Watch the launch live on 1st July 2023 at 15:12 UTC on #ESAWebTV -    • Euclid: Journey to darkness  

The Euclid Space Telescope is set to launch no earlier than the 1st July 2023 on a SpaceX Falcon 9 rocket from Cape Canaveral, FL, USA. 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…

👩🏽‍💻 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.
