[@TommoCarroll]

"Tiny space potatoes" - will now be the official name for anything space-rock related. This has been a public service announcement.

[@combatking0]

So, Phobos and Deimos are described as being potato shaped, and if they had been captured, they wouldn't be baked enough. But then the gravitational stress would have mashed them.

[@TheHelghast1138]

😎😎😎

[@khartog01]

The moons were formed when the Doom Slayer punched the Icon of Sin into ground.

[@chazeverlastt9905]

I love Mars .. I even worked on the project of identifying meteor impacts on Mars like 16 yrs ago. was fun and my Fetish of Mars ~~

[@starshot5172]

"Tiny space potato" lol

[@TommoCarroll]

Absolutely beautiful description haha!

[@TheExoplanetsChannel]

*great video as always!*

[@Richard-uf9oy]

The universe is a big place, perhaps the biggest.

[@stopbeingstupid2510]

mabey not there not realy what=t about megaveirs

[@babyUFO.]

Multiverse

[@tomshraderd4915]

SPT2349-56 isn't that memorable of a moniker, but given how gifted astronomers are in nomenclature I'm sure that we'll soon have a catchy name for it, such as "Very Active Region of Space".

[@gideonjones8088]

Considering how much astronomers love acronyms, they'll refer to it as VARS. I've heard worse, I guess

[@kantoorhandook6595]

Gideon Jones well, VAROS looks better for me

[@limiv5272]

Space is so big, and so full of things, that even if astronomers tried to give each of them a real name they'll probably run out of names long before they run out of things to name

[@thehenchdude11]

I find it amazing that as much as we want to travel back in time, and cant, at least we are able to satisfy our hunger by being able to look back in time.

[@Circulatoryful]

its so great how much you love mars, hank.

[@mathieuaudet]

DOOM!

[@khartog01]

Mathieu Audet every time I think about Mars

[@DragoniteSpam]

"The idea of 'today' doesn't really work in astronomy" Hank, stop being so good at words.

[@lakalakadakabear]

I love Hanks sarcasm and enthusiasm 😍

[@otakunfranks8145]

Thank you, Scishow. Seeing these videos, and how many others enjoy and discuss them, etc. makes me feel better about the state of knowledge/science/curiosity/understanding in the current world. It is far too easy to feel like science is losing ground to ignorance, and every bit helps. Especially when presented in an interesting, entertaining, and often funny way. Keep up the great work :)

[@WolfieDawn]

Gosh I love these videos

[@Cubenga]

What a coincidence; yesterday I was reading about Mars's moons... and wanted more info about current missions etc.

[@flipping_pancake6032]

I love Mars it's so fascinating!!!!!

[@WolfieDawn]

Love the hair, Mr. Green!

[@katiekilgore6918]

“12 and a half billion years ago, there was no Mars. What a sad universe that was.”

[@SniperNinja115]

‪Interesting, thanks for sharing and keep it up, brother, much love, take care🖤🖤..‬

[@michaelalexander2753]

Mini-Apocalypse is my new favourite phrase of the day

[@davetoms1]

Damn, I love the Complexly end screen on all your channels' videos. Y'all are family, yo. #DFTBA

[@gunslinger2566]

I haven't stopped playing Surviving Mars since it came out, so yes, I do think about Mars all the time.

[@MikeandLizzy]

I was just looking at these two on my Sky Guide app.

[@sid3986]

This is a good record to try and beat!

[@mockcoder5285]

Well I think about Mars all the time

[@MonkeyspankO]

same

[@mockcoder5285]

I had a really crazy thought what if the collision of the protoplanet with mars turned off it magnetosphere and made it lose atmosphere

[@Thumbsupurbum]

Homesick?

[@Reckec]

I think about Pluto, 5 minutes before it's spirit was crushed by having it's planetary status stolen away, when it was still a proud and a noble member of the planetary pantheon.

[@jasonbrooks7282]

I think about mars candy all the time 😜

[@Raz.C]

@ 3:08 Actually, back then we called it Thrargrphhn. It means.... Well, actually, it's no longer possible to relate what that means, as all points of comparison no longer exist.

[@queengabriellelavijahnsun8434]

Hank is the best

[@issolomissolom3589]

I love you hanks

[@FlareKangarooo]

(M)ost (A)ctive (R)egion in (S)pace Stay classy Sci Show

[@craigmooring2091]

"Unless you're like me and you think about Mars all the time". Hank is mooning over Mars and Mars' moons.

[@mysteepulcine2510]

You guys gonna post an update on the comet lander? New images all over Imgur, and it'd be cool to see what new data there is if you guys know.

[@gates10611]

Scishow Space rocks!

[@kirbymarchbarcena]

Space is truly interesting...

