What if the life forms are made of gaseous lava? Around Earth surface temperature, I can see the arguments for most life forms being carbon based (though I've heard silicon could have similar properties.)
But at high-energy states like that, it's kind of absurd to begin theorizing about what would or wouldn't be damaging to a life form that evolved in that environment.
I hope somebody figures out a way to damage them before the Colour from Out of Space consumes us all.
So, this is pure ho-hum to me. Let me know when they've done it a couple of dozen times.
No one is claiming this is some astounding breakthrough or unheard of application of technology. They're saying "Hey, these guys sent a video camera up to 100k feet and this is the footage they got. Cool, huh?" Most of us would say we could/would do something like this if we had the time... initiative... willingness to get off our lazy butts and do it. But most of us never will. These guys actually did, and we're applauding them for it.
Money will say more in one moment than the most eloquent lover can in years.
