Dr. Becky | Why it never gets dark in Norway in summer | The definition of twilight @DrBecky | Uploaded 2 years ago | Updated 3 days ago
There's no OFFICIAL "night time" in Norway in summer - it's always twilight or even a "midnight Sun". And it's all to do with how the Moon formed...

01:08 - The three types of Twilight
02:49 - Midnight Sun in the Arctic Circle
03:31 - How did the Earth's axis get its tilt?

👩🏽💻 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.
