I know we did Fridays last time. The weather was bad, so I kinda forgot about it. The transparency tonight is looking suboptimal, and, given my options, I might just settle for hitting some binary stars. My best view is of the eastern sky, and most everything there right now is faint fuzzies, so I don’t have especially high...

Eight billion people are about to disappear in this snapshot from space taken on 2022 November 21. On the sixth day of the Artemis I mission, their home world is setting behind the Moon’s bright edge as viewed by an external camera on the outbound Orion spacecraft. Orion was headed for a powered flyby that took it to within...

Maybe this lives in showerthoughts, but Chile has a lot of large telescopes and you often hear its because they’re on mountains above clouds. The border with Argentina goes through the middle of the mountains so it seems like it should be a good spot for telescopes too....

I have been searching online for information, but i fail to find anything concrete....

NGC 1333 is seen in visible light as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus, it lies at the edge of a large, star-forming molecular cloud. This telescopic close-up spans over two full moons...

Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy’s two spiral arms extending from a pronounced central bar give it a hook-shaped appearance in this deep and colorful image, with foreground stars scattered across the...

In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured here in the center are two of the most prominent reflection nebulas - dust clouds lit by the reflecting light of bright embedded stars. The more famous nebula is M78, in the image center, cataloged over 200 years ago. To...

I forgot what settings I used but I used pro-photo mode and enhanced some settings such as brightness and contrast. I did not use any AI. This was before the big AI boom occurred. I just was lucky enough to get clear skies without any light pollution.

Very faint planetary nebula Abell 7 is about 1,800 light-years distant. It lies just south of Orion in planet Earth’s skies toward the constellation Lepus, The Hare. Posing with scattered Milky Way stars, its generally simple spherical shape about 8 light-years in diameter is revealed in this deep telescopic image. The...

Cycle 25 solar maximum made 2025 a great year for aurora borealis (or aurora australis) on planet Earth. And the high level of solar activity should extend into 2026. So, while you’re celebrating the arrival of the new year, check out this spectacular auroral display that erupted in starry night skies over Kirkjufell, Iceland....

As we're approaching the summer solstice, I'm going to harden my heart to the fact that it won't be getting nice and dark until, like, ten where I'm at. What are you guys going to be looking for tonight? If you're not going out, do you have any recommendations?...

This might be interesting to people here. It is an unfinished series of articles that cover each major stage of the big bang era timeline....
