UT Astronomers Race To Capture Image of Exoplanet Near Star

Brendan Bowler was part of a team to help find the lowest-mass/closest-to-its-host-star distant planet ever found.

An astronomical digitialized sky survey shows stellar patches with various levels of brightness. In a pull-out nearby, a circle is labeled JWST, with a brightest section labeled AF Lep b near a host star. Comparison lines nearby indicate how the Jupiter-Sun Distance and Earth-Sun distance compare.
