UMBC Telescope contributes to world-wide comet observation
Before Comet ISON was destroyed by its close approach to the Sun in November 2013, astronomers at UMBC contributed to a world-wide campaign to study the coma morphology of this comet. Using hundreds of images from around the globe, the velocity of micron-sized dust grains in the coma was found to be ~ 10 m/s, with lifetimes of a few weeks in distinct jets, before merging with the dust tail.
A few days after the image on the right was taken with the UMBC telescope, the comet was destroyed spectacularly during its close approach to the Sun.
