In seven intense days spent at the radio telescope Chief scientist Dan Werthimer and his colleagues completely overhauled the way SETI data is gathered at Arecibo, and ensured that SETI@home will henceforth enjoy the benefits of gathering data with the most advanced equipment anywhere in the world.
Planetary Society members truly have helped pioneer new techniques in the conduct of science. Our initial investment has returned amazing results that will continue to deliver benefits over years to come.

On March 15, 2004, Michael Brown of Caltech, Chad Trujillo of the Gemini Observatory, and David Rabinowitz of Yale announced the discovery of Sedna – the furthest object ever detected in the Solar System.

The observatory’s communiqué emphasized that the discovery was no coincidence, but the vindication of Lowell’s predictions made years before.

Accordingly, they were named “planets,” meaning “wanderers” in Greek.
