#Stunning #pictures released today by the #European #Space Agency of #galaxies and a globular cluster.

No, these #images are not from #JWST nor #HST, but from #ESA's newest mission: #Euclid.

These images are combining data from the 2 instruments onboard: VIS, and #NISP that was build at #LAM.

Enjoy ! 🤩

Hey Mastodonians,

A new 'Remembering Cassini' episode is now posted on "Coming of Age in the Solar System".

It's called 'Entering the House of Saturn' ... which is what Cassini did 20 years ago today.

Mars helicopter Ingenuity completed Flight 71 on Jan 6.

But Ingenuity made an emergency and safe landing 35 seconds into the planned 125 second flight.

NASA states that "the relatively featureless terrain it flew over (sand ripples with few or no rocks) proved to be a challenge for its navigation system."

This sounds different than the emergency landing during flight 53 on July 22, 2023, when the ‘LAND_NOW’ software was triggered by a loss of image frames.

Yes, Safari 17 supports JPEG XL. On macOS Sonoma, macOS Ventura and macOS Monterey, as well as iOS, iPadOS, watchOS, and soon, visionOS.

We also added HEIC — especially for web apps that want to let users edit photos directly from the camera.

Calling all!

I have very irregularly sampled temporal data (hint: think Enceladus' plume). The usual least-squares-fitting & spectral analysis methods are giving my collaborators & me grief.

Wondering: Are there yet available any such data-analysis algorithms based on AI?

🆕 blog! “What's the smallest file size for a 1 pixel image?”

There are lots of new image compression formats out there. They excel at taking large, complex pictures and algorithmically reducing them to smaller file sizes. All of the comparisons I've seen show how good they are at squashing down big files. I wanted to go the other way. How good are modern codecs at …
