Found a brown widow spider in my garage. After some pictures, it is no longer in my garage….
A gross spider hanging upside down on a crappy web. I’m not kidding, she did a really lousy job building that thing. It was awful, like she was drunk when she made it. Dumb spider. Either way, I introduced her to the bottom of my shoe so she is no longer among the living.

Comet C/2025 R2 Swan on October 24th. This is processed from 14.5 minutes of integration across 28 images in PixInsight and Photoshop.

New profile pic: Me trying (and probably failing) to look cool in shadow.
A wall of talc and bits of schist. Dry shrubs at the lower left and upper right corners. The shadow of a person, me, is on the wall. The shadow is wearing a booney hat because his stupid bald head burns super fast in the sun. Fun fact about that: When I was really little I was afraid of bald men. Now I am one. They shaved my head when I went to Marine Corps boot camp (I was 19) and it never quite grew back completely.

While the telescope was doing its thing, I used another camera to look back towards Santa Clarita, California, and the Big Dipper.

Comet C/2025 A6 Lemmon, 48.5 minutes of exposure across 97 images taken from Bear Divide in Los Angeles. This is the first time I’ve processed a comet observation like this so I had to do some quick learning and experimentation. Hopefully I’ll improve on this in the future.

MAHLI and MastCam images taken by the Mars Curiosity Rover as a before & after of the new “Valle de la Luna” drill site.

The first two images are using MAHLI on Sol 4690 and are white balanced. The third is MastCam used post-drill on Sol 4693.

A reprojected view of Jupiter centered near the border with the Northern Filamentary Region. This uses image data taken by NASA’s JunoCam during the Perijove 26 flyby in April 2020. I created a simulated terrain relief to provide a sense of vertical scale to the cloudtops.

Here’s another one from the United Arab Emirates’ Hope Mars Mission orbiter taken on February 10 2025. This is centered over the northern hemisphere Utopia Planitia, a vast and flat impact basin.

Check out that small (from our perspective) line in the southern hemisphere leading to a crater. That crater is Gale Crater, a once flooded crater centered with Mount Sharp. That’s the home of NASA’s Mars Curiosity Rover, still performing amazing science and making discoveries after all these years. CU/LASP EMM/EXI ITF/Kevin M. Gill

Went hiking last night in an area with plentiful albite-quartz-muscovite schist and some actinolite-albite schist. I took a few small rocks to document them but nothing particularly impressive. All this is from marine trench sediments subducted with the Farallon plate, metamorphosed, and uplifted.

This is the image I think he started with. Navaneeth went and provided additional processing on top of it.
