A small rock found in the African desert has just handed scientists an extraordinary window into one of the most violent and consequential periods in the history of the Solar System. Inside this lunar meteorite, a chunk of the Moon knocked to Earth by an ancient collision, researchers have found evidence of a massive impact event 3.5 billion years ago, one that matches the timing of known impacts on Earth and in the asteroid belt. Three worlds but one shared bombardment and a story that may have everything to do with the origins of life.

The SETI Institute Releases Technosignature Report on 3I/ATLAS
Scientists at the SETI Institute searched for technological signals from 3I/ATLAS, the third interstellar object observed in our Solar System. Using the Allen Telescope Array (ATA) at the Hat Creek Radio Observatory in Northern California, the team scanned a wide range of radio frequencies for signs of extraterrestrial technology and found none, as expected based on other astronomical observations showing that the object exhibits natural comet-like composition and behavior.
“Eventually, our own Voyager spacecraft will be extraterrestrial artifacts in other stellar systems,” said Dr. Sofia Sheikh, lead author on the paper. “Given that, it is important that we understand the natural distribution of interstellar objects so that we will be able to identify any anomalies that could one day be signs of an artificial interstellar object.”
The team observed 3I/ATLAS for more than seven hours with the ATA, covering 1 to 9 gigahertz. This broad range allows scientists to search for narrowband radio signals, which are not produced by in nature and would be evidence of technology.

SETI Panel Revises Recommendations for Dealing With 'Disclosure Day'
An international committee of experts says it has updated its rules for evaluating and revealing the detection of extraterrestrial intelligence.
The revisions to the decades-old Declaration of Principles, created and maintained by the International Academy of Astronautics' SETI Committee, come just days before the release of "Disclosure Day," a movie about alien visitation directed by Steven Spielberg.

Interstellar comet 3I/ATLAS is not an alien spacecraft: SETI hunt for 'technosignatures' comes up empty
Scientists failed to find radio signals emanating from the interstellar comet 3I/ATLAS, further bolstering its status as a natural object, not one made by aliens.
