Brown dwarfs are small and dim stars that glow feebly in the infrared and are very difficult to detect. A recently launched citizen science project, Backyard Worlds Cool Neighbors, enlists the public to help identify brown dwarfs from data taken by the NASA Wide Field Infrared Explorer (WISE) satellite. In this podcast, Aaron Meisner talks about this new project and how the public can help find these elusive brown dwarfs.    Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona. Aaron Meisner is an astronomer at NSF’s NOIRLab in Tucson affiliated with Kitt Peak National Observatory. Aaron works on Kitt Peak’s Dark Energy Spectroscopic Instrument (DESI) project, a newly installed spectrograph at the Mayall 4-meter telescope. He specializes in building astronomical maps using large data sets at visible and infrared wavelengths.  These maps are used to search for moving celestial objects, like new neighbors to the Sun and hypothesized planets in the far reaches of our own solar system. To this end, Aaron co-founded the popular Backyard Worlds: Planet 9 citizen science project and the Backyard Worlds: Cool Neighbors project.    Austin Humphreys is a Banneker Key scholar and a rising senior at the University of Maryland, College Park working towards a dual degree in astronomy and physics. Working remotely from Maryland with the Backyard Worlds: Cool Neighbors team, he is an experienced coder having experience in both physics-based and astronomy-based research projects as a part of his undergraduate education, ranging from plasma physics simulations to photometric analysis of planetary nebulae. Prior to his college education, he had the opportunity to be an observational assistant at the Maryland Science Center's Crosby Ramsey Memorial Observatory for three years where he would operate and maintain an 8-inch refractor telescope for the public.   Links:  NOIRLab Stories:  https://noirlab.edu/public/blog/newly-launched-backyard-worlds/ Backyard Worlds: Cool Neighbors Launch Announcement:  https://noirlab.edu/public/announcements/ann23020/  Backyard Worlds: Cool Neighbors:  https://www.zooniverse.org/projects/coolneighbors/backyard-worlds-cool-neighbors Backyard Worlds: Planet 9:  https://www.zooniverse.org/projects/marckuchner/backyard-worlds-planet-9   NOIRLab social media channels can be found at: https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
