A tale of two Saturns. The one from Hubble shows visible light, the one from JWST shows infrared.

They're taken 3 months apart, so they also show Saturn's shifting angle relative to Earth. A welcome double dose of beauty.

NASA Webb, Hubble Share Most Comprehensive View of Saturn to Date

NASA’s Webb and Hubble Space Telescopes have teamed up to capture new views of Saturn, revealing the planet in strikingly different ways.

But wait! Here's another perspective on Saturn. This JWST image shows how auroras on the planet heat the atmosphere, which drives winds, which generate electrical currents, which help create more auroras...

It's an endless dynamic cycle that we've just discovered.

Image shows the asymmetric temperature structure revealed in the paper, as it was observed from JWST. These are offset from where the currents flow into and out of the planet, but ultimately, the winds generated by this temperature offset are what drive those currents.

Scientists solve decades-long mystery about why Saturn appears to change its spin

Researchers at Northumbria University have used the most powerful space telescope ever built to answer one of the longest-standing puzzles in planetary science – why does Saturn appear to spin at a different speed depending on how you measure it?

Hiti

हिति , in Nepāl Bhāṣā, is the word for a shared community water tap. Even in modern Newar cities, these ancient structures still pour out fresh mountain water piped through ancient underground filters and conduits. They are a place to wash, to talk, to drink, to meet the locals: a nourishing, refreshing social-ecological place.
