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.…

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…

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 (OH) absorption produced when sunlight breaks apart water vapor outgassed from…

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

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…
