#UMPlus - Spiral Galaxy NGC 3511

universomagico.net/2025/05/gal

This majestic spiral galaxy is NGC 3511, imaged in this image by the Hubble Space Telescope. It lies 43 million light-years from the Milky Way and is located in the direction of the Crater constellation. From our perspective, NGC 3511 is tilted about 70°, an inclination intermediate between face-on galaxies, which.....

Deimos Before Sunrise
" Deimos takes 30 hours and 18 minutes to complete one orbit around the Red Planet. That's a little more than one Martian day or sol which is about 24 hours and 40 minutes long, so Deimos drifts westward across the Martian sky. About 15 kilometers across at its widest, the smallest of Mars' two moons is bright though. In fact Deimos is the brightest celestial object in this Martian skyscape captured before sunrise by Perseverance on March 1, the 1,433rd sol of the Mars rover's mission. The image is a composed of 16 exposures recorded by one of the rover's navigation cameras. The individual exposures were combined into a single image for an enhanced low light view. Regulus and Algeiba, bright stars in the constellation Leo, are also visible in the dark Martian predawn sky."

Echoes from the Deep / Echi dal Profondo for #spookysaturday episode 10

"How many times do I have to do this?", you wonder. This is a futile mission. There's nobody but us. You've spent years studying, training, waiting to get out there into space. To explore new frontiers, see distant lands, discover if we are really alone, and instead you've ended up in this cramped room pinging out messages every day.
The message is always the same: "This is Terra. Is anyone out there?" And the answer is always the same - silence.
You type it out again. What is this now – the 6th or 7th year? Oh, it doesn't matter. Send.
The screen turns blank. Quelle surprise. Lather, rinse, repeat. Time to go to lunch. You start putting on your jacket when you hear the ping. The computer lights up.
"ENOUGH" fills the screen.
You try to triangulate the message – one of your coworkers has obviously decided to be a smartass today. A welcome break from the monotony. but unfortunately for them, all activity must be reported.
The signal isn't coming from in here or out there. It's coming from underground. Deep underground. Way way too deep underground.

(That's another reason to say no to fracking kids!!
This photo is one of my first astrophotography photos - so be gentle with it please. 😂✨)

Big Dipper Test Photo from Homemade Star Tracker
Placitas, NM

A little over a year ago I began this project to build what's called a "barn door" tracker driven by an Arduino and stepper motor. Luckily a neighbor has a hobby wood shop and was eager to help. The results last year left much to be desired, but I have spent a week or two this spring making refinements. It's far from perfect, but should do for wide sky photography.

Also many thanks to @KrajciTom and @akkana for their technical help and encouragement.

I used free, open source software Siril for processing the eleven 59 second exposures (and five 59 second "darks" to remove the hot pixel artifacts from the camera sensor) in this short test sequence. I used curves & levels in GIMP as a final step.

Deimos
NASA Science Editorial Team

Deimos is the smaller of Mars' two moons. It's 9 by 7 by 6.8 miles in size (15 by 12 by 11 kilometers). Deimos orbits Mars every 30 hours.

Quick Facts

Deimos is the smaller of the two Martian moons and is less irregular in shape.
Like Phobos, Deimos is a small and lumpy, heavily cratered object. Its craters are generally smaller than 1.6 miles (2.5 kilometers) in diameter, however, and it lacks the grooves and ridges seen on Phobos. When impacted, dust and debris will leave the surface of the moon because it doesn't have enough gravitational pull to retain the ejecta. However, the gravity from Mars will keep a ring of this debris around the planet in approximately the same region that the moon orbits. As the moon revolves, the debris is redeposited as a dusty layer on its surface.

Deimos has a thick regolith, perhaps as deep as 328 feet (100 meters), formed as meteorites pulverized the surface.

Deimos is a dark body that appears to be composed of C-type surface materials, similar to that of asteroids found in the outer asteroid belt.

How Deimos Got its Name

Deimos was discovered on Aug. 11, 1877 by Asaph Hall. Hall named Mars' moons for the mythological sons of Ares, the Greek counterpart of the Roman god, Mars. Deimos, whose name means dread, is the brother of Phobos.

Explanation:
Deimos takes 30 hours and 18 minutes to complete one orbit around the Red Planet. That's a little more than one Martian day or sol which is about 24 hours and 40 minutes long, so Deimos drifts westward across the Martian sky. About 15 kilometers across at its widest, the smallest of Mars' two moons is bright though. In fact Deimos is the brightest celestial object in this Martian skyscape captured before sunrise by Perseverance on March 1, the 1,433rd sol of the Mars rover's mission. The image is a composed of 16 exposures recorded by one of the rover's navigation cameras. The individual exposures were combined into a single image for an enhanced low light view. Regulus and Algeiba, bright stars in the constellation Leo, are also visible in the dark Martian predawn sky.
