Caleb Asa Scharf[2] is a British-American astronomer and popular science author. He is currently the senior scientist for astrobiology at the NASA Ames Research Center in Mountain View, California.[3] He formerly served as the director of the multidisciplinary Columbia Astrobiology Center at Columbia University, New York.[4]
Also active as a science communicator, Scharf was the 2022 recipient of the Carl Sagan Medal, awarded by the American Astronomical Society for excellence in public communication of planetary science.[5]
He received a B.Sc. in Physics from Durham University and a PhD in Astronomy from the University of Cambridge.
Scharf conducted postdoctoral work in X-ray astronomy and observational cosmology at the NASA Goddard Space Flight Center and the Space Telescope Science Institute in Maryland.[6]
He has an extensive research record in observational cosmology but more recently works on topics in exoplanetary science and astrobiology.[1]
He is the author of the upper-level undergraduate textbook Extrasolar Planets and Astrobiology,[7] published in 2008 by University Science Books, CA. This book won the 2011 Chambliss Astronomical Writing Award and medal from the American Astronomical Society. He has many published professional papers in peer-reviewed journals, with 109 papers listed in the SAO/NASA Astrophysics Data System (ADS); three have been cited over 100 times each: the highest counts[when?] are 264[8] 139,[9] 116,[10] all in The Astrophysical Journal.
His blog Life, Unbounded appears at Scientific American and covers topics in astronomy, exoplanetary science, and astrobiology.
Scharf is the author of a number of popular science books. Gravity's Engines: The Other Side of Black Holes (US subtitle: How Bubble-Blowing Black Holes Rule Galaxies, Stars, and Life in the Universe) was published in December 2012.[11] It was listed as one of the New Scientist top 10 books to read in 2012 and as one of The Barnes and Noble Review Editors' Picks: Best Nonfiction of 2012.
