The great YouTube channel "PBS Space Time" did a video on Gaia and how it is changing astronomy: https://www.youtube.com/watch?v=Jdy09y0A4t0. I highly recommend the channel. I really appreciate that they don't pull any punches, you'll often see math formulas on screen! Most astronomy education material (think classic Discovery channel) tends to be extremely watered down...

Agreed, I just watched this earlier today. Space Time is the only series on YouTube where I subscribe to their patreon and continue to renew. It's my favorite series on the whole site, probably.
