- On earth it rains water, on the exoplanet WASP-76b, it rains liquid iron, but no matter what planet you're on, the rain drops there have a lot more in common than you might think.

Hank: "If you think about the planets in our solar system..."
**subtly includes Pluto**
As it should be.
@@RedLeader327 🤣🤣 sorry American people, you're so funny with this little stone!
@@yuri4games34 eh, that’s an unsupported generalization. There are Americans who do not hold this opinion of Pluto, just as there are non-Americans who do.
@@JDB2552 I never said all Americans 🙂 but only Americans still believe that Pluto is more than a small pebble among thousands of others. Maybe it's because it was the only body found by an American... 😋🥰
Pluto is a dwarf planet :
Scishow: "Raindrops are not actually tear-drop shaped."
Also Scishow: "Let's make the thumbnail for our raindrop episode a picture of tear-drops."
Well, the tear-drop shape is what most people picture when they think of raindrops, so if the point ofthe thumbnail is capture peoples attention and have them understand what the topic is about at first glance.... then it did the job... ;)
@@josephinejensen3631 Also, show a background of drops falling from a solid surface, where they *do* start out tear-shaped-
"...because, you know,,...Purple Rain."
Oh, Hank, we adore you, hideous shirts and all xoxo
Now, I want to know about all the shapes of snow that could happen on other planets
would iron snow still be light and fluffy? and due to the crystalline structure refracting light... i wonder what color it would be?
@@lubbock2704 and how many sides would it have?
@@lubbock2704 We are probably very lucky to have the kind of snow flakes we do. They only look like that because of their hexagonal crystal lattice and the fact that they normally form flat structures instead of columns when they are at normal winter temps, but the possibility of other materials on other planets having both hexagonal crystal lattices and being the right temp for flat structures is probably very small. Materials like methane doesn't even form a solid unless they are enclosed in water and iron forms a cubic lattice which would probably make for a very cubic snow flake that would not be flat. However the way that the molecules seek the closest place to connect might mean they would still make spikey structures. I am not a chemist, just a guy who loves science and just did one hour of research so don't take what I say as fact
@@bobthegoat7090 Wow, I quite appreciate this long explanation out of a random youtube comment. it was kinda a joke at first but now I'm going to actually look into snow formation and making alternative snow types. I've even got an easy-ish test rig in mind to explore the exotic conditions needed for this.
You would need a magnetic field like earth, to create seasonal patterns. Otherwise it's just one repetitive season
*finds a planet that has rainstorms of gold*
Ferb, I know what we're gonna do today!
Oh. Oh no
Considering the temperatures at which gold is liquid... you do not want to be there.
Yeah unless you like being set on fire and you know leaving a very interesting corpse for someone to recover I would not advise going anywhere in that planet's atmosphere.
Let's just put it this way you thought bird strikes were bad now imagine molten iron and molten gold in your engines...
@@pierrecurie you just discovered the hell. xD
Dude rain drops are like totally metal!
Me: on some planets, yeah
You must be fun at parties
Get me talking about the second law of thermodynamics and you can literally feel the overall entropy of the universe increasing. Science, it's a party.
@@jzay1899 Good one, hats off
I mistook what channel this was at first. The thumbnail and the title led me to believe this was a hardcore music video I was clicking on. I now need Hank to shred it.
Hardcore?
Maybe emo
He totally did have a band at one point.
"But if this research... _holds water_ ..." *smirk*
Physicist pun. 😉
The Purple Rain reference took me by surprise and made me giggle 😄
In the future, there will be a correspondent from the Weather Channel standing on the surface of a planet during a molten rain of iron, screaming in agony as they report on the phenomena.
I could imagine the damage iron rain could do to people and structures...
@@centauria9122 tiny little anvils tapping through your windowpanes.

More like machine gun fire
Jim Cantore’s great, great, great, great grandchild. 😂
@@centauria9122 That's what umbrellas are for... and underground bunkers... sky cities? Actually... just don't build on those planets.
0:05 I love this image as much as Pluto loves us!
The weather forecast for a planet that has liquid metal as rain goes like: Rain - 100% Humidity - 0%
In astrophysics all elements except hydrogen and helium are considered "metals". So oxygen is a metal, dihydrogen monoxide is a metallic compound. In that sense you do live on a planet that does have liquid metal (compounds) as rain.
Metal vapour could count as "humidity"
@@DunnickFayuro"the air is thick today" brings a whole new meaning.
"if this research holds water" i see what you did there
this vid made me think that the Iron Giant's race just subsists on metallic rain
Good movie, old but good.
Imagine if it rained hunks of molten meat on Earth
@@nzuckman I'd rather not
@@SkydreamerStudios Lol
I’ve had a rough day today. I needed the smile this comment gave me.
🎼 Raindrops are falling on my head.
