Speaker: Travis Fischer (Space Telescope Science Institute)

Active galaxies are some of the most fascinating objects in the universe. They emit copious amounts of energy, often exceeding the energy output of an entire galaxy of stars. But what makes them so active?

Dr. Travis Fischer will explore the nature of active galaxies, including their energetic processes and the role they play in shaping the universe we see today. Hear about some of the latest research in the field, along with the use of telescopes and other observational tools to study these enigmatic objects. Join us on a journey to the heart of the most powerful objects in the cosmos.

Recorded live on Tuesday, March 7, 2023


The STScI Public Lecture Series offers talks on a diverse selection of cosmic topics, typically held the first Tuesday of every month. The 2023 Public Lecture Series is continuing 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.
