An ASTROPHYSICIST'S TOP 5 space news stories of 2024

2025 has seen a LOT of big astrophysics and astronomy news announced, and while I’ve tried to cover as much as I can on this channel, I could never keep up with the pace of work of my colleagues because over 33,000 astronomy research papers have been published in 2025 alone! Some of those made a bigger impact than others though, so as is becoming tradition on this channel, I figured since we’re nearing the end of the year, let’s count down my Top 5 biggest space news stories of 2025... 00:00 - Introduction 00:43 - NUMBER 5 02:14 - NUMBER 4 04:08 - NUMBER 3 06:22 - NUMBER 2 07:57 - NUMBER 1 Madhusudhan 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
