The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS) is a groundbreaking project focused on detecting extraterrestrial intelligence (SETI) signals within the Milky Way. Led by Akshay Suresh, a doctoral candidate at Cornell University, BLIPSS utilizes an innovative Fast Folding Algorithm (FFA) software, enhancing sensitivity to periodic sequences of narrow pulses. This method aims to identify repeating patterns in signals, which may suggest extraterrestrial technology, particularly in the densely populated central region of our galaxy.
The research, published in The Astronomical Journal, involves scanning large datasets from the Galactic Center, where the chances of finding such signals are heightened due to the dense star concentration. Unlike typical pulsars that emit across broad frequencies, BLIPSS focuses on a narrower range, improving the chances of detecting deliberate, periodic transmissions that could indicate advanced civilizations.
The collaboration between Cornell, the SETI Institute, and Breakthrough Listen marks a significant advancement in SETI research. By processing over 1.5 million time series in around 30 minutes, BLIPSS represents an effective tool in the search for evidence of extraterrestrial life, reshaping methods in radio SETI investigations.