[@Mattrix94gaming]

Gotta love Space Spuds

[@DagarCoH]

I liked the jokes in this one. Props to Brendan Cole for writing the episode.

[@thesuccessfulone]

"Using the South Pole Telescope. Shockingly, this is a telescope near the South Pole" Hilarious!

[@Locut0s]

It’s ok guys, I’m lumpy and potato shaped too. Gives Phobos and Deimos a hug.

[@dryboneskirby]

Hank I love you

[@kellyandrichweddle2425]

I am also a huge Mars fan.

[@feedusafetus]

I know all about Phobos and Deimos. One you put a scram or point on, the other gets a warp disruption field generator. Ha ha!

[@Flame-Bright-Cheer]

I love all the topics and the professionalism including the entertainment value of this channel the things that you guys explore are amazing and you go in-depth like no one else but you tend to leave out the electric universe connection especially in regards to Mars take a look at the Thunderbolt project specifically the Mars videos love the channel thank you

[@clark1066]

From my thinking, it seems like there are regions around stars similar to the habitable regions but associate with satellite forming. The closer planets can't get moons in the early solar system because the orbit is too small so most objects would either be flung out of that particular orbit or would crash into the planet. The center region which would consist of Earth and Mars would form many more planets because of the density of matter so that would mean more collisions, and with more collisions means a more likely chance to form moons this way. Then the outer region gains it satellites from being so massive and attracting objects. However, the reason why they don't form moons like the center region did is because the amount of matter in this region is so great that after a certain period of time the planet that forms will be too large for moons to form this way as it would be too large for an impact to send enough matter into a density great enough to form a large object. This makes sense to me and I would love to hear about what other people think.

[@Soupy_loopy]

"Wet Moon", Great name for a band

[@SB-lv8yz]

I love how interesting this is!

[@TommoCarroll]

That's good to hear! Anyone interested in science is A-Ok in our books!

[@starspawn507]

The South Pole Telescope is near the South Pole?! I never would have guessed!

[@joeycook6526]

I used to not like Hank Green because he popped off at the Science Asylum guy. But I've got to say, he's really grown on me. He's one of the most entertaining and informative of the science KZbin video universe. Still... Science Asylum ftw!

[@quentintubb]

this is why you cant get a snickers sponsorship, you are always thinking about MARS

[@kyleponder2269]

"...between 10 & a 100 times lighter," at 2:19 made me double-take

[@jaywatson7286]

I expect better writing in Sci Show. If NBC news reports that something is 10 times lighter or cheaper, I'm not surprised. Science shows should expect their audience to understand fraction and ratios. 10 percent the mass, or 1/10th the mass.

[@user-vh9im5rj8r]

Heck!

[@Thoran666]

Potato science for the win!

[@TommoCarroll]

Anything potato related is generally a win, but bring science and potatoes colliding together, oh mamma!

[@LudmilMetodiev]

If we can travel trough wormhole we can look at our planet with a telescope and see it in the past.. that might be kind of time travel ... mind blowing

[@Vulcano7965]

I heard a funny hypothesis once, that Phobos and Deimos were actualy spouted into orbit by a huge volcanic eruption on Mars! How rad would that be? :D

[@lsp8390]

Lumping space potatoes yay!

[@evanweaver7373]

I liked for the profile pic

[@billybobjohn8955]

Better than lumping couch potatoes.

[@kornkernel2232]

And space Mars!

[@Devilman666]

Gotta cover that demonic invasion that happened on mars guys!

[@jamesfra1311]

What about the phobos anomaly??

[@kyokoyumi]

The feeling when you glance at it as it pops up and see "A New Origin Story for Men's Moobs"

[@elvirabos4245]

I have to make a presentation about space do you guys maybe know where I can talk about?

[@TheRadioAteMyTV]

Thank you for the first 3 minutes. The last part... uh ok.

[@sneeringimperialist6667]

They aren't lumpy! They are gravitationally challeged!

[@radix4801]

2:17 "A 100" lol

[@SouravSengupta93]

One day maybe same channel but someone else will say we have a most active region but only that time it will be about other supersmart civilizations.

[@rigrentals5297]

Scishow space for the win.

[@QuasistellarNymphomaniac]

I never forgot about our martian moons either :) Anyway, I'm starting to get the feeling that whenever something spins or orbits in an unforeseeable way in our solar system, every time the answer seems to be a proto planet collision. If I were an astronomer, I would have really smart things to say but as an amateur scientist, (at least for now) I'm going to throw it out there. Any other smart ideas to how planets form and evolve? Otherwise we will have to "donate" a lot of nobel prizes to our metaphorical children.

