Kurzgesagt – In a Nutshell
A few days ago I shared an excellent introduction to the Solar System video that came from this channel. There's also a great white/red/brown/black dwarf video from this channel I showed to my astronomy class a few weeks back.
The great thing about this channel is that it takes complex science ideas and explains them in a very clear way to a general audience in just a few minutes. The animations are great and the creators of the videos do a wonderful job keeping the attention of the audience. A new video comes out every 3-4 weeks. I look forward to their future videos!
If you're a fan of science YouTube channels, then this channel is for you!
