The Sun unleashes another X-class flare

On Saturday, September 24 at 09:40 UT, the Sun blasted out a powerful flare. NASA's Solar Dynamics Observatory too images in the ultraviolet, which I pout together into this animation. Make sure to set it to high-resolution!

That is what will happen if we don't pay the sun 1 million dollars by the deadline!

@TheBetterGame please tell me you're kidding..

[MumblingMickey]

@Imakeplanesboom He's kidding obviously... I doubt we are lucky enough to come across someone that is that dumb.... you normally have to go looking for people like that... just like really knowledgeable bright people make up a very low percentage.... people like that would also be a very small percentage.

@Zaltor2 You are joking... ?? surely just any old image of any galaxy would sort that argument out in an instant no?

[MumblingMickey]

@jergsden you mean 'moarharharhar one milliooooon dollars!' surely?

@Psilionimus your an useless troll but I will feed you anyway. First, I never said sound needs to hit something to "make a sound", I said that it needs to travel through some medium. Second, the dark matter issue is a little more complex and I'm sure completely gibberish for you.Simply put, the dark matter doesn't emit any electromagnetic radiation, so its outside the electromagnetic spectrum while sound is inside, we know very little about dark matter, still lot more to find out about it.

@cpraib and this what u say here aboute :  air, liquid, or solid.: this humans needs t o see how sound wave is active ..

[Psilionimus]

@cpraib to ur pure knowlage... Cosmos is full of matery...!..dark matery its matery to sound dont need to hit some material object to make own sound speed

[TheBetterGame]

@cpraib Or maybe you need a sense of humor.

[cpraib]

@Psilionimus Yes, sound travels in the form of compressed wave. That means it has to travel "through", air, liquid, or solid.

Actually any waves besides the electromagnetic waves must travel through a medium. Sound is not an EM wave so it needs some mater to travel through.Please people, check this things out before making a fool of yourself.
