MacNN Forums - SETI Winter 2020 update

After the recent collapse of the Arecibo telescope, SETI@home sent out a newsletter update. They're doing final analysis on the collected data, and were not collecting new data from Arecibo at the time.

This past April, after processing 20 years of Arecibo data, we put the volunteer component of SETI@home into hibernation. We're now working on the final stage of data analysis: developing algorithms and software to reject radio interference and to identify and rank potential radio signals from extraterrestrial civilizations. This system is called Nebula. It provides a Web interface that lets you browse all our latest results. We also use Nebula to analyze data from the Arecibo SERENDIP SETI program and the FAST SETI sky survey.

You may have heard the sad news that the Arecibo Telescope collapsed this month. We conducted SETI experiments at Arecibo for 35 years and many of you analyzed Arecibo data using SETI@home.

There is more. Anyone interested should click through and read the whole letter.

They're preparing some new telescope efforts, particularly using the FAST observatory in China. FAST is an Arecibo-style dish, only bigger (500 meter vs 305m Arecibo).

My impression is they had outgrown Arecibo, so the collapse didn't harm SETI.
