Comet Shoemaker-Levy 9 broke apart under Jupiter's tidal forces into a chain of fragments that then collided with the planet, an event astronomers predicted in advance and watched live with telescopes around the world, including Hubble. The impacts released enormous energy, and the hosts describe the event as the moment planetary defense became a real, actively discussed area of research rather than just a concern about the dinosaurs' extinction 65 million years ago.
- 01
The hosts note a more recent example, an interstellar object that telescopes also tracked, as a parallel case of watching a space object in real time.

1:29:41from with tidal forces. So, it became this chain of cometary debris that then came back and then hit Jupiter and we could watch it live and we knew exactly when it was going to happen. All of the telescopes around the planet Earth along with the Hubble was pointed at Jupiter and you could literally watch the bombing of Jupiter, you know, and I mean it it released enough energy to like destroy Earth or something. It it's it's it was massive, >> right? And thankfully it wasn't pointed at Earth, but our big bro. Yeah. The big red planet. >> And I mean the other big thing about it is like that's when that's when um everyone was like, "Oh, so this could happen."
1:30:23>> Like we should probably be worried about it. Um this isn't just something that the dinosaurs needed to be worried about 65 million years ago. This could still happen. >> And we uh talked about planetary defense. >> Yes. That I mean this is when people started taking it seriously cuz we just watched it live, >> right? And it's like, yo, >> it's a real it's a real area of research that we definitely need to pay attention to. Uh, and then we saw um what was the interstellar object where we pointed the stuff as well at the same time uh about a year or two ago. Uh 1993, a binding change mechanism of ATP synthes. >> Yes. Um this is biochemist Paul D. Ber at UCLA. >> He figured out how cells create ATP. ATP
1:31:06is the currency of energy. for our cells. It's like it's like cash. Okay, you can think of glucose as like the industrial input, right? But from that you've got to create something liquid that can then be transferred from party
