Truly, Robert McCall was a master at his craft. I never get tired of his artwork. Image found via x-ray delta one.

Yeah yeah, I know I recently posted a Jupiter photo, but with imagery like this coming from Juno, I really don’t care. If the internet’s space content is slanted heavily towards Jupiter, so be it.
“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said [Scott] Bolton. “On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system — one that every school kid knows — Jupiter’s Great Red Spot. If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”
(Emphasis mine.) Bring on the fire hose, I say!!

I do love aurora photos, but this one combines them with two more of my favorite things: Iceland, and volcanos!
You don’t always see a scene this beautiful when you hike to an ancient volcano — you have to be lucky. When the astrophotographer realized that auroras were visible two-weeks ago, he made a night-time run for the top of the caldera to see if he could capture them also reflected in the central lake. When he arrived, he found that … the northern lights were even brighter and more impressive than before! And his image of them is the featured 13-frame panoramic mosaic. The crater lake in the center is called Kerid (Icelandic: Kerið) and is about 3,000 years old. The aurora overhead shows impressive colors and banding, with the red colors occurring higher in the Earth’s atmosphere than the green. The background sky is filled with icons of the northern night including Polaris, the Pleiades star cluster, and the stars that compose the handle of the Big Dipper.
Yeah, this is yesterday’s APOD, but I don’t recall having seen the Spaghetti Nebula before, and the picture is simply fantastic. Enjoy your weekend!
Explanation: It’s easy to get lost following intricate filaments in this detailed image of faint supernova remnant Simeis 147. Also cataloged as Sharpless 2-240 it goes by the popular nickname, the Spaghetti Nebula. Seen toward the boundary of the constellations Taurus and Auriga, it covers nearly 3 degrees or 6 full moons on the sky. That’s about 150 light-years at the stellar debris cloud’s estimated distance of 3,000 light-years. This composite includes image data taken through narrow-band filters, enhancing the reddish emission from ionized hydrogen atoms to trace the shocked, glowing gas. The supernova remnant has an estimated age of about 40,000 years, meaning light from the massive stellar explosion first reached Earth 40,000 years ago. But the expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star’s core.
