I saw Callisto yesterday through my telescope. Wasn't anything more than a point of light beside the gas giant along with other moons. But still fascinating to think about it, the light reflected from the surface of another world travelled millions of kilometres only to enter my telescope and go inside my eye. Surreal.

[@ant8724]

Indeed, very surreal!

[@dhilgersom]

I wonder about her surface looking so similar to our moon. Our moon rings like a bell.

What type of a telescope woud you need to have to see anything in space and how much woud it be?

[@arjenbij]

@@KING-ef2wm Get a small telescope if you want to dive into amateur astronomy. Celestron has one called the "first scope" with some bigger analogs as well. These newtonians will make you able you be able to watch the moon, planets like jupiter and it's galilean moons, venus, mars, and the rings of saturn.

[@adarsh4764]

I still remember when at age of 10, my dad gave me an Encyclopaedia where I first time knew that other planets of our solar system have moons too. And out of which I found Callisto to be the most beautiful and fascinating to me as it had so much spots on its surface. I literally thought Callisto as a gem stone moon as it looked like all the spots are as if shining like gem.❤️

[@TheButtflyEffectAnimator]

do you remember the name of the encyclopedia? i wanna see the picture of Callisto in there

[@kakarroto007]

*Fun **-Fact-** Myth:* Callisto was a nymph who was seduced by Zeus, when he took the form of Artemis, whom she was in love with. They had a son, Arcus, who became a great hunter. Artemis kicked her to the curb, and Hera also found out and asked to speak to her manager. Irate, Hera transformed Callisto into a bear. Many years later, Arcus was hunting a bear, not kowing it was his mother. Seeing this all play out from Mount Olympus, Zeus blew Arcas and Callisto far away from each other and they each became constellations. Callisto became Ursa Major (the bear), and her son became Boötes (the herdsman).

[@fnamelname9077]

I dunno man, you might have crossed out "fun". That's harsh! XD

[@thenasadude6878]

[@Beryllahawk]

Callisto was the first Galilean moon that I ever wanted to learn about actually!!! Granted, that was because of a sc-fi novel: Anne McCaffrey's wonderful Talent series! In those books, one of the major characters, a powerful psionic called The Rowan, lives on Callisto Station. In the original short story that predated the novels, her Tower was situated on the moon itself; for years and years I loved to sit and imagine being in that place, in a domed settlement - not terribly large, of course...and being able to just look up and see Jupiter looming "overhead" as it were! The station was indeed used as a waypoint in the world of those books, though the methods of transport were downright fantastical, haha! This was a great video! I really enjoyed seeing more details about this moon - and you're right, it should not be forgotten. It has too many things to teach us, and too many possibilities that it could open for us!

[@somewherenorthofstarbase7056]

Centuries from now, when there is a human base on Callisto, hopefully this inspiring video will be remembered and honored by naming the settlement Astrum Base.

The Callisto I knew about as a young boy was the green Jovian alien in the Major Matt Mason series of action figure toys. ☺️ But after learning in school that Callisto was also a moon I started asking my folks about the planets & moons.
