SETI@home is a distributed computing project where volunteers contribute their CPU resources to analyze radio data from the Arecibo radio telescope in Puerto Rico and the Green Bank Telescope in West Virginia for signs of extraterrestrial intelligence. The project has announced that they will no longer be distributing new work to clients starting on March 31st, 2020. Instead, they want to focus on analyzing the back-end results in order to publish a scientific paper. Users who wish to continue to run the project may do so, but will not receive any new work until the project decides whether they wish to start sending work again.
