Join us for a Hubble Hangout at 4 p.m. ET May 8. With the Hubble Space Telescope , if astronomers missed seeing something once in their data, they havent missed it forever. Thanks to the wealth of information stored in the Hubble data archive, and given enough time to come up with more clever ways of scientific analysis, they can revisit existing observations and make new discoveries not caught initially. Such is the case with four disks of planetary debris uncovered in images of young stars that astronomers retrieved from the Barbara A. Mikulski Archive for Space Telescopes (MAST). A fifth disk image, which was an unpublished borderline detection by Hubble from 2007, was also recovered. These disks are telltale evidence for newly formed planets. Please join Tony Darnell as he discusses an amazing technique developed by Dr. Rémi Soummer and his team at STScI to extract hidden planetary disks from Hubble data. The technique involves systematically removing bright light from a star, eventually revealing the disk hidden in its glare. youtube/watch?v=WWZ7JhJeLRM
