That telescope is called Roman, and it launches really soon on Sunday, 30th August 2026. Roman is the follow-up to Hubble, it's the same size and so will give us the same level of detail in images, but it’s also been designed to look at a much bigger area of sky in a single observation: its field of view is a hundred times bigger than Hubble’s! That’s why Roman is being put to work doing surveys of the sky, splitting the sky up into patches and taking an image of every patch to meticulously record what we find there. So while all the images taken by Hubble in its 36 year lifetime have only covered less than 1% of the entire sky, Roman will cover 12% of the sky in just 17 months, a feat that would’ve taken Hubble 1700 years. But it’s not just about doing things faster than Hubble, it's about the questions the data from Roman will help us answer… Papers mentioned: Pacucci et al.

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. http://drbecky.uk.com
