Speaker: 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.

Recorded live on Tuesday, September 1, 2020.

The STScI Public Lecture Series offers talks on a diverse selection of cosmic topics, typically held the first Tuesday of every month. The 2020 Public Lecture Series is implementing an online-only format. This lecture will be presented with a livestream to YouTube, and questions can be asked in the YouTube chat. As usual, the recording will also be posted on our YouTube channel. We will, as necessary, adjust from the traditional first Tuesday at 8 PM schedule to accommodate our speakers.
