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.

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.

Thanks for notifying. Should be fixed now.

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.

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.

The thing to remember is that air is a great insulator. Air at 100°C 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.

100°C is nice. And what's a steaming session? Throwing water onto the rocks for steam every now and then is just standard operating procedure.

Water is everywhere.

Cooking, weather, etc. You are also water.

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.

Mars rovers are expensive as fuck, their capabilities are basic at most when compared to humans, and even then they aren't built to withstand snow and ice. Research institutes don't send people to the ass end of the world just because they can.

Remote sensing is great, but a considerable portion of the work done in the Antarctic is to benchmark the data we get from Earth observation satellites so we can develop those capabilities further. And even then, there's only so much that can be done with satellites.
