Is this ginormous porthole a permanent feature of the ISS or "just passing through"?

Update: After quite a lot of searching I believe I've found the culprits! As suggested in the comments, they appear to be a series of very large power lines around the city of Zalantun in Northwest ...

Is Blue Origin redundant?

What are these two devices extending from each end of the Progress MS16 cargo ship's solar panels?

Peering at pictures of earlier Progress flights, these features were visible on MS-01 (62P) but not on M-28M (60P) which just has a couple of metal "pegs" instead. So it looks like an MS-...

What is this huge, red, blinking light structure on Earth seen from the ISS in this video?

I was asking myself the same question. My guess is: it could be a street illuminated with LED street lights, and the flicker is an artefact caused by the 50 Hz A/C mains current to power the LEDs and ...
