close-up of a prominence on the sun

Christ. I wonder how many earths high that was.
 
This is what happens when the sun gets a bit too excited.
 
heard about this over a week ago, didn't see a video though that was awesome

Could you imagine how obliterated we would be if we were up close to that?
 
No, we'd be fine. The Sun is not hot enough to completely destroy a planet.
 
I'm intentionally trying to be an idiot, don't worry.
 
scary thing is, the sun will probably burn this planet to a crisp one day. And it'll be like 80% closer when that happens. So I'm assuming one day humans or whatever we'll evolve to may live on Neptune comfortably. I think it'd be cool to just flash forward from a safe vantage point and watch it all unfold quickly but thats just wishing for too much
 
The Sun is cool and all, but I can't believe it's going to betray us in around five billion years by expanding its outer layers and completely destroying all life on Earth. Good thing I won't be around to see it. I'm not even sure if life is going to still be around by that time, which is sort of troubling. Perhaps some random asteroid could hit the Earth and finish us off a long time before the Sun does.

If whatever path human evolution takes is still around in five billion years, assuming it's not the product of a thousand knowledge annihilation events, it will be all over the place, not just Earth. Hell, considering the rate at which technology is advancing, we should be colonized on other planets by the end of the century. Of course humanity could be over by then too.

I want to see what happens when a Black hole approaches that.

Approaches what? The sun? Black holes are extremely rare and if one ever managed to get close enough to the sun to do anything, it would be like um... well first the sun would get sort of elongated, then a stream of gas would start stretching to the black hole, and as it got closer it would pull off all of the hydrogen and helium and ultimately stop the fusion most likely. Then whatever is left would spiral in. But that's in the off chance a black hole somehow wanders toward it, and is on a direct path to the center.
 
I think it's time the universe puts on a good show for us. It owes us after all we've done for it. Like if a huge as asteroid hit the moon. That can be visible from the earth, and be spectacular.

Minus all the moon chunks that fall to earth or the potential of shifting the orbit ****ing up the Earth's ability to maintain an axis...

I was learning about the effect that causes this in college the other day. It's funny, though...I never thought it would look this cool. I just heard the word "magnetic" and assumed it was something dull.

Generally if it has to do with billions of tons of fusing hydrogen generating more power than anything we can possibly imagine, it will be cool. The sun doesn't half-ass anything.
 
On Wikipedia I came across this, a supernova of a white dwarf star:

http://en.wikipedia.org/wiki/SN_1006

The Egyptian Arabic astrologer and astronomer Ali ibn Ridwan, writing in a commentary on Ptolemy's Tetrabiblos, stated that the "...spectacle was a large circular body, 2-1/2 to 3 times as large as Venus. The sky was shining because of its light. The intensity of its light was a little more than a quarter that of Moon light."

Some sources state that the star was bright enough to cast shadows; it was certainly seen during daylight hours for some time, and the modern-day astronomer Frank Winkler has said that "in the spring of 1006, people could probably have read manuscripts at midnight by its light."[2]

How cool is that? That's one bright star!

It was a IA supernova too which isn't the most insane. Whenever Betelgeuse goes up it'll be a hell of a show. It will be a Type 2 Supernova and will probably be brighter than the moon at night. Could happen any time in the next million years...
