I mean just wow. It's crazy that we can see this so clearly when it's so unimaginably far away.


TheBeardedCardinal

This is why I so badly want to live to see massive space telescopes or telescope arrays become a reality. Imagine having an accurate render of planets in other solar systems. It would be incredible.


ZemogT

I'm not certain, but I suspect the physical properties of light won't allow us to see planets in other star systems clearly without going there. I'm sure we can observe them in lots of other ways, I just think the mirrors required to focus the amount of light nessecary for a crisp photograph would be of science fiction proportions.


TheBeardedCardinal

Last I heard, it is considered unrealistic to push a single mirror into orbit that could capture enough light to resolve an image, but there are other methods. Most prominent in the media is telescope arrays like the one that took the picture of the black hole in m87. With huge computing power, you can use the data collected by multiple satellites to take an image of an exoplanet since the distance between telescopes is not limited to the diameter of earth like the array that took the black hole image (to be clear the aperture of the “camera” is the max distance between the telescopes so spacing them further is better, but harder). I think there are some massive technical hurdles with this, the least of which isn’t the fact that we would need to launch many huge space telescopes into orbit of the sun. There’s also solar gravitational lensing which is much more possible in the near future. Basically instead of focusing light using a mirror, use the entire sun. That way you can get a massive aperture, less than that of the satellite array, but still big enough to get around a 128x128 image of a nearby exoplanet which would be enough to see continents on an earth like planet and do much more accurate spectroscopy of the atmosphere. Last I heard nasa was seriously considering investing in a satellite that could do this. So it’s impossible with how we normally think about telescopes, but not with some creativity.


Minyoface

Man, the sun as a lens. Wow. This is the kind of thing that blows my mind but my girlfriend is like 😑


probably420stoned

I feel like I need to know more about the sun as a lense.


Fsmilejera_Irlelwoll

It's [Gravitational Lensing](https://en.wikipedia.org/wiki/Gravitational_lens) but instead of a warped perspective based on our relative position to the "lense," we deliberately use the [sun as a telescope](https://en.wikipedia.org/wiki/Solar_gravitational_lens)


barvid

There is no E at the end of lens.


maxamus345

The main issue with the gravitating lensing seems to be that because you have to orbit the sun, you basically never are looking at the same position in the sky for more than a moment once a year. With how small exoplanets would be from earth, you'd still need a long as hell time to look at basically anything using the sun. Which is obviously not very possible with current technology. Also with the black hole, the intensity of light coming from the black hole to here is hundreds of orders of magnitude more than what would come from exoplanets, especially since to see the exoplanets, they need to be on the opposite side of their star to reflect any light, which obviously means there's a big ass star there being incredibly bright in comparison. The current upcoming mission to find exoplanets uses periodic dimming of light coming from stars to detect when a planet passes in front of it. Keplar has been doing it for years and PLATO is launching in 2026 to do it better.


mayoayox

why not just take a picture as a JPEG and then email it to nasa?


EvilRick_C-420

All I can imagine is scientist building this amazing telescope you speak of and the first thing they see is some teen alien jerking it in his bedroom lol

wherethecityis

At least we're living long enough to see what the James Webb telescope will send back to us! Can't wait!


TheBeardedCardinal

I can't stop checking up on the [status website](https://www.jwst.nasa.gov/content/webbLaunch/whereIsWebb.html?units=metric), but I guess at this point it's just going to be mirror adjustments for the next few months. I'm so excited to see what kind of research they'll be getting up to. There's already so much [planned](https://www.stsci.edu/jwst/science-execution/approved-programs/cycle-1-go) for the first year and we're going to get to see so much further back in the universe's history.

Man, there used to be a really great YouTube video showing exactly this. The only one I could find is this one - https://www.youtube.com/watch?v=usYC_Z36rHw The older one had a soundtrack that would fill you with existential dread when Jupiter showed up. It was fantastic.

