(CNN) Scientists at the University of California Berkeley's SETI@home project say they'll stop sending new work to the network of volunteers, who've been using their computers to search for aliens since 1999.

The project is going into hibernation on March 31, according to a post on its website , which said scientists have reached a point of diminishing returns.

"Basically, we've analyzed all the data we need for now," according to the post.

The scientists will now focus on studying the results they've brought in and writing a scientific journal paper on the findings.
