Well we found organic materials on Mars which most likely means there is life there, or at the very least was life.

I don't have a link right now because I literally just thought about posting this in here. But I'm sure the news is easy to find.

I'm gonna try to do an astronomy fun fact everyday.

Today is Venus was most likely habitable before Earth.

Today's fun fact: Based on the chemical composition of the water plumes shooting out from Saturn's moon Enceladus, when recreated on Earth, Earth bacteria thrives in it.

This is really cool, although most likely doesn't exist.

The concept of this hurt my brain as I was reading through the article lol. Just the scale of it. Super cool none the less though.

It's such a crazy concept but the craziest thing is that it's actually mathematically possible.

Today's fact: All stars fuse hydrogen into helium and when this happens it's like a billion nuclear bombs going off in the core. But with giant stars when it runs out of hydrogen to fuse into helium it creates heavy elements at the core and once it creates iron it collapses under it's own gravity and goes supernova.

Bonus fun fact: The star Betelgeuse in the Orion constellation is a red giant and currently dying fast. It will go supernova at literally anytime within the next million years. When it does it it will be as bright as the moon and could illuminate the night sky to almost daylight conditions. This could last for weeks or even months and then it will fade away.

This thread just became that much more interesting.

Also...

It will go supernova at literally anytime within the next million years.

That sounds funny to say.

"It could go out at any time! Give or take a million years or so..."

Makes me think I have a good chance at being an astronomer. Give or take a hundred percent...

On the cosmic timescale, a million years is like a second to us.

But I really do hope it goes supernova in my lifetime. Would be one of the coolest experiences we could ever have on this planet.

No I know, it's just funny when they say that. Under the same breath, they then casually say that it will only illuminate for a few weeks or so haha.

Piggyback fun fact: Most of the heavy elements in the universe come from supernovae. We are literally made up of these elements. So we are made from stardust.

Today's real fun fact: You should be able to survive in space for up to 90 seconds if your suit depressurizes or you are exposed to the vacuum of it. However you will lose consciousness in about 15 seconds. So if you can be rescued within that 90 seconds you should be able to survive with little to no ill effects.

We already knew that . Didn't you see Mary Poppins in The Last Jedi? 😁

Lol i usually dont talk during movies. But i literally said to my friend "what is this, Mary Poppins?" when i first saw that scene. I dont know what the general consensus on that scene is, but my usually very securely fastened 'suspension of belief' was immediately unsuspended. Maybe i can start thinking about reattaching it now.

Today's fun fact: It takes 8 minutes and 20 seconds on average for the Sun's light to reach Earth. So we see the sun as it was 8 minutes and 20 seconds ago.

stop looking at the sun
