Save 40% off the Vantage plan through my link for unlimited access this month only. - I never ever get tired of seeing images we’ve taken of other worlds - other planets orbiting distant stars in our galaxy the Milky Way. This is very difficult to do though, because the star is so bright, and the planet reflecting the starlight so dim in comparison, the contrast between them is huge. We actually have to fully block the light from the star by putting a mask over the centre of the telescope, called a chronograph. JWST has one of these chronographs too, and this month we saw the latest direct image it had taken this time of the planet Epsilon Indi Ab which was published in this research paper by Matthews and collaborators. Now this image was a big deal for a few reasons, first it was actually a discovery image of the planet, it’s one of the coldest and oldest exoplanets to ever be directly imaged, AND is the closest planet to Earth that’s more massive than Jupiter at around 12 light years away. So exciting for a number of reasons and in this video we’re going to dive into why it’s exciting and what we can learn from it.

👩🏽💻 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.
