500th exoplanet found

The numbering ain’t really that precise, but today scientists announced the discovery of the 500th extrasolar planet.

Based on the pace of discovery, scientists expect to discover the 500th extrasolar planet by the end of October.

Two years before anyone knew there was a Earthlike planet orbiting Gliese 581 in its habitable zone, an astronomer doing work for SETI detected a single very unusual pulse of energy coming from that area in the sky.
