Aftermath of the Biggest Explosion Ever Caught on Camera | Shoemaker-Levy 9

[@astrumspace]

Some of you (rightfully) pointed out in the comments of the Hunga Tonga-Hunga Ha'apai video that that explosion was not in fact the biggest explosion caught on camera, so here is the true winner of that title, Comet Shoemaker-Levy 9 crashing into Jupiter, captured by Galileo and Hubble.

My father had a massive telescope when I was a child, and I saw this as a little girl in July 1994 on our cul-de-sac. Needless to say, it fundamentally changed me, and put so much of our being here into perspective, even when I was (and probably still am) too young to understand. I still remember with great detail all of the black spots; they were everywhere. The whole neighborhood came out and we watched through the telescope together, taking turns. It was absolutely incredible. Thank you for posting this video; it’s taken me back.

I remember vividly being at the Nordic Optical Telescope on the night of the first impact. There was a French group there with a thermal IR camera attached to the 2.5m telescope. We were wondering if anything could be seen since the impact was just behind the "horizon" of Jupiter. You can imagine how our jaws dropped when that insanely bright spot emerged at the limb of Jupiter. One of my top moments in astronomy!

And having both longer and shorter ones works really well to cater to what kind of mood or availability people have at any time. I’m sure a lot of people like to have the opportunity to learn new things but don’t have time, so shorter videos with fun facts and stuff are awesome!

[@Rybo-Senpai]

That is true but that would require a key hole orbit any asteroid that could theoretically be redirected by Jupiter would have to pass at a specific distance at a specific time and the odds are very very low as the most common users of a key hole orbit are man made, we alter the trajectory of our space craft to get to places like Mercury, Jupiter and Saturn, Cassini, Galileo, Messenger and Bepi Columbo have all used keyhole orbits in gravity assists to reach Mercury, Jupiter and Saturn by passing by Venus and Earth to achieve the orbital velocities required to get to the destination at a chosen time meaning the points at which the gravity assist must happen is also very specific. Using KSP with Principia mod, I can tell you getting these orbital paths is tricky as hell and nigh impossible for me, but Nasa has the resources to do it. The chances are slim but your very correct, the possibility exists.

Another point there is that Earth is a much smaller target than Jupiter so the odds of such an impact occurring are far smaller. However, one thing that Shoemaker pointed out to us through his work (I remember a video produced shortly thereafter documenting some of it with Carolyn contributing her memories and experiences) is that, if you know what signs to look for, there are impact craters *all over* the earth, some of them quite large but also quite old. That was something I found equally as fascinating as the impacts on Jupiter.

I think the most amazing part of the Shoemaker-Levy 9 story is that one of its discoverer, Eugene Shoemaker, was pretty much _the_ pioneer in this field. While ideas regarding large meteor impacts existed before him, he was the reajlly the one to bring it from the fringes to the mainstream, advancing he idea that metor strikes are common in the solar system, and most craters are impact in origin, rather than volcanic. And at the end of his illustrious career, he was able to discover -- and witness -- the one event that would prove his idea in the most spectacular way possible. That really is an achievement not a lot of scientists can claim.

However, it almost certainly was NOT as large as Shoemaker Levy 9, otherwise it would have barely left any life on the surface what-so-ever. To my knowledge even the Chicxulub asteroid that wiped out the non-avian dinosaurs 66 million years ago was a fraction the size and carried a fraction the energy of Shoemaker Levy 9.

The footage of Shoemaker Levy 9's impact was superb and very educational I'm so glad out spacecrafts happened to be in favorable positions to view that historic event we were lucky for sure. I honestly do not think that a comet hitting Earth that is as large as Shoemaker Levy 9 would cause a total extinction or even a mass extinction but a moderate extinction event. It would for sure vaporize anything within a 800 or so mile area or more. Shockwaves that would collapse structures and knock over trees and kill species would be a few thousand miles in diameter. It would also usher in an Ice Age lasting perhaps a few thousand years. Humans would find a way to survive that is the ones on the other side of the Earth from the impact and hardy animals used to the cold and oceanic life would live on. Great video as usual!

Fascinating video. Given that Jupiter is a gas giant, I assume "collision" really means an extended collision. Hitting earth would involve atmosphere (briefly) and a solid surface.
