Okay, I literally said "oh my god", not oh-em-gee.

That's fantastic. Thanks for posting.

What are the crop circles and alien designs on the moon? And what are the sparks on Jupiter? Lightening?

Also, does it actually look like this? I mean if I went there and looked at it with my human eyes, is that what it would look like? I'm asking because it seems like often with space things the cameras they use capture things we can't see and then they colour the picture somehow. Like those Star-Trek-esque nebula pictures are coloured, I think.

Here is the information on the JunoCam. I don't know if they're mixing the near-infrared in with the visual light strips or not for this video, but it would likely look much like this to the human eye. Jupiter is famously really fantastic even through backyard telescopes.

My god, it's full of s-t-a-r-sssss!

Oh, wait, that's just dust specks on my monitor, that show up really nicely when the dark side of Jupiter has blacked everything out.

Other than that, though, the video was really great. You can go to Nasa's web site and view all kinds of photos & data from the Juno mission. But it takes something more for it all to make much sense to most of us.

Are those lightning flashes in the cloud tops? It looks like lightning flashes in the cloud tops, which is so spectacular and sublime as to be almost unbelievable.

I watch the 4 moons of Jupiter everynight annndd tonight it's cloudy, never seen it do cloudy, comparitive wise to the last two years, this summer I'm down 32% in my little Jupiter sketch book.

It has a touch of Kubrick. Like a dash.
I never seen anything so stunning, I watched both twice, Vengelis works here. I love how Juno dips then picks up that sling shot, is that right?, and wish you were here not so much an aloud OMG, though I did that, like most when you first see the rings of Saturn for the first time. I love Callisto, just always like a wide arm. I believe Ganymede was very close to Europa the other night but that's just angle I think.
That lighting what not, oh going to make extracting more difficult, more rubber mats.
The specs on that craft is impressive for $1.1 billion.

The continued existence of that craft is fucking amazing, given that its radiation shields were proven to be Not Enough and they adjusted to a long orbit instead of the shorter, closer-in orbits they had initially planned. They keep sweeping the thing back through the magnetosphere, and it keeps surviving.

I don't know if they would have visited Ganymede like this under their initial plans for studying Jupiter.

I love how NASA keeps missions going and going and going... Our robot friends are really really amazing!

Wow. Had no idea Jupiter was so Van Gogh-esque.

So the lightning was added by the animators. Has Juno actually taken pictures of lightning at some point, or is it just conjecture that there would be lightning?

Thanks for sharing this! Amazing video!

I seem to recall the initial design for Juno didn't include a camera, and they added one later to increase mission interest. (Oh yeah, looks like that was the case. Glad they did!)

Wonder how the LEGO minifigs on board are holding up?

Now this is the kind of space news I can use. Thanks for posting!

From the website:

“Using information that Juno has learned from studying Jupiter’s atmosphere, the animation team simulated lightning one might see as we pass over Jupiter’s giant thunderstorms.”

So it doesn’t sound like they’ve recorded the lightning flashes, but are assuming they must exist because of other data they have about the storms (composition, dynamics, etc.).

clavdivs: I watch the 4 moons of Jupiter everynight

I highly recommend this to anyone who will listen. The four large moons are barely beyond what the unaided eye can see, so even cheap binoculars will reveal them. They just look like tiny stars, but they are obviously associated with Jupiter, and move around from one night to the next. Finding Jupiter is easy because it is brighter than any star in the night sky, but if you have any trouble Stellarium is great.

I love how Juno dips then picks up that sling shot, is that right?

That's Kepler's 2nd law in action. Another way to look at it is that as an object falls from the highest point in its orbit towards its lowest point, it gains speed, converting gravitational potential energy into kinetic energy. When it coasts back up from the lowest point to the highest point, the reverse happens. The orbital energy remains constant. Juno's orbit is much more eccentric than the one shown in the wikipedia animation, so the effect is much more pronounced than shown there. (This stuff becomes intuitive after playing Kerbal Space Program for a while.)

hippybear: its radiation shields were proven to be Not Enough and they adjusted to a long orbit instead of the shorter, closer-in orbits they had initially planned

As I understand it, the reason they kept the longer orbit was because of a problem with the main engine: NASA’s Juno Mission to Remain in Current Orbit at Jupiter

I never realized how beautiful Jupiter is. Just amazing. Thanks so much for sharing.

I got goosebumps watching that. Thanks.

clavdivs: I watch the 4 moons of Jupiter everynight

I highly recommend this to anyone who will listen.

I have an old Meade 6 inch Maksutov-Cassegrain spotting scope I picked up at a yard sale years ago. It lacks an astronomical mount, which is a bother as the crescent moon more than fills the view and moves so fast.

But as the shadowed craters of the crescent moon are so far more beautiful to see than the full orb's washed out fullness, it's worth the effort.

As are the planets, Jupiter and Saturn especially with the four Galilean moons of the former and the rings of the latter. There is something so cool at looking at a tiny ringed dot and knowing that the image is amplified mechanically rather than electronically.

Just after sunset two nights ago, I saw the gleam of Mars and Venus low in the sky through a tree branch a block away. On the old free Google astronomy app Sky Map, they were overlapping spheres in conjunction.

To the naked eye, they were one planet. But through the Meade, they were two bright overlapping dots, one red, one white -- just like on Sky Map. I was blown away by that quick glimpse.

Someone on line was calling the video "the starship captain's view."

Juno has a Waves instrument, to detect a wide range of radio frequencies and also magnetic fields.

Here's a map of detected lightning on Jupiter.

Long distance detection on earth:

The interesting lightningmaps.org has real time lightning strikes. Precise timing of the received radio static at multiple stations determines the lightning location.

Here's the eastern USA map, with a clicking noise for each strike. And the lines converging on the strike are drawn from each detecting station, with the detection often reaching S America or Europe. Click the antenna icon at the top right to turn off the lines. Zoom way in to see the thunder sound waves propagate out! When viewing your area, save the current URL to keep that same view. You might need to toggle the speaker icon to hear the clicks.

Jovian lighting imaged by Juno.

This is not a standard imaging telescope, but a heavily-radiation-shielded camera usually used for navigation purposes.

Came for the storms; not disappointed! Rather enthralled. Thank you for the post, hippybear. Space is AWESOME.

🎶let me see what spring is like on Jupiter and Mars🎶

I was really happy to see the news this morning that they had successfully switched Hubble to the backup computer & that it would resume observations soon. How those magicians figured that out is beyond my comprehension, even after reading the details. Wizardry!

The lightning maps are telling. There is dead air all over the West, no energy. What have they done?

I wish the garage sale Zen would have landed Maksutov-Cassegrain Karl but for $5, 3 years ago I found a simple 20x Galileo.
As swr wrote, a good set of binocs will do but I get to see some color out of Jupiter. So I'm still non-sideral. Got to see Neptune, little thimble of eeking bluish light. The bestest time was showing my grand niece the moon, oh how that take, that double look and look back at the moon. She commented on the "heat ring, like the "parking lot" and said the moon is like a dusty golf ball. Then Saturn which just seems tiny a "moon ring" and Jupiter which brings delight. I'm not sure if the world became a bit smaller or larger perhaps both.

moon is hazy and orange tonight. Nothing is getting through, drats.
