This is obviously a ginormous leap from this announcement and just a tangent sparked by it. The possibility of intelligent life developing on a world like Europa encrusted with what is effectively a miles think solid atmosphere has always been one of my favorite feasible sci-fi hypotheticals. Could you imagine how that would impact their culture? Would they even know there is anything on the other side of the ice? Th…

Europa is definitely the most exciting part of the solar system that sparks imagination. Literally 100s of miles of pitch black ocean with thermal vents, ripe for life. Getting kiddy thinking about the leviathan sized aliens roaming the deep ocean of Europa. Does anyone else feel this way?

Well technically they would just be Europeans.

No need to dig, you just melt yourself downwards. It's not exactly like digging through rocks on Earth.
Would liquid pool up as you melt the ice? I guess you'd need to pump it out. Is that even possible at that depth? The liquid might boil on the way up.

> ALL THESE WORLDS ARE YOURS - EXCEPT EUROPA.
> ATTEMPT NO LANDING THERE.
So yes. Clarke thought it was special also.
“All these worlds are yours - except Europa. Attempt no landing there.” You have been warned guys… ;)
Honestly, the only thing I wish to see before I die is a submarine mission to Europa or Ganymede. It would be even more mind blowing and an amazing achievement for humanity, and the search for extraterrestrial life. That, and the dragonfly-helicopter-thing on Titan. Have you ever seen the Sun set on a methane lake? It's time for a rewatch of Europa Report (2013).

If you elect me, I will make all these come true!

It's less clear than I'd expected. Is that image deliberately downscaled so as to not reveal the true capabilities of the telescope optics?
No, they're quite open about the capabilities of the optics (see https://webb.nasa.gov/content/forScientists/faqScientists.ht... ). It's just that Europa is very far away. Webb's mirror system has an angular resolution of about 0.1 arcseconds. Earth is currently about 630 million km from Europa (Webb is only 1.5 million km away from earth). Because the sine of theta is approximately equal to theta for values of theta…

Of course, barring collapse, the rocks won’t reform right above you as you go.

For the conspiracy theorists: this is the same reason why we can't just point Webb at the moon and get pictures of the lunar landing sites. In terms of arcseconds of the Webb's FOV, the moon landing site is much smaller than these distant galaxies (which blows my mind just how big those distant "objects" are).
