A trio of new planets

With the discovery last month of three more planets orbiting nearby stars, the number of proposed extrasolar planets now totals more than 50. The three objects were found with a high-precision spectrograph that analyzes starlight beaming into the 4-meter Anglo-Australian Telescope near Coonabarabran, Australia. Researchers have used the telescope since 1998 to search for planets among 200 nearby stars in the southern sky.
