Dale Andersen’s Astrobiology Antarctic Status Report: 14 December 2024: Departing Antarctica

by Keith CowingDecember 14, 2024January 11, 2026

Keith’s note: Astrobiologist Dale Andersen is back in Antarctica at Lake Untersee in October-December 2024 for another field season of research (preview). Dale’s work is coordinated through the SETI Institute. We’ll be posting […]

One of pur DataGarrison climate stations, situated at the top of the peninsula just behind our camp. While the station has a vantage point over both the north and south basins of Lake Untersee, this photo captures the view looking south across the southern basin. -- Dale Andersen

Jill Tarter to Receive Inaugural Tarter Award for Innovation in the Search for Life Beyond Earth

by Keith CowingNovember 4, 2024

Renowned astronomer, Dr. Jill Tarter (@jilltarter ), SETI Institute co-founder and pioneering SETI researcher, will be honored with the inaugural Tarter Award for Innovation in the Search for Life Beyond […]

An injection-recovery test using setigen used to score an isolated signal with the DOT algorithm. The isolated linearly-drifting signal seen in the target panel was injected in a region of frequency space known to contain only noise. The signal was given a width of 2 Hz, a drift rate of 0.07 Hz s−1 , and an SNR of 42,000. turboSETI calculates SNR independently from the SNR input into setigen, but nevertheless indicates a relatively strong signal as intended. The low correlation score of 0.019 indicates that the signal detected in the target panel is distinct from the pure noise in the off panel. -- astro-ph.IM

Scientists Use Allen Telescope Array to Search for Radio Signals in the TRAPPIST-1 Star System

by Keith CowingOctober 16, 2024October 16, 2024

Scientists at the SETI Institute and partners from Penn State University used the Allen Telescope Array (ATA) to search for signs of alien technology in the TRAPPIST-1 star system. The […]

Frequency coverage (x-axis) by day (y-axis) of the TRAPPIST-1 system observations using the Allen Telescope Array at Hat Creek Radio Observatory in Fall 2022. The standard radio frequency bands are shaded in the background and labeled. These observations covered a continuous 0.9–9.3 GHz in radio frequency, over two weeks in October– November 2022. -- astro-ph.EP

A Radio Technosignature Search Of TRAPPIST-1 With The Allen Telescope Array

by Keith CowingSeptember 16, 2024September 16, 2024

Planet-planet occultations (PPOs) occur when one exoplanet occults another exoplanet in the same system as seen from the Earth’s vantage point. PPOs may provide a unique opportunity to observe radio […]