I mean, just the once because it was so heavy, now I’m dead
🎵Raindrops were falling on my head...
and with their weight that means I'm surely, truly, and well...dead
(Thanks for the inspiration! Lol)
Bully Metalguire:"I wanna put mercury in ur eyes"
@@annedrieck7316 that all you got?
...and hot. Those metal raindrops would be REALLY hot.
@@Mooseableg gonna cry?
In the Jasa studio it's raining glass. Must wear shoes, can't touch anything metal, and bring extra clothes when holes get melted into the ones your wearing. 👍
Majestic! A raindrop is a raindrop, even in a metal!
"A Raindrop is a Raindrop, you can't say it's only a half"
*funny mario music starts*
Reminds me of the Droplet probes from the Three body problem series.
Jajajaja I was thinking the same
It seems that not a lot of people have read or heard about the series. Which is a shame because it is one of the best sci-fi series I know.
WAIT wait wait wait. Thank you for including Pluto 💜💜💜
Oh, majestic! A raindrop is a raindrop, even when it's metal! But alas, not too fast...
Was starting to think I was the only one who saw it. Thank you.
Yay! HANK!
My favorite ever present educational entity. We should class you as SAFE, and assign some Foundation bodies to sub and keep and eye on you; as well as research exactly how you manage to show up on so many channels.
Fortunately for you, Simon Whistler is higher up our containment priorities due to his manifestation of various infographic UA-cam channels on such a frequent basis.
After seeker I'm always afraid these will end up being 10sec gifs too :-D please never change
?
Please explain
@@kendomyers I think they might be implying that Seeker is low effort maybe? They definitely aren’t what they used to be years ago
Thanks... I am pondering... super cool! 🌈❤️🚀☮️🕳🦟
Very well done. Thank you. :)
This is interesting. I work in a foundry and can confirm that falling droplets of liquid iron largely conform to these descriptions of raindrops. These droplets are generally more-or-less raindrop sized, and have correspondingly low masses to high surface areas. This means they can radiate off a lot of heat while falling through the air even short distances. They generally freeze solid while falling (if you can call an object still several hundred degrees F frozen), thus preserving their droplet shape even after being picked up off the floor later.
These droplets are not teardrop shaped but are usually fairly spherical, sometimes slightly flattened. I don’t think the flattening is due to the droplets hitting the floor while still somewhat soft because these are very small, light objects falling short distances at low speeds, and also their surfaces on the flattened areas don’t look any different from the rest of their surfaces.
The only difference I can see between raindrops and iron droplets is their range of dimensional sizes, as the iron can range from almost pinhead size to somewhat larger than a standard raindrop. Naturally they are all denser and correspondingly more massive. I think this difference in sizes is probably due to the fact that the iron is splashed rather than precipitated out of rain clouds, but even among rain there is a range of droplet sizes between light mists and heavy rains.
Start singing the song "raindrops keep falling on my head"
Why did the man use ketchup in the rain?
A: Because it was raining cats and hot dogs.
Stop 😂
Judge: 3yrs in pun prison!
Eww!
That's a "dad joke."
Hehe
Congrats on the new camera and intro and logo!
Loved the "Purple Rain" wish!
Potassium permanganate! 😂 I’ve had the very same thought seconds before I saw you say it in the video.
Potassium permanganate rain would be terrifying as it is extremely reactive. Probably wouldn't see that type of rain because of that though.
whole new aspect to the term "squall"
“Raindrops on roses, and whiskers on kittens!” 🎼
As someone who likes melting metal as a hobby, this sounds fun and dangerous at the same time. Hope your space craft has really good refractory materials.
Awesome new intro.
hank: "raindrops are not actually teardrop-shaped" video thumbnail: teardrop-shaped drops 😜
At least they got it right where it counts. A little click-bait is permissible.
@@TlalocTemporal fair nuff 😋
And a stove is a stove, no matter where you go.
Molten rain
Some stay dry and others feel the pain
Molten rain
A droplet formed will splash before the end
Molten rain
That would be like the most oxidizing atmosphere/environment ever (approx. @4:45).
Weather occurrences on other planets are always fascinating. I have no reference for anything other than a bad thunder storm though.
Can you please put your videos on Spotify as podcasts. Would love to listen to them there!
It would be very interesting in all these giant gas planets to get into their atmosphere, and as you go down the gasses start to change into liquids due to the pressure and low temperature. The interface between gas an liquid phases has to be a weird region because at that huge size it wouldn't be a very precise layer.
Dang that's metal ⚡️
Nice shirt !
Imagine the metal cloud that makes metal rain
I would write something like: "Wasp-76b is a beautiful place where titanium flowers bloom near rivers of lava and the local scientists have recently discovered sol using their telescopes, but they have since decided it has no chance of being habitable, as it is way too cold". But alas, a short search for Wasp-76b returns that its orbit is like two days.. I mean, it's tidally locked to the star. Not much hope for anything going on there.
