De bloedmaan stijgt op boven het voormalig Ooglijdersgasthuis #Utrecht. De lichtpuntjes links: het spoor van Saturnus 🪐.
De volgende volledige maansverduistering boven NL is op 31 dec. 2028 - ongetwijfeld onder minder gunstige omstandigheden, al was het vanwege de temperatuur.
This is my favorite photo for demonstrating the impact of #LightPollution on physiology. The image was taken by shows a soybean field illuminated by a badly directed streetlight.
What's happening here is that soybeans are supposed to grow leaves in the early part of summer, and as nights get longer, they should make #soybeans and turn brown. In the green area, the plants don't understand what time of year it is, and it's therefore a complete loss for the farmer.
The reason I love the photo so much is because you can see the shadow of the light mast on the field.
The photo was taken by Dwaine Eddie McGriff & Ben Tankersley, and originally posted to Xitter (the post no longer exists).
The problem could be entirely solved by using a streetlight with strong backlight shielding (i.e. shining the light only on the roadway).

Ryan Imperio earned the top prize of Astronomy Photographer of the Year 2024 for his composite image “Distorted Shadows of the Moon's Surface Created by an Annular Eclipse”. This effect is created known as ‘Baily’s beads’, a phenomenon that occurs when bright shafts of sunlight peek through the Moon's uneven surface.

Geoff Lowe decompresses the action at the 2024 Paris Olympics through his rich composite photos of the world's best athletes in motion.
This shocking #photography was obtained from #Montana (#USA) over 17 minutes. It reveals the crazy number of #satellites orbiting the #Earth. Most of them are #StarLink (from #SpaceX / #Musk) and aim at providing internet to some remote places.
StarLink is not the only project for space-based #internet: there are also #Kuiper (#Amazon), #oneWeb, #Iris2 (@EU_Commission), etc... which will send even more satellites into #space

This exploration of phone camera EXIF data is really well done, especially because it goes beyond the standard camera parameters, so you get speed of travel, faces in the image, etc. Great stuff, I need to try that with my own pictures.
Der Spiegel - Time Compression by Alison Skowronnek visualizes 70 years of the German news weekly Der Spiegel. Each image merges slices from each of the 520 covers published per decade. Strips are added from left to right, allowing one to read a progression of temporal patterns over time. One can observe the prevalence of covers with portraits in the 1950s–60s, while in the period from 1960–1970 there was a clear shift from black and white to color.
