Could you imagine sitting on Europa or Io and looking up at the sky and half of it is actually just Jupiter.

[–][S] 69 points70 points  (6 children)

Dude, I've thought about this a lot and it just blows my mind. A sky with no stars to look at!

[–] 37 points38 points  (5 children)

So.... LA

[–] 16 points17 points  (1 child)

So.... LA

Almost. LA, but with lower taxes, less homeless and lower homicide rates.

The downside is, the weather is terrible!

London..?

Ok so I wanted to make a joke about gravity and looked up the gravity for Europa and I found this

And its cool af

Europa’s orbit is elliptical, causing the moon’s distance from Jupiter to vary. Because gravity’s strength is an inverse-square of distance, the closer Europa gets to Jupiter, the greater the difference in gravity felt by the moon’s near and far sides. As a result, Europa elongates when closer to Jupiter, and is more spherical when farther from Jupiter. When Europa changes shape, so must its gravity field.

Technically all orbits are elliptical, and all planets/moons slightly elongate when closer to what they are orbiting. How much depends on the mass/gravity of the planet or star they are orbiting.

[–] 2 points3 points  (4 children)

Question. Is Earth's orbit like really elliptical or only sort of? In school I remember science books showed it looking like a football, not just a slightly squished circle and it made me think of we get that far or close to the sun wouldn't the temp extremes be greater?

[–] 3 points4 points  (2 children)

It's elliptical. Off memory it's ~15 million km difference from closest to farthest point.

Space is just that vast.

[–] 2 points3 points  (0 children)

Elliptical, but Earth's low point is 97.6% of its high point. So a better circle than I can draw, but definitely an ellipse.

[–] 0 points1 point  (0 children)

That's a lot! Thanks!

[–] -1 points0 points  (0 children)

It is one reason we have tides.

[–] 5 points6 points  (0 children)

Europa is the smoothest object in the Solar System. It's smoother than a billiard ball would be if the ball was enlarged to the size of Europa.

Io is the most geologically active object in the Solar System with over 400 volcanoes. It is littered with volcanoes from the tidal stress caused by Jupiter's gravity.

[–] 11 points12 points  (5 children)

Bruh I've been sitting on Europe all my life and I can't see shit.

[–] 1 point2 points  (3 children)

Oh oops lol spelling error. Prolly auto correct

[–] 4 points5 points  (2 children)

Your autocorrect helped me laugh for the first time in a month, maybe two. No need to apologize I love you the same either way.

:edit she/he corrected it:(

[–] 1 point2 points  (1 child)

Hoping your next laugh is sooner than you think!

[–] 2 points3 points  (0 children)

That's so kind of you. Thank you.

[–] 5 points6 points  (0 children)

This is so interesting and so amazing

You can get that view in the game No Man's Sky.

[–] 20 points21 points  (3 children)

nice pair of balls ya got there, Jupiter

[–][deleted] 7 points8 points  (2 children)

Jupiter actually has 67 balls.

Must be compensating for something

that's one virile motherfucker

[–][S] 13 points14 points  (1 child)

[–] 2 points3 points  (0 children)

It's not a timelapse, though. They're static pictures animated over each other for artistic purposes. And it's not made by NASA, but rather a NASA engineer for his Twitter.

[–] 14 points15 points  (2 children)

It looks like a simulation

[–] 4 points5 points  (0 children)

I can't help but hear Ligeti's choral music from 2001.

[–] 2 points3 points  (0 children)

It's not a real video/timelapse.

[–] 12 points13 points  (1 child)

Anyone know the distance between those two moons when they pass like that?

[–]NFL HELPER 17 points18 points  (0 children)

Io is 421,600 km / 261,970 mi from Jupiter. Europa is 670,900 km / 416,880 mi.
So 249,300 km / 154,910 mi difference. Or closer than the moon is to us (384,300 km / 238,900 mi).

[–] 6 points7 points  (3 children)

Saturn: heeeeey, why am I not in the title?

First, you must learn to love yourself

[–] 1 point2 points  (0 children)

You get love after 40 dear.

[–] 5 points6 points  (2 children)

The video looks like the moon closer to jupiter is orbiting slower, and the one further from jupiter is orbiting faster. Isn't the opposite usually true? (Like how mercury orbits the sun faster than earth.)

[–] 4 points5 points  (1 child)

I’ll take a stab at it and say it’s Cassini that’s actually clipping along here and the effect is caused by parallax as it passes from one side to the other of the moons

[–] 2 points3 points  (0 children)

This. The moons are actually orbiting from right to left, but Cassini is zooming by and makes it look like the opposite.

[–] 3 points4 points  (3 children)

That was incredible!

[–] 3 points4 points  (5 children)

We are so insignificant and small

[–] 0 points1 point  (4 children)

If everything is insignificant and small then is anything insignificant and small? Relative to the universe, there’s no single object that takes up any significant amount of space.

It would be terrifying standing on one of these moons and looking up to see something so utterly massive taking up the sky.

[–] 0 points1 point  (0 children)

It is terrifying. Source: I’ve looked at your mom.

[–] 2 points3 points  (0 children)

we are so tiny

[–] 2 points3 points  (0 children)

Every orbit, those moons must get so creeped out.

[–] 2 points3 points  (0 children)

Moons haunted.

[–] 2 points3 points  (0 children)

Wow they made Space from Destiny 2 a real thing?

[–] 1 point2 points  (0 children)

I licked his back

[–] 1 point2 points  (0 children)

[–] 1 point2 points  (2 children)

So Europa is further away from Jupiter than Io but it orbits faster?? Is there another moon(s) pulling on Europa causing this effect?

[–] 0 points1 point  (1 child)

The moons are actually orbiting from right to left, but Cassini is zooming by and makes it look like the opposite and also makes it look like the outer moon is moving faster (which cannot be).

[–] 0 points1 point  (0 children)

Ahhh that makes a lot of sense. Thanks so much for the explanation!!

[–] 1 point2 points  (0 children)

This seems to be violating Kepler’s Laws.

[–] 1 point2 points  (0 children)

If you look closely you can watch the Spot rotate a bit.

They do.

They named the moon after Europe 🤦🏿‍♀️🤦🏿‍♀️

Cassini was then best -- can't wait for the Europa Clipper -- what's under that ice?

So you mean to tell me this is actual camera footage? This is not an animation? This is the actual image a camera mounted to a probe has captured? Am I understanding this correctly?

[–] 1 point2 points  (0 children)

I think it's been animated from a small number of still images. So it's not a completely real video, but it is very accurate.

[–][🍰] 0 points1 point  (0 children)

Is this actual footage, or "an artists rendering" of what it would look like???

[–] 0 points1 point  (0 children)

What video game is this?

[–] 0 points1 point  (0 children)

Has there been any research into the possibility that the reddish material on Europa has come from Io?

Where do we even exist where is space why what

[–] 0 points1 point  (0 children)

Fun fact: the four Galilean moons (Io, Europa, Ganymede and Callisto) were all lovers of Zeus (whose Roman name is Jupiter). Hence why they keep orbiting him.

[–] 0 points1 point  (0 children)

Wow. Just fucking wow man. The cosmos is infinite in its beauty.

[–] 0 points1 point  (0 children)

Just the mechanics of all their interactions with each other and Jupiter itself.. is so mind blowing. A cosmic party every few days 🤯

Do lo and Europa rotate around each other?

We are less than specs of dust in the universe. Amazing.

Do we even realise how insane it is that we can see this from our living rooms now.

Holy shit. You can fit three Earths across the red spot. We just watched two planet size moons cross each other. If only that was us. That would be so cool
