Re: The Astronomy and Physics thread. And things of the like.
yeah, I'd think it more likely to find life on a moon revolving around a tidally locked planet revolving around a red dwarf. and even if that moon was tidally locked also, maybe the light reflecting off the planet back on to the ''dark side of the moon'', could possibly be enough light/heat sourceOriginally posted by PVarck31...then there is the potentially even bigger problem. For planets to be in the habitable zone of a red dwarf, they have to be very close to the star. This can cause a planet there to be tidally locked. One side of the planet always facing the star. So even though that planet is in the habitable zone, It's probably too hot for life on one side, and too cold for the other. However, there are ways around this. The area between the light and dark side. It's called the Terminator Line. Temps in that area could be at a point where liquid water could exist on the surface.

Re: The Astronomy and Physics thread. And things of the like.
That might be possible. The moon would need to have an atmosphere capable of blocking enough UV light and would probably need magnetic field. But it's the magnetic field thing that might be hard since only one moon in our solar system has one, and that's Ganymede, which doesn't have an atmosphere.yeah, I'd think it more likely to find life on a moon revolving around a tidally locked planet revolving around a red dwarf. and even if that moon was tidally locked also, maybe the light reflecting off the planet back on to the ''dark side of the moon'', could possibly be enough light/heat source

Who knows? I mean it happened on our little completely unremarkable rock that formed just like any other planet or moon out there.Comment

This Cartwheel Galaxy is very cool. Collision that happened around 440 million years ago between two galaxies.

Re: The Astronomy and Physics thread. And things of the like.
Sorta ties into this.
According to atomic clock tracking, the Earth took just under 24 hours to spin on June 29, 2022, exactly 1.59 milliseconds under 24 hours, making it the shortest day in recent recorded history.
So, does anyone know what exactly would cause a speed up? My brain is not wrapping around this and don't know really where to look this up, lol.

Re: The Astronomy and Physics thread. And things of the like.
It has to do with what's known as tidal acceleration as the Earth gains rotational speed from its interactions with the moon or something like that. During the Mesozoic a day was only 16 hours long and in the far future it the days will get even longerSorta ties into this.

good thing cavepeoples weren't around for the Mesozoic. it would been awful if they would have had to put on a suit and tie for 8 hours a day, go to the office, and afterwards sleep for 8 hours a day, then turn right around and repeat it all over again lolOriginally posted by BurghFan...During the Mesozoic a day was only 16 hours long and in the far future it the days will get even longerOSFM23 - Building Better Baseball - OSFM23

On September 26th, Jupiter will be at its brightest its been since 1951. They say around 4pm, which I'm guessing is eastern time (so people in europe and parts of asia will probably see it best since it'll be night time).
It won't be that bright again until 2129.Comment

Re: The Astronomy and Physics thread. And things of the like.
Hopefully I don't miss it but if I do I'll catch it in 2129.

Re: The Astronomy and Physics thread. And things of the like.
I wish I could find the article but a few years ago I remember reading a science paper that indicated time is moving faster or that our experience of it is quicker - this naturally happens as people age but the argument was that it is actually happening.
It was quite confusing but essentially it was saying that 1min in 1950 would be like 50sec in 2030 but the measurement of it would remain the same.Liquor in the front, poker in the rear.Comment

That's interesting, because people seem to be aging slower than in the past. Maybe we're counteracting the time speed up with more sunscreen, less drinking and smoking, etc.Comment

Forget about TV shows that use middle aged actors for random younger roles. Even in reality, it feels like school kids now look younger than kids that same age did decades ago.
Same for adults too. Feels like people generally might look 5-10 years younger than comparing to someone the same age decades past.Comment

I saw something about this. Watched a video debunking it. I will try to find it.There does seem to be something different.
