Sailing across the Local Universe with ULLYSES: A Hubble Program to Observe Ultraviolet Light from Young Stars
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.

Herbig Haro 666 is a young star that is shooting out narrow collimated jets in opposite directions. The jets are a byproduct of material falling onto to the star. The material is heated and then escapes along the star’s spin axis. Blazing across space at 200,000 miles per hour, the jets provide a way for the star to slow its spin by carrying off angular momentum. The star is hidden deep within the obscuring cloud of gas and dust shown in the Hubble visible-light image. In Hubble’s infrared view, the cloud mostly disappears, revealing the stars within. The jets will extend out to a light-year before dissipating. Jets are a dramatic example of the interaction between stars and the gas and dust that surrounds them.
