UMass Amherst's Daniela Calzetti Discusses Outer Space

WGBY's Connecting Point: UMass Amherst Astronomy Professor, Daniela Calzetti, discusses the specifics of outer space. A specialist in how galaxies are formed, Calzetti is known worldwide for “Calzetti’s Law,” a tool she developed in the mid-1990s that allows astronomers to estimate how much information they are missing due to dust obscuring probes of very distant galaxies. She explains what exactly is outer space, why we send telescopes to space, how she is able to use the Hubble Space Telescope to “image nearby galaxies from the ultraviolet to the red.”
