I'm having too much fun taking Skye sky photos on a cloudless winter's night. From May until the end of July it doesn't get dark enough for stars. (Pixel 5 in Night Mode / Astrophotography AI on.)

Saturn has a mysterious hexagon at its north pole that has refused to give up its secrets, probably because neither Voyager 1 nor Cassini was able to plunge that deep and survive. Harvard scientists Rakesh Yadav and Jeremy Bloxham might have finally started to figure out what causes this peculiar feature. They believe that vortexes occur at the planet’s north pole because of atmospheric flows deep within the gas giant, and that these vortexes pinch an intense horizontal jet near the equator—which is what warps the storm into a hexagon. It still looks unnatural though.....!!!

New pics of Io just dropped

More are over here at NASA's Juno probe site.

Whirlpool Galaxy M51a was the very first galaxy classified as a spiral galaxy.

The photos that NASAHubble & NASAWebb took of The Pillars of Creation inspired me deeply. I had to draw what I saw in the formation: A hand reaching into the universe. What an accomplishment for humankind and what a symbol for exploration and knowledge. Credit 2nd image: NASA

Y'all, the world is sleeping on what NASA just pulled off with Voyager 1

The probe has been sending gibberish science data back to Earth, and scientists feared it was just the probe finally dying. You know, after working for 50 GODDAMN YEARS and LEAVING THE GODDAMN SOLAR SYSTEM and STILL CHURNING OUT GODDAMN DATA.

So they analyzed the gibberish and realized that in it was a total readout of EVERYTHING ON THE PROBE. Data, the programming, hardware specs and status, everything. They realized that one of the chips was malfunctioning.

So what do you do when your probe is 22 Billion km away and needs a fix? Why, you just REPROGRAM THAT ENTIRE GODDAMN THING. Told it to avoid the bad chip, store the data elsewhere.

Sent the new code on April 18th. Got a response on April 20th - yeah, it's so far away that it took that long just to transmit.

And the probe is working again.

From a programmer's perspective, that may be the most fucking impressive thing I have ever heard.
