UMD astronomers catch a natural comet outburst in unprecedented detail

University of Maryland astronomers have made the most complete and detailed observations to date of the formation and dissipation of a naturally occurring comet outburst. Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), the researchers gained a clear start-to-finish image sequence of an explosive emission of dust, ice and gases during the close approach to Earth of comet 46P/Wirtanen in late 2018.
