“Restructuring” because the Whitehouse and their allies choose destruction of all the good parts of the United States federal government because it won’t make them a personal profit. Also, they hate science, people who do good things for everyone instead of for them only, and actual reality.

I captured Comet Lemmon early October 7, 2025. Using my 300mm Ceravolo telescope and CCD camera. About 30 minutes of total exposures using LRGB filters. The tail is much longer than shown in this 1 degree field of view.

A beautiful new comet graces the northern sky. Comet Lemmon has a bright green comma and long ion tail

#PPOD: What do you see? A fossilized head of a fish gasping for air in a long-dried-up lake, or maybe that's a worm on Dune coming out to hunt. In actuality, NASA's Mars Perseverance rover acquired this image using its Left Mastcam-Z camera on Oct. 17, 2024. Credit: NASA/JPL-Caltech/ASU 🧪 🔭

An unusual rock rests on the surface of Mars. It's a domed rock with a crack going straight up from the ground. A much smaller rock is off to the left.

Easy pick of the week this time -- SpaceX's IFT-11 launch tmrw (Monday). That's also a federal holiday. Otherwise it's pretty quiet while waiting for a solution to the government shutdown.