Cool shirt!
Metal Rain...
some stay dry and other feel the pain
metal rain...
God I love Astronomy. I really hope we never quit on the dream of leaving this planet. There is so much left for us to discover!
We'll only see it from very afar and vaguely. Interstellar travel is likely impossible, no matter how advanced we get. Intergalactic travel? It would be a million times more likely for Droopy to get laid by a cheerleader.
Potassium permanganate fueled purple rain is now on my wish list.
I want that T-Shirt!!
Iron spitting lightning storms. Yes.
As above, so below.
Watching video of fronts coming across Perth, Australia in SciShow Space... odd!
Watch out for the music joke, it's easy to miss!!
You mean to tell me there is a wasp planet?
Yeah I’m not going there anytime soon.
A raindrop is a raindrop, you can't say it's only metal
Scishow: Raindrop is raindrop!
All planets on our solar system has things in common after all.
Rain drop, drop top
“The rain in Spain stays mainly in the plain “
I'm busy right now when I watch this scishow 🤓
Your prince reference made doves cry
Titan organism, with exclusively frozen water, would view us as magma people lol.
Ha! Purple rain
Please talk about the latent heat of vaporization and how water latent heat of vaporization is different from other minerals.
I doubt I'd find any other planets rain peaceful
moisture is the essence of wetness
While sad, that " please help" ad was not appropriate for a Scishow Space ad.
And a Hunter is a Hunter, even in a dream.
PRAISE THE SUN
Thats cool but if its cool to ask can we get a video on plant life on kepler 38b.
Or I think that's the stars but still its a double stare system with a Naptime size planet they believe has life on it.
So it it ok if we can see how life or plants can evolve.
Ps loved this video i known about glass rain a methane rain and rock but not iron thats cool
if it can rain iron, what is the iron version of humidity like?
Metallic.
Irony
i don't think i want to ever experience that
Well...it isn't a dry heat...ill tell you that!
Metalicity?
(I wanted to instead joke *death*)
Purple oxidizing rain
:)
metal \m/
Now all I want is an exoplanet named Africa…
If Hank gets his reference, so will I!
😂🤣😂🤣😂
🤭🤭🤭
We toto-ly get it 🙃
Raindrop, droptop.
Raindrops are round, you should know this.
Hank says it rains methane on Saturn, and I hear 'it rains farts' and loose it!
Smell something?
That is unless the potassium permanganate was heated and then put onto sintered funnel on top of a conical flask, and had a concentrated alkali added to it,
Because then it would be green rain
(at least I think)
You're just going to gloss over the whole "molten metal rain" that is mentioned in the video title? How is raining iron even possible? On that planet, is the atmosphere so dense, and the temperature so high, that iron not only turns liquid, but actually evaporates to form clouds? CAN metal even evaporate? I have sooooooooo many questions, and I feel like the title totally click-baited me.
The description does mention WASP-76B where it rains iron. Here's a more in-depth popular science piece: earthsky.org/space/wasp-76b-exoplanet-iron-rain-espresso/
@@johnmcgimpsey1825 Hank mentions it as a footnote at best. I mean, I'll watch and enjoy the video no matter what, but the title and thumbnail had me expecting something different.
In metallurgy, metal vapor is a major health hazard, so yes. All metals can evaporate at extreme temperatures. And if it can evaporate, it can condense- meaning clouds and rain.
The Codex Astartes names this phenomenon STEEL RAIN!
Imagine being hot on the head with a droplet of molten heavy iron. I wonder how that feels like
Iron melts at about 1500 degrees Celsius. So it would easily kill people.
Still nothing like the lead snow of Venus.
Dude. That's metal.
So no matter where you go in the universe, your vacation will be ruined by rain.
It is the bismuth and lead sulphide snow on Venus you have to watch for, doesn't strike me as being a good place for a ski trip!
they included Pluto as a planet 0:04 😱
Yo actual purple rain would be dope af 😂
Rain drop, drop top, cooking up dope in a crock pot
Shout out to Purple Rain
..Rains liquid iron....so that planet has gaseous iron clouds?!
Would it be possible to make a transparent window you could watch iron rain through without dying?
Did we remember to send the sound of rain on voyager?
Did the editors of this video intentionally wait to reveal Hank and his Hawaiian shirt until he was saying, "and that's not where the surprises end, either"? Because that shirt was definitely a surprise to me.
Can you imagine if life developed on a planet with liquid iron and how crazy strong it would be? It might make xenomorphs look like pet hamsters.
Or a bunch of jittery amoeboids.
Go Go Sci Show
Hope scientists find a planet where it rains chocolate someday
I wonder if there's also flash-floods on these planets where it rains different materials to water.
A flash-flood of liquid iron sounds pretty terrifying.
Iron rain? Better take an umbrella.
"...if this research holds water..." I see what you did there.
Needed more information about the Metal Rain.
