Interview: Andrew Gould
The Ohio State astronomer discusses microlensing, stellar mass, and searching for answers.
In July 2004, Ohio State University announced a group of university astronomers directly measured the mass of a star 2,000 light years away. Andrew Gould and his colleagues recorded the star's mass using an array of techniques as well as the Hubble Space Telescope. The discovery resulted from years of data-sorting, cooperation, and a gut feeling of Gould's that previous conclusions about the star just weren't right.
