The Planets with Inside-Out Weather

Vote for this video by social sharing!
Way out in the solar system, the heat of the Sun drops off dramatically, so the gas giants get just a tiny percent of the solar radiation that reaches Earth. Instead, their weather is fueled from the inside out!

    Feels good to have the first dislike

  2. NKS_Grace

    This guy’s head looks like a potato with a beard

  3. Cringe Gaming 64

    your head is upsidedown

  4. J Michael Carbonniere

    Reid, whoever set up your green screen needs more lessons! Not only did your beard look like some kind of glue on thingy (no pun intended) but it also looked like you had blond hair… where there isn’t any!

    Good info anyway, good job!

  5. ipellaers

    You mispronounced Uranus.

  6. mfaizsyahmi.

    “Uranus has no internal heat source”
    unless you had a taco at lunch

  7. Javien_Gaming

    I’m so early OMG

  8. ҳҲ̸Ҳ̸ҳ

    “Uranus has no heat source ” looks like someone hasnt done ass .

  9. God Was Bored

    My question is why you aren’t on more often than Hank. You’re just a more likeable person. Thanks for this video.

  10. Patrick Boucher

    OK. It is not heat in the conventional sense. There isn’t a band of heat between Earth snd Sun. It is Infrared radiation. This does not need a medium, such as air, to transmit. Just trying to make the world a better place.

  11. Lui.f.t

    Im early too

  12. rafaelfcf

    The beard makes his head look SOOOO large, doesn’t it???

  13. KingsleyIII

    “The gas giants get just a tiny percent of the solar radiation that reaches Earth.”
    I’m pretty sure that the gas giants get _zero_ percent of the solar radiation that _reaches_ Earth (it reached _Earth,_ not them).

  14. Osmosis Jones

    If heat is the movement of atoms not the amount of electrons how when pressure is added heat increase not decrease. . More pressure less molecular or atomic movement.

  15. Ryan Tomei-Sigurðarson

    He’s always hot lol 😋😋

  16. Nib Nab

    Oh wow I’m early

  17. Osmosis Jones

    Youanus has no internel heat source. How you explain the hot methane 😆😆😂 , or hot mud slides 💩 yours is is know for hot air.

  18. Kim Jong-un

    Some people say I’m inside out, I’m special

  19. Julio Jimenez

    I had no idea that our gas planets are contracting. As usual Reid delivered another interesting and informative episode. Also I just learned that the Earth inners never cool off because of the radioactive elements decaying in it. By the way, may Reid’s sexiness never cool off either.

  20. sean shapuron

    The helium rain theory doesn’t make sense…what gives the energy to turn liquid helium into vapor in the first place, then? As we all know perpetual motion is impossible, there must be an alternative source of energy outside of the planet itself

  21. Aragorn7884

    whoa, wtf. That green screen effect got really bad today guys.

  22. 1ctrlaltdelete1

    Jupiter is a contracting planet? I don’t understand… Is it shrinking?

  23. Zacktc 55

    Hate the beard. Looks dyed

  24. Iigmy Bigly

    So everyone knows about Dyson spheres, but they’re almost impossibly large (almost) but what if you could build a smaller one to harness the power given off by a gas giant?

  25. Valamas

    You keep pronouncing Uranus wrong. YOUR-ANUS

  26. Rechts ' is gevaarlijk

    Yes i love the bald guy! I don’t know his name and was waiting for this! Can non partions request videos?

  27. Randor

    Top 10

  28. Brent Wilbur

    Pretty sure this presenter is a digital model and not a real human.

  29. Javier Salcedo

    If Neptune and Jupiter are contracting I hope the pay is good because that weather…

  30. Rajendra Khanvilkar


  31. Gordon Chin

    So the gas giants don’t have radioactive decay heating their cores?

  32. Avaryes

    How many nuclear bombs would be needed to be buried deep into mars to make it have a similar heated core and plate tectonics like the earth?

  33. Shutter Fallmite

    Engaging comment

  34. Patrick Petersen

    so if i understand it right 50% of our core radiactiv stuff as decade so will that mean that in about 4.8b yr all of it will be gone? and our core wil be soild and we loose our magentic field

  35. linkin543210


  36. Zachary Bradley

    Why are some gas giants still contracting and others aren’t?

  37. Lowes gameing

    Honestly what is it with you people and being early this video isn’t going anywhere

  38. dementiasorrow

    Nice save pronouncing Ura-nus and not Ur-anus.

  39. Rupak CR

    You are saying that Uranus and Neptune are twins?

    Is it just me, or why tf is Reid’s scalp kinda yellow? 🤔

  43. Irwain Nornossa

    Instead 1000s and 10000000s of km, why not use Mm and Gm?

  44. Scientists Baffled

    He has wooden teeth

  45. Canis Poetam

    wait –
    _150 million kilometers_ . . .
    how many miles is that?

  46. Joseph Worrall

    Metallic hydrogen

  47. New Message

    So… we’d need to wear our raincoats UNDER our spacesuits?

