Europa Clipper’s UV look at Comet 3I/ATLAS backs water-ice call as radio “technosignature” scan finds none

Europa Clipper’s UV look at Comet 3I/ATLAS backs water-ice call as radio “technosignature” scan finds none

WASHINGTON, January 7, 2026, 14:24 (EST) NASA’s Europa Clipper spacecraft caught interstellar comet 3I/ATLAS in ultraviolet light while the object was hidden from Earth-based and near-Earth observatories, the SETI Institute said on Tuesday. It detected hydrogen and oxygen in the comet’s coma — the cloud of gas around its nucleus — pointing to water-ice sublimation, and saw no sign the…

Alien-signal hunt finds nothing from interstellar comet 3I/ATLAS after Green Bank scan

Alien-signal hunt finds nothing from interstellar comet 3I/ATLAS after Green Bank scan

NEW YORK, Jan 5, 2026, 04:15 ET A search for possible technosignatures — potential signs of advanced technology — in the interstellar comet 3I/ATLAS found no credible radio transmissions, Breakthrough Listen researchers reported. The team said its campaign detected no candidate signals down to the 100 milliwatt level. arXiv The finding matters because 3I/ATLAS is a rare visitor from outside…

Interstellar comet 3I/ATLAS vents water after Sun swing-by as radio search finds no signals

Interstellar comet 3I/ATLAS vents water after Sun swing-by as radio search finds no signals

NEW YORK, January 4, 2026, 18:22 ET Scientists tracking interstellar comet 3I/ATLAS with a Sun-watching spacecraft have estimated how quickly it shed water after its late-October pass around the Sun, before activity eased as it moved outward. A separate radio scan also reported no sign of artificial transmissions from the object. (https://ts2.tech/en/soho-spots-water-gushing-from-interstellar-comet-3i-atlas-after-its-sun-pass/) The readings matter because 3I/ATLAS — only the…

SOHO spots water gushing from interstellar comet 3I/ATLAS after its Sun pass

NEW YORK, January 4, 2026, 17:01 ET Scientists have measured water streaming from interstellar comet 3I/ATLAS after its late-October pass around the Sun, using a solar-monitoring spacecraft to estimate how fast the object was shedding ice into space.  Phys The timing matters because most early work on 3I/ATLAS focused on its approach, when sunlight was ramping up the comet’s activity.…

Scientists Scanned Interstellar Comet 3I/ATLAS for Alien Signals — and Found Nothing

Scientists Scanned Interstellar Comet 3I/ATLAS for Alien Signals — and Found Nothing

NEW YORK, January 4, 2026, 05:41 ET Scientists hunting for signs of alien technology from interstellar comet 3I/ATLAS reported no radio signals that could be traced to the object, after aiming one of the world’s most sensitive dishes at it during its recent close pass by Earth. ScienceAlert The result matters because 3I/ATLAS is rare — only the third known…

Green Bank Telescope schedules fresh scan of interstellar Comet 3I/ATLAS as it heads out

NEW YORK, January 3, 2026, 10:19 ET The Green Bank Telescope in West Virginia scheduled a six-hour “chemical survey” of interstellar comet 3I/ATLAS early on Saturday, according to the facility’s public observing schedule. The slot ran from 01:30 to 07:00 ET and used a high-frequency receiver band commonly used to hunt for molecular fingerprints. The timing matters because 3I/ATLAS —…

Hubble spots odd triple jets on interstellar comet 3I/ATLAS as radio search finds no alien signal

Hubble spots odd triple jets on interstellar comet 3I/ATLAS as radio search finds no alien signal

NEW YORK, January 2, 2026, 13:44 ET Harvard astrophysicist Avi Loeb said newly analyzed Hubble Space Telescope images show three evenly spaced jets on interstellar comet 3I/ATLAS, adding fresh intrigue to a rare visitor now leaving the solar system. The timing matters because 3I/ATLAS is only the third known object from beyond the solar system — after 1I/ʻOumuamua and 2I/Borisov…

Interstellar comet 3I/ATLAS spills its secrets as scientists clock its water loss and radio silence

NEW YORK, January 2, 2026, 12:50 ET Astronomers have measured water streaming from interstellar comet 3I/ATLAS after it passed closest to the Sun, using ultraviolet observations that track hydrogen released as water breaks apart, a report published on Friday said. Phys The finding matters because 3I/ATLAS is only the third confirmed object known to have entered the solar system from…

Comet 3I/ATLAS Today (Dec. 26, 2025): Wobbling Jets Detected in a Rare Sun-Facing Tail as the Interstellar Visitor Departs

Comet 3I/ATLAS Today (Dec. 26, 2025): Wobbling Jets Detected in a Rare Sun-Facing Tail as the Interstellar Visitor Departs

Dec. 26, 2025 — Comet 3I/ATLAS is already on its way out of our neighborhood, but it’s still managing to surprise astronomers on the way to the cosmic exit ramp. Today’s coverage centers on a fresh scientific twist: researchers have identified wobbling jet structures inside an even rarer feature—an apparent tail that points toward the Sun, not away from it.…
