SETI@Home at Arecibo

Di Luigi Morelli

Stavolta sembra che ci siamo: dopo quattro anni di accumulo di dati, il progetto SETI@Home e' pronto per procedere alla riosservazione dei 150 migliori candidati.

Dopo una lunga selezione di impulsi, gaussiane, triplette, ETI e controlli incrociati. il progetto avra' l'uso dell'intero radiotelescopio di Arecibo per otto ore e tre giorni consecutivi, esclusivamente per "tornare sul luogo del delitto" ed eseguire un nuovo controllo delle sorgenti radio piu' promettenti.

For nearly four years, the SETI@home receiver atop the giant Arecibo radio telescope has been surveying the skies in search of an alien signal. For nearly four years, millions around the world have been processing the raw data from Arecibo on their personal computers in search of unique patterns that might represent an intelligent transmission. No less than 5 billion(!) different candidate signals have now accumulated at SETI@home headquarters in Berkeley. Each of these just might be that one true signal from an alien civilization.

And now, for the first time, SETI@home scientists will put this mountain of data to a test.

For eight hours each day, on March 18th through the 20th, SETI@home scientists will have the full use of the Arecibo radio telescope, the largest in the world. They will use it to target between 100 and 200 locations in the sky where the strongest, clearest, and most promising candidate signals have previously been detected. Only a candidate signal that has been revisited and confirmed in this manner can be considered to be a potential intelligent transmission from the stars.

Follow the SETI@home team as they journey to Arecibo to take a second look at those elusive signals from the skies. From the early preparations to the final analysis, this is your site for following SETI@home's return to the scenes of its most promising candidates!