  48. João Giorgini

    How many takes do you guys think 2:15 took?

  49. 3800Tech

    I wonder is Saturn has regular Helium rain or quantum rain?

  50. Jons LG

    Couldn’t you have pronounced it youranus just once? Gosh!

  51. MattverSSJ3

    GoW4 Kratos teaches us astronomy now. Okay, I’m feelin’ it!

  52. Stock Name

    I know it wouldn’t taste like anything, but I wanna taste helium rain.

  53. wolfanarchy1

    It’s so weird seeing kratos without his ash markings. Fatherhood changes you I guess.

  54. Jonathan Munn

    The question I have is what happens when all of the Earth’s radioactive materials that help keep the core moving have stopped being radioactive?

  55. Ned Laskov

    Everyone’s attempts in pronouncing Uranus as muffled and squashed as possible in order to avoid it sounding like the other thing is amusing (and a little pathetic, because you just draw more attention to it) :D

  56. Paul McMaster

    So if Uranus has no internal heating, I guess we can’t stick a thermometer inside it to find out the temperature…

  57. Rebecca Alfred

    That’s so cool!

  58. Matthew Topping

    My boy rockin’ a magnificent beard now

  59. Yu Tub

    I like the way he pronounces Uranus :)

  60. Pratik Parmar

    2:16 about the same temperature as what ?

  61. mbanana23456

    Makes me wonder if you’ll have to worry about radiation poisoning if you dig too deep.

  62. Doogle

    When SpaceX successfully hops their prototype starship, will y’all be putting out a video about it?

  63. Ricardo Thomas Manuel Her

    Look at that glorious beard! Reid, you are an inspiration. Tell me your secrets!

  64. Edward Haybell

    Alright, i’ve gotta ask. When the wind is supersonic, can sound travel through it?

  65. Adrianna Gibson

    According to my geology professors the heat generated from radioactive decay actually happens in the lithosphere not the core.

  66. Science!

    Hydrogen peroxide 1.5% mouth rinse. Works wonders on coffee stains.

  67. Alex Trainor

    You guys should put some soundproofing in the room you record in. You can the reverberation from the walls.

  68. thetommantom

    I swear it’s already snowing where I live. It just melts before it hits the ground. Evaporating, condensing blocking sun’s heat and melt raining

  69. R WM

    When you say “still contracting” does that mean we expect them to stop eventually? Or we expect to find them already contracted?

  70. Myke Prior

    This doesn’t make any sense. You’re telling me over that many eons there’s still heating and compression occuring and equilibrium hasn’t been reached? I get there’d be some “heat pressure” keeping it from collapsing, but so would equilibrium being achieved from the energy it obtains from the sun.
    It’s either there was so much heating initially it should’ve blown up the gas giant or the heating is coming from another source, like something to do with the metallic hydrogen core. It could also be that being such light gases the resistance to flow is also a lot less in the upper layers, resulting in crazy winds just at much lower densities than earth.
    Absolutely nothing to back this up, just logicing.

  71. Richie Reynaga

    Someone should make a movie called inside out.

  72. bornbill

    Love the YouTube SciShows however could you refrain from covering the beautifull graphics with your opaque banner headings!

  73. Proxima Centauri

    Impressive how quick and thorough you are while staying on point and keeping it interesting. At least for me. Nice.

  74. Burak Anıl İnce

    Where do I know this guy’s voice from

  75. 18matts

    You ever been looking at the science news and see an article that looks really interesting, but you pass on reading it immediately because sci space is probably going to talk about it. Mars wasn’t that wet? Let’s talk about that

  76. Starfals

    This brings memories from the childhood 😂🤣

  77. mike londres

    2:15 ok wait, how do you know that about me

  78. Avery the Cuban-American

    Muscle Hank has inside out weather. Even the Pixar movie Inside Out has inside out weather, it’s literally in the name

  79. J. Megatron

    Im so old that I was taught this contraction of gas giants was a source of the electromagnetic fields. #1996

  80. GlitterJuice


  81. Derek Lam

    Super interesting! I’m curious about how Saturn could still have uncondensed helium. What regenerates it, if anything? Is the underlying source of energy coming from the planet’s rotation (that’s slowed by the helium rain’s friction)?

  82. Bálint Szarka

    I feel like the youtube compression algorithm cannot handle your beard in all of its’ glory.

  83. Militant Pacifist

    How do you organize an astronomy party? You planet.

  84. Pit Worcester

    Helium falling sounds so strange…

  85. DDPWE

    The images we get now are absolutely amazing! I know previously we had artists make their interpretation of the info and were stunning.

  86. The Exoplanets Channel

    Very interesting. My team recently discovered a new Uranus-like exoplanet candidate, super-puffs are exciting! By the way for those who might not know it, a super-puff is a type of planet with a mass only a few times larger than Earth’s but a radius larger than that of Neptune.

  87. Cameron P

    My question is why Uranus doesn’t produce any heat, especially since it is so similar to Neptune?
