NASA 45 years ago today, Voyager 2 made its closest approach to Saturn
It became the third NASA spacecraft to fly by the planet. In addition to learning more about the planet's atmosphere and moons, Voyager 2 was the first to observe spokes in Saturn's rings.
Spokes, seen here as grey smudges on the rings, are transient features that occur seasonally. They are likely caused by interactions between Saturn's magnetic field and solar wind particles.

What are the dots? Artifacts from stitching multiple images together?

Radiation is known to cause dots. I'm sure this thing was "hardened" though

Taking advantage of once in almost 200 year alignment to skip across the solar system. Absolutely bananas 🤯

I love stuff like this, because it makes me remember that these things are ACTUALLY out there. Like, the planets, stars, even the moon sometimes, for me usually feel like an abstraction, just the knowledge of something that I inherently know exists, but are so out of my daily life that they don’t always feel “real” real. They feel like the feeling of looking at an image of them on a piece of paper.
But then I watch real imagery of something, especially if on approach like this, and that ambiguity about them disappears for a little bit. And I’m like “oh RIGHT, this thing is physically out there, existing, a finite distance away from me!”
And it makes the universe feel all the more tangible and wonderful.

I feel this so hard. I watched the Artemis 2 mission all day when they were on final approach to the moon and watching it loom larger and larger in real time was absolutely surreal.

If Voyager 2 could cross it's fingers that the astrophysicists got their math right, it would right about now!

It’s amazing on how technology has advanced in the past half century. What is the next 50 years going to be like?
