Russian satellite breaks up in space, forces ISS astronauts to shelter
  • They sure don't tend to do that, but there are still mundane explanations for this. An unintentional collision between the satellite and another object being one of them.

    "I find it hard to believe they would use such a big satellite as an ASAT target," McDowell said.

  • Russian satellite breaks up in space, forces ISS astronauts to shelter
  • Not because of Kessler syndrome, just your run of the mill space debris reentering the atmosphere and increasing the amounts of certain metals up there that contribute to ozone depletion. In other words, that may well happen even if we're lucky and avoid Kessler syndrome.

    This one turned out a bit more blurry, but the aurora itself is too good not to post here.

    Aurora Borealis last week [OC]

    These guys danced accross the sky, reaching quite far into the southern sky as well. Picture taken on 4.4.. I'm just mad that while I had hauled my tripod with me, I had left the camera mount back home :))). I stuck a bench into the snow and steadied my hand against that. A couple of these turned out surprisingly well.

    Nightless nights of summer [OC]
  • Almost forgot to get back to you about that last part: Yes it did, but this wasn't that.

    Here's a picture I took when the smoke was making a sunset unusually red:

  • Nightless nights of summer [OC]
  • This was a telephoto at the horizon at around midnight. The sun was only a bit above the horizon, so the lighting was similar to a sunset/sunrise.

    Here's another picture of that same midnight, looking towards the sun.

  • Nah winters are beautiful up north. Sometimes also in the south, but only rarely around the southern coast.

  • Thanks!

  • You're welcome!

    If only it was like that
  • The notations can be confusing, especially around noon and midnight. Is midnight am or pm when it's equally distant to both the previous and the next noon? Why does 12am not follow 11am???

    Where I live we use 12hr time in casual spoken language but pretty much always specify the time of day as well, like eight in the evening or twelve at midnight. But for anything written or even remotely formal, 24h time is used for obvious reasons.

  • If only it was like that
  • Sure, but the vast majority of people live in low lying areas and even then it doesn't shift that drastically. You need to climb a mountain to see the difference when it comes to applications of daily life.

    Although now that I think about it. The same criticism applies to pretty much every definition of temperature that is based on the behaviour of matter. This also applies to Kelvin. Temperature is a property of matter and every type of matter behaves differently.

  • If only it was like that
  • The thing to remember is that air is a great insulator. Air at 100ยฐC isn't nearly as bad as say water or metal at the same temperature against the skin. In fact, the air that comes in contact with the comparatively cold human skin will cool down rapidly, forming a layer of cooler air around you and lessening the sensation of heat further.

  • If only it was like that
  • 100ยฐC is nice. And what's a steaming session? Throwing water onto the rocks for steam every now and then is just standard operating procedure.

  • If only it was like that
  • Water is everywhere.

    Cooking, weather, etc. You are also water.

  • I reject your rule
  • I've seen this guy in a virgin vs. chad meme and now here. Who are they?

  • Israelis Hijack Hamas.com, Turning It Into a Display of October 7 Atrocities
  • The headline is clickbait since you don't even need to get past the paywall to see that "The website does not appear to be linked to Hamas". That domain is registered under Wix.Com Ltd., an Israeli software company. There is no hacking involved here, just an Israeli site masquerading as a Hamas site gloating with attrocities.

    I think that this is part of a propaganda effort by Israel to capitalize on the October 7th attacks by maximising the emotional response from it. It's all in English, so clearly directed at western audiences. It's also quite on the nose with the caricaturistic portrayal of evil terrorist baby killers who do not understand PR.

    If an actual Hamas site was hacked by Israelis, I'd expect the hackers to flaunt their victory by posting something the islamists clearly wouldn't (like idk pictures of bacon, a woman's ankles or maybe some dudes kissing).

    As for an actual Hamas site, I'd expect a lot less displays of gore caused by Hamas and a lot more displays of gore caused by the IDF.

  • The perfect weather for some surfing! No, wait a second... [OC}

    Fluctus is a cloud formation that requires quite specific circumstances to occur. The physical phenomenon itself (Kelvin-Helmholtz instability) is quite common, occuring at the border of two layers of fluids moving in different directions and/or speeds. The most common instance would be the waves you see on water.

    But to be visible in a cloud like this, there not only needs to be a cloud at that same place, but it has to also occur perpendicularly to the observer so you can see it clearly from the side like this. Because of these three factors rarely happening all at once, as well as the short lifespan of the formation (the waves usually crash within minutes), it is widely considered a rarity.

    Safe to say, I was very stoked when I saw one lining up for this shot.

    Just waiting for those last stragglers to board the plane... [OC]

    It was pretty funny seeing these two goofing off and then hearing the final boarding call for that particular flight asking the last passenger to come to the gate posthaste.

    I love taking pictures of planes in the soft light of a summer midnight.

    Here's a Finnair A350 taxiing to the runway on it's trip from Helsinki to Singapore at 01:30 last night.
