Discovery of 32 planets announced

Astronomers working a Chilean telescope announced 32 new exoplanets (planets outside our solar system). (CNN) The telescope is outfitted with an instrument called HARPS (High Accuracy Radial Velocity Planet Searcher), which detects the slight “wobble” in stars that can betray the presence of an orbiting planet. How good is HARPS? It’s detected 75 of the 400 confirmed exoplanet and 24 of the 28 super-Earths (large rocky planets… most exoplanets are believed to be gas giants like Jupiter, Saturn).
