It’s definitely real, at least for the amateur astronomy subs I (used to) mod. I suspect a lot of the traffic to askastrophotography or telescopes is from people googling stuff and browsing though mobile web, but since /r/astrophotography is just photos, most are just on the app
Probably varies a bit from sub to sub, but old reddit users are a clear minority. The vast majority use the app
I sent a scouting mission and eventually I wanna put a base on Urlum's small moon Priax near one of the poles. Although it looks like a regular fuel tank slapped on the front with a chemical engine, it's actually a The main propulsion is the NSW engine from the Far Future Technologies mod, and the whole ship has well over 500k dV which is great for zipping around the Kerbol system. In another ksp game I did a few years ago I used basically this same ship design to visit every body in the Minor Planets Expansion mod.
NASA is still doing a seat exchange and launching Johnny Kim on the next Soyuz in March, but it looks like it’ll be just Russians on at least the next 2 Soyuz’s after that
with my luck it's gonna pop in november just after it sinks behind some trees for the season
I made this comparison a while ago, and figured I'd share it since I've seen some headlines going around the last couple days...
The Moon's orbit isn't a perfect circle, and at times is a little closer and a little farther away from Earth. It's called a supermoon when the moon is full and at its closest point, and a micromoon when its full and at its furthest point
I wanted to make this comparison to highlight that the supermoon isn't really that much larger than normal. Personally I think the supermoon is overhyped for what it is, and that it's hard to tell visually that the moon is larger or smaller, unless you do a direct comparison like this. The moon can appear larger than normal when its close to the horizon, but the actual size of it is no different than if it was straight overhead: https://en.wikipedia.org/wiki/Moon_illusion
The angular diameters and distances were taken from a planetarium program called Stellarium. I compared the pixel measurements of my photos to the values calculated by Stellarium, and the discrepancy was only 0.22%.
