Sailing across the Local Universe with ULLYSES

Sailing across the Local Universe with ULLYSES: A Hubble Program to Observe Ultraviolet Light from Young Stars Dr. Will Fischer, Space Telescope Science Institute We've all heard that a picture is worth a thousand words. Astronomers go further and say that a spectrum is worth a thousand pictures. Spectra show how bright a target is over a range of colors, revealing the temperature, composition, and other properties of planets, stars, galaxies, dust, and gas. With the help of astronomy researchers around the world, the Space Telescope Science Institute is carrying out a major program called ULLYSES that is obtaining spectra of young stars in our galaxy and beyond using the Hubble Space Telescope. It focuses on ultraviolet spectroscopy, one of Hubble’s unique strengths. Join us to learn about stellar spectroscopy and our ongoing epic journey with ULLYSES.
