What is John Butler doing now?
Butler's current work focuses on improving the sensitivity of the precision velocity planet search technique to detect smaller-mass and more-distant planets, and on expanding the ongoing planet survey to all 2,000 nearby Sun-like stars out to 150 light-years. Biographical information courtesy JPL.
Where did John Butler study astronomy?
Butler served as a research scientist at San Francisco State University and a visiting research fellow at the University of California, Berkeley, from 1993 to 1997. From 1997 through 1999 he was a staff astronomer at the Anglo-Australian Observatory in Australia, where he initiated the Anglo-Australian Planet Search.
