It’s one job over the next 6 years will be to survey the positions, shapes and distances to galaxies within 10 billion light years in over a third of the sky. The aim is to make the most detailed map of the Universe ever; a map that will help us crack some of the biggest mysteries of the cosmos. How is dark matter distributed and what it is it? Plus how the Universe's expansion rate (i.e. the Hubble constant) has changed with time and what that can tell us about dark energy… Find out more about Euclid from the @EuropeanSpaceAgency here: Read more from the Euclid Consortium: Planck collaboration (2018; figure with how Hubble constant/expansion rate has changed with time) - My previous video on what JWST will observe next year: My previous video on the evidence for dark matter - 00:00 - Introduction 00:15 - Launch and orbit 00:52 - Euclid’s one job: survey the sky 03:34 - 6 year Mission timeline 04:12 - The Euclid consortium in 16 countries 04:25 - Babbel 05:26 - Euclid instruments & wavelength 06:08 - How the map gets made 07:29 - Why the name Euclid? 08:14 - Science Goal 1: How do galaxies change over time? 09:22 - Science Goal 2: Dark Matter map & properties 11:26 - Science Goal 3: How does the expansion rate of the Universe change with time? 13:06 - Serendipitous discoveries with Euclid 14:10 - Bloopers Video filmed on a Sony ⍺7 IV --- 📚 My new book, “A Brief History of Black Holes“, out NOW in hardback, e-book and audiobook (which I narrated myself!): --- 📚 “The Year In Space“ celebrating all things space in 2022 from me and the rest of the Supermassive Podcast team: --- 👕 My new merch, including JWST designs, are available here (with worldwide shipping!): --- 🎧 Royal Astronomical Society Podcast that I co-host: --- 🔔 Don't forget to subscribe and click the little bell icon to be notified when I post a new video! --- 👩🏽💻 I'm Dr. Becky Smethurst, an astrophysicist at the University of Oxford (Christ Church). I love making videos about science with an unnatural level of enthusiasm. I like to focus on how we know things, not just what we know. And especially, the things we still don't know. If you've ever wondered about something in space and couldn't find an answer online - you can ask me! My day job is to do research into how supermassive black holes can affect the galaxies that they live in. In particular, I look at whether the energy output from the disk of material orbiting around a growing supermassive black hole can stop a galaxy from forming stars.
