Rain on Other Worlds

44 comments

On OGLE-TR-56b it only rains ironically

What kind of umbrella would be required in each world?
- Earth - any water repellant fabric, probably synthetic
  Venus - I'd go with Teflon and extend it to the ground
  Titan - SCBA
  Neptune and HD 189733b - something hard and durable but lightweight. I'd go with titanium. Chainmaille extending to the ground.
  OGLE-TR-56b - tungsten, with a mobile support apparatus.
  
  Earth needs a bit more than fabric sometimes. Not only can that water fall in the solid phase, occasionally it moves really fast!
  A SCBA isn't an umbrella. The rain is just more conductive atmosphere though, so you'd need a higher setting on your personal heater.
  Neptune probably doesn't have ground, and HD 189733b definitely doesn't. Anything capable of surviving the pressure at that depth would probably be fine, although we don't know how large the diamonds would be or how sharp the flakes that form are. Diamond Shuriken Rain sounds like an awesome song though.
  OGLE-TR-56b also probably doesn't have any ground, but depending on how high you're flying you might want something non-stick. Tons of iron welding itself to you is possibly the worst case of wing-icing you can find in nature.

okay. so. like... given that "diamond" is a particularly defined cyrstalline form of carbon. Does neptune rain solid diamond? wouldn't that be more like.... 'hail'?
also. it's always fun to me reading some older scifi where they colonize venus because it looked like... how we look at mars today.
- I read old scifi where Venus was full of rainforests. That's not how we see Mars today
  
  There was a young adult sci fi series by Asimov called 'Lucky Starr' and I remember Venus was Oceanic in that one. Old old series.

- Nah there aren't any slaves to exploit on other planets, so they aren't interested
  
  Yeah, and we've never transported slaves to a new world on ships before.
- Me: ‘lmao other planets Get fucking wrecked, suck on deez ive got fucking water’
  Debeers: wistful

Not one of these is "men."
I'm starting to think that song was a lie!
:P
- It rains men on Uranus.
  
  Got eem!

Funny thing is that there'd be enough diamonds that even the market crash of hauling a shitload of them back to earth wouldn't stop you from making absolute bank off selling them.
Probably mostly to scientists and specialist mining companies but hey money's money.
- Diamonds aren't actually rare, and the people who control the market would have you executed.
- Jevon's principle would save your ass

I want to feel the nice warmth of molten iron on my shoulders. Give me that amazing summer glow only OGLE-TR-56b can provide
- Why wait? There are foundry positions open everywhere.

I wonder what diamonds created in a gas giant atmosphere look like. Neptune has crazy high wind speeds.

Why are scientists absolutely terrible at naming planets?
- They ran out of Greek gods.
  
  naw. they just stopped naming the children after the first couple rounds of olympians.
  why name them when there's a few hundred a month? breed like rabbits, Olympians. probably out of boredom.
  
  Then use words, or some blob of syllables of some kind of description.
- It's like in No Man's Sky where you start out giving thoughtful names to every planet you come across, but after about twenty systems you're running into similar world types and color schemes that evoke the same names you've already used, so you just stop giving a shit and stick with the names the planets are generated with.
  
  I guess that's a good point.
- There are approximately two metric shit tons of planets. I assume scientists have better things to do with their time than to sit around and think of names to give to every single one of those.
  
  I just assumed all the ones we would actually hear about would get named more regularly. But I guess if they're talking about a specific one, this would happen. I never really thought about how many must really be out there, but now it seems obvious.
- They do have rules, they're not completely pulling these names out of their arses

How do you define rain on a gas giant?
- The same way you define rain in a cloud, when it condenses and falls. Of course diamonds would be hail, not rain.
  
  "condensed carbon". It might work..
