slips 52%, long-term investors eye value
    July 1, 2026, 12:29 AM EDT. Air Canada (TSX:AC) stock has lost more than half its value, down 52%, but is still trading at a trailing P/E of 10.1. The airline has made cuts and boosted operational efficiency, keeping its balance sheet stable. Jet fuel prices have dropped as U.S.-Iran tensions ease, while bookings for summer travel look strong. Air Canada has added free WiFi and more Aeroplan perks to try to gain share. The sector is still volatile, and investors looking to buy on weakness need patience and regular reviews. The recent drop could give long-term investors a shot at a better entry.