[@CarFreeSegnitz]

Neptune's moon Triton is suspected to be a captured Kuiper Belt object given that it's going around Neptune in the opposite direction as all the other moons of Neptune and opposite to Neptune's spin.

[@allanjmcpherson]

I understand why objects like Phobos and Deimos are "potato-shaped," but hearing that descriptor made me wonder. Why are potatoes "potato-shaped."

[@SevenDayGaming]

How could we forget Mars has moons? That's be like forgetting what happens when you try to teleport between them.

[@joshuaychung]

How do you forget about these two moons when the demons of the hell come through some sort of portal in these moons.

[@justintylerlee585]

Thanks for the great info, but that was way too complicated for me to follow at the moment. I'll just record some guitar playing instead.

[@Wulable]

What would the night skies of a planet in one of the galaxies in the 2349 cluster be like? Where I live I can see the milky way on a clear night. It would be amazing to see various galaxies criss crossing the sky.

[@xadahgla]

Piano!

[@TheHelghast1138]

Cool beans, baked potatos mooning us. 😎😎😎

[@baconatorbeastmode9741]

So confused3:00 how are asteroids wet if things are frozen?

[@billybobjohn8955]

Unfortunately Grunt never made it further than the outskirts of our planet, otherwise the question of the martian moons would have been answered by now.

[@mechadense]

2:27 en.wikipedia.org/wiki/Martian_Moons_Exploration

[@RandallJamesPeterson]

Do we know how productive in Star formation the Milky Way Galaxy was over 12 billion years ago. Maybe growth slows down when galaxies reach their teenage years.

[@othmantayach9449]

those are some good space potatoes

[@epicgamerboy-xj5hu]

they should add another madness combat character named phobos

[@korstmahler]

So long as we don't let the Union Aerospace Corp build research bases we'll be fine.

[@Reckec]

Unless as 2349 expanded it moved beyond our visible universe and its light will never catch us. What then Hank. Well,....

[@FrostyJonelSolid]

can we eat space potatoes on the space potatoes?

[@gawayne1374]

That's how we think our moon formed

[@JimmyCrackorn]

Astronomocla margins of error don't make me hopeful of news in my lifetime

[@derekriggs7659]

Asteroid belts? do asteroids wear belts to hold up their trousers?

[@muninrob]

Theory: Mars once had a moon of similar mass proportions of earth & it's moon, which was then struck by a large enough collider to split it in 2. Test: Retrieve samples from Phobos, Deimos, and Mars, then compare their isotropic ratios. Result: Unknown pending scientists with funding performing test

[@wurttmapper2200]

I think you should show us the math of how that could have happened

[@SauloGoki]

do not use outlines on the letters! Thought Café was the best

[@Myk3916]

Okay where's the trace gas Orbiter information??

[@Myk3916]

Yall Lagging...

[@stonedhomer621]

Science is the best. FOR SCIENCE!

[@whoeveriam0iam14222]

there are living things in that protocluster today that are looking at a proto Milky way wondering if there'd be life there

Knew it the whole time...

[@timrobinson513]

Are we sure they aren’t just holograms like our moon is?

[@axelNodvon2047]

Tim Robinson Lmao 😂 you think the moon is a hologram?? Dummy its just a giant flat cardboard attached by a long string.

[@jackielinde7568]

Well, the answer is "Yes", but only if you subscribe to the model that states that we are a 3D projection of a 2D image on the side of a black hole...

[@hjh1972]

Jack, "black hole"? Who gave you permission to talk about Uranus online?

[@Soupy_loopy]

No, we can't be sure that the whole universe is not just a simulation, I'm not even sure if this comment is real.

[@jackielinde7568]

Philotical, Your punishment for being both not funny and not relevant to the topic is to read this piece: en.wikipedia.org/wiki/Holographic_principle Next time, strive to be more like THis is not My real Name, who was both funny and relevant to the topic.

[@ryanvaros8827]

Getting closer. The true origins of mars' moons would *shock* you. ;^)

[@briankitchen6686]

Surely you meant ORANGES !

[@Soupy_loopy]

If the moon potatoes were broken up by gravity then the would be moon-tots

[@wellingtonsmith4998]

Sooo, we're bringing home not "The Waters of Mars" but the "Waters of Mars Moons." Well at least it's not Bowie Base One. I hope that a certain TARDIS owner is here to help contain this smaller Flood. Well done Japan.

[@Afinati]

[@wellingtonsmith4998]

like I said, Well done Japan. doing so much better than the USA.

[@shattywack]

There is diffidently something living over there in SPT2349-56. I'm going to go say hi. Wish me luck

[@freedomfirst5557]

So, why doesn't earth have many other captured rocks? I know the earth does have a couple but because of our size, shouldn't we have more?
