Very cool.

"The connection between ancient texts, celestial imagery, and modern astronomical findings continues to provide new insights into how ancient civilizations viewed the cosmos...illustrating how cultural depictions of the sky were deeply intertwined with both the practical and spiritual life of ancient Egypt."

Im Übrigen:
"Others argue that where an object is located or what it is made of do matter and there should not be a concern with dynamics; that is, whether or not an object sweeps up or scatters away its immediate neighbors, or holds them in stable orbits."
Astronomen scheinen wie Politiker zu sein: können sich nicht einmal auf das Grundlegendste einigen!
Und es kommt noch besser:

We are bulding the Milky Way LEGO set, and it keeps remindig me of this meme :D

Lyrids meteor shower: one-day--past-peak report.
This is the only image I noted, out of over 1,000 taken through the night, that shows a Lyrid. And Murphy's Law dictates that it be partly hidden by a tree.
Note the Milky Way rising out of the trees in this wide-angle view.

Almost the Center of our Galaxy
-----------------------------------------------
I really wanted to get as close as possible to the milky way center as possible for my latitude.
This was as close to the horizon as possible before dawn.
It was worth the struggle of waking up at 3:30 AM at this remote location, because I got to test my new portable wide-angle setup for the first time :)

This zoom video sequence starts with a broad view of the Milky Way. We then dive into the dusty central region to take a much closer look. There, a swarm of stars orbit around an invisible object: a supermassive black hole, 4.3 million times that of the Sun. As we get closer to it, we see these stars, as observed by the NACO instrument on ESO’s Very Large Telescope (the last observation being from 2019). As we zoom in further, we see stars even closer to the black hole, observed with the GRAVITY instrument on ESO’s Very Large Telescope Interferometry in mid-2021.

An Immersive Visualization of the Galactic Center
Video Credit: NASA, CXC, Pontifical Catholic Univ. of Chile, C. Russell et al.
Explanation:
What if you could look out from the center of our Galaxy -- what might you see? Two scientifically-determined possibilities are shown in the featured video, an immersive 360-degree view which allows you to look around in every direction. The pictured computer simulation is based on infrared data from ESO's Very Large Telescope in Chile and X-ray data from NASA's orbiting Chandra X-ray Observatory. As the video starts, you quickly approach Sgr A*, the supermassive black hole in the Galactic center. Then looking out, this 500-year time-lapse simulation shows glowing gas and many points of light orbiting all around you. Many of these points are young Wolf-Rayet stars that have visible hot winds blowing out into surrounding nebulas. Clouds approaching close become elongated, while objects approaching too close fall in. Toward the video's end the simulation repeats, but this time with the dynamic region surrounding Sgr A* expelling hot gas that pushes back against approaching material.

The featured picture shows an image of our Milky Way's center by the MeerKAT array of 64 radio dishes in South Africa. Spanning four times the angular size of the Moon (2 degrees), the image is impressively vast, deep, and detailed. Many known sources are shown in clear detail, including many with a prefix of Sgr, since the galactic center is in the direction of the constellation Sagittarius. In our galaxy's center lies Sgr A, found here in the image center, which houses the Milky Way's central supermassive black hole. Other sources in the image are not as well understood, including the Arc, just to the left of Sgr A, and numerous filamentary threads. The inset image shows a small patch recently imaged in infrared light with the James Webb Space Telescope to investigate the effects of magnetic fields on star formation.

Explanation:
What's happening at the center of our galaxy? It's hard to tell with optical telescopes since visible light is blocked by intervening interstellar dust. In other bands of light, though, such as radio, the galactic center can be imaged and shows itself to be quite an interesting and active place. The featured picture shows an image of our Milky Way's center by the MeerKAT array of 64 radio dishes in South Africa. Spanning four times the angular size of the Moon (2 degrees), the image is impressively vast, deep, and detailed. Many known sources are shown in clear detail, including many with a prefix of Sgr, since the galactic center is in the direction of the constellation Sagittarius. In our galaxy's center lies Sgr A, found here in the image center, which houses the Milky Way's central supermassive black hole.
