A proposed mission called the Contemporaneous LEnsing Parallax and Autonomous TRansient Assay, or CLEoPATRA, seeks to work with the Nancy Grace Roman Telescope to find rogue planets not orbiting any star. Meanwhile, a possible planet has been discovered in the Whirlpool Galaxy and could be the first planet found outside the Milky Way. Plus, an interview with Dr. Margaret Meixner, Director of Science Mission Operations for the SOFIA telescope.