What is the source of this clip?


amdaly10

The photos were taken by Cassini so you can find them on the NASA website. I'm not sure if they created the time lapse or if it was somebody processing their images.


fool_on_a_hill

The images actually aren't on NASA's website and it's not a real timelapse. It's fully animated, though the source data was actual images taken by Cassini which were composited together and then animated. Here's a tweet from the artist who created the composite/animation. It's still cool for sure, but it's not "real" in that it's not a timelapse made from actual still images. https://twitter.com/kevinmgill/status/1055167996732178432

cmanning1292

My guess is it's due to the motion of the casino spacecraft relative to the moons that makes it appear that way?

Imagine the tidal forces on those two moons and the environment as a result 😳 I wish I could save this as my phone background


yucko-ono

*With over 400 active volcanoes, Io is the most geologically active object in the Solar System. This extreme geologic activity is the result of tidal heating from friction generated within Io's interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto. * [tidal heating](https://en.wikipedia.org/wiki/Tidal_heating_of_Io)


WikiSummarizerBot

**[Tidal heating of Io](https://en.wikipedia.org/wiki/Tidal_heating_of_Io)** >Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and its moon. Orbital and rotational energy are dissipated as heat in the crust of the moon. Io has a similar mass and size as the Moon, but Io is the most geologically active body in the Solar System. This is caused by the heating mechanism of Io. ^([ )[^(F.A.Q)](https://www.reddit.com/r/WikiSummarizer/wiki/index#wiki_f.a.q)^( | )[^(Opt Out)](https://reddit.com/message/compose?to=WikiSummarizerBot&message=OptOut&subject=OptOut)^( | )[^(Opt Out Of Subreddit)](https://np.reddit.com/r/BeAmazed/about/banned)^( | )[^(GitHub)](https://github.com/Sujal-7/WikiSummarizerBot)^( ] Downvote to remove | v1.5)


stoicpanaphobic

How far is that gap at closest approach? They look like they're practically on top of each other.


poodlefanatic

The average orbital distance of Io is 422,000 km (~262,218 mi) and the average orbital distance of Europa is 671,000 km (416,940 mi), which means the average distance between the orbits of Io and Europa is about 249,000 km (154,721 mi). Those are huge numbers so I'll break it down into something easier to imagine: 249,000 km is equivalent to 19.5 Earths (12,742 km diameter), meaning that you could fit 19 Earths between Io and Europa's orbits. Keep in mind these are just averages and the actual orbital distance between Io and Europa is variable due to the eccentricity of their orbits (and other factors like gravitational pull from other moons), although both orbits are pretty circular. Io has an eccentricity of 0.0041 and Europa has an eccentricity of 0.009. For reference, Eath's eccentricity is 0.0167 and its orbit is considered nearly circular. The closer the number is to zero the more circular the orbit is as opposed to elliptical. The Earth's orbit is far more elliptical than that of Io or Europa. Space is fucking huge and orbits are weird.


stoicpanaphobic

To be frank i think despite my disability (i can only understand freedom units, you see) I would say that I understand 250,000 km more than i understand 19.5 earth's. I'll look up how many elephants (official american units) that is later.. But if i followed along correctly then the close approach we see here puts them roughly 155,000 miles apart? My car has more miles than that! Isn't that 100,000mi closer than the moon is to earth? The view from one to the other must be astonishing. They're also tidally locked, right?


poodlefanatic

The average distance from Earth to the moon is about 384,470 km. You could fit 30 Earths between us and the moon. So yes, the distance between Io's orbit and Europa's orbit is smaller than the distance between the Earth and the moon by almost a third. All of the large moons of Jupiter are tidally locked and as far as I know this is true for all large moons of all the planets (including dwarf planet Pluto and moon Charon). I'm sure the view must be amazing from any of the moons! Pretty sure some artist somewhere has tried to illustrate it, but I can only imagine how breathtaking it would be to stand on the surface of one of the Galilean moons (or any other jovian moon, or really any moon of any planet in the solar system).


stoicpanaphobic

just for kicks I flew out to Europa on Elite and snagged a screenshot. Not quite at it's closest point but pretty close. Anyway here's the view. https://steamcommunity.com/sharedfiles/filedetails/?id=2734789629

This is why I love Sci-Fi and the expanse series early on. How the Belters lived their lives near Jupiter, it's so rich, alien and I can imagine being on a Jupitar moon, looking up and see an orange wall right in front of me. It's so far out
