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 comet broke apart. Europa Clipper used an ultraviolet spectrograph built for Jupiter’s moon Europa in what SETI described as a rapid repurpose.

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 the solar system, and scientists had a limited window to scrutinize it as it swept past Earth. NASA says the comet posed no threat and came no closer than about 270 million km (170 million miles), after being reported to

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 third confirmed interstellar object seen entering the solar system — is a fleeting opportunity to study material formed around another star.

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. Post-perihelion data are harder to capture as objects fade and move farther from Earth, leaving a narrow window to document how a fresh interstellar visitor “winds down.”  Phys Interstellar objects are rare: 3I/ATLAS is only the third confirmed body observed

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 object confirmed to have come from outside the solar system — and it is already heading back out, shrinking the window for close-up observations. It also lands as public fascination around the comet has surged, fueled by claims that unusual

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 — only the third known object confirmed to enter the solar system from interstellar space — is now moving away and steadily fading. NASA says the comet remains observable from the ground in the pre-dawn sky until spring 2026, narrowing the

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 — and it is already receding after its closest approach to Earth on Dec. 19. The comet’s unusual appearance has also become a flashpoint for claims that it might be artificial, a debate that has pushed some researchers to look

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 interstellar space. Scientists treat such visitors as time-limited samples of material formed around another star, and this one is still being followed as it recedes.

NEW YORK, January 1, 2026, 14:44 ET The most sensitive radio search yet for signs of extraterrestrial technology from interstellar comet 3I/ATLAS has found none, researchers reported this week. The result matters because 3I/ATLAS is a rare visitor — only the third confirmed object known to have arrived from beyond the solar system — and it is already receding after a close pass by Earth in December. Scientists have used the comet’s short observing window to test how quickly they can mount deep searches for “technosignatures,” a term for signals that would look engineered rather than natural, amid a surge

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.

On December 25, 2025, Comet 3I/ATLAS is already on its way out—yet it remains one of the most intensively monitored visitors of the year. After making its closest approach to Earth on Dec. 19, the rare interstellar comet continues to recede, but the science is accelerating: new analyses of its dust jets, multiple NASA and ESA spacecraft observations, and fresh radio results have sharpened the picture of what this object is (and what it isn’t). seti.org As of 06:01 UTC on Dec. 25, NASA/JPL ephemerides show 3I/ATLAS is about 1.814 AU from Earth and 2.463 AU from the Sun, with
