#2What, in this context (and most likely all), does outside our solar system actually mean?

Like 500 light years away, as opposed to 500 a.u.

It means a planet orbiting a different star than our Sun, aka an exoplanet.

#5As with black holes, in my lifetime exoplanets have gone from being conjectural-but-likely to scientifically rich observable phenomena. I love it.

#6Woah how’s that even possible? How does the fluid pick up so much kinetic energy? I’m not saying they’re wrong, I’m just fascinated.

Some more context:
Sun -> Pluto distance is average of 40a.u.
500a.u. is 0.0079 lightyears.
Nearest star to us is ~4.5 Lightyears.
This exoplanet is ~520 lightyears away.

#8Not an original thought, but I wonder if the answer - or part of it - to the Fermi paradox is that we don't know all the ways it's possible for a planet in the Goldilocks Zone to be otherwise hostile to life.
Liquid water and.. chemistry leading to an ambient pH of 2 or 12. Liquid water and.. radiation environment such that proto-RNA strands get immediately smashed to bits by high-energy rays. Liquid water and.. bombardment every couple of million years with enormous asteroid. Liquid water and.. 1800mph super-hurricanes. etc.

#9> WASP-127b, a giant gas planet located more than 500 light-years from Earth.
How do you define "sound speed" on a gas giant?

I guess a gas giant means there's super strong electro-magnetic field.
