Maria Teresa and the Brown Dwarf: The astronomer who in 1997 was the first to actually see a "brown dwarf" -- a nascent star that did not have the nuclear capability to become full-fledged -- talks about what drives her to be an astronomer, and explains that the same drive is fulfilled on different levels by her collecting of precious stones on the beach and her detail-obsessed avocational creation of tapestries. The short ends in a truly striking overhead shot in which Teresa demonstrates the formation of a galaxy by arranging different kinds of spheres -- children's sports balls, oranges, etc. -- on a bright-green expanse of lawn.
