M78 // Capturing Ancient Photons
A beautiful series of reflection nebulae make up M78. These reflection nebulae, like their name suggests, contain little ionized gas and primarily reflect the light of nearby stars. In this case, it is only two stars' light that the gas is reflecting despite containing a few hundred young stars within.

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.)

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.
The monsters that live on the Sun are not like us. They are larger than the Earth and made of gas hotter than in any teapot. They have no eyes, but at times, many tentacles. They float. Usually, they slowly change shape and just fade back onto the Sun over about a month. Sometimes, though, they suddenly explode and unleash energetic particles into the Solar System that can attack the Earth. Pictured is a huge solar prominence imaged almost two weeks ago in the light of hydrogen. Captured by a small telescope in Gilbert, Arizona, USA, the monsteresque plume of gas was held aloft by the ever-present but ever-changing magnetic field near the surface of the Sun. Our active Sun continues to show an unusually high number of prominences, filaments, sunspots, and large active regions as solar maximum approaches in 2025.

Going for a walk. Apollo 17 astronaut Ronald Evans leaves to the spacecraft to retrieve film cassettes from the Service Module, Dec 1972. Mr. Evans was Command Module Pilot & orbited the moon a record 75 times during the mission. He holds the record for most time spent in lunar orbit at just shy of 148 hours. He is the last human to orbit the moon solo. A historic figure in space pioneering.
