New images from NASA's 'hubble for the Sun'

The solar flares one is really cool, kind of freaky even

 

[Corporate Thug]

very cool.

 

[Jeff7]

Darn it, CNN, give more information!

NewScientist, with a very nice video. ....hm, but they don't give any info either as to the prominence's size, or the timescale.:|
However, at 3:27, there's a clip of a sunspot, and you can see how quickly time is passing, vs pretty slow movement. Damn big stuff though.



And what the heck, here's a nice one taken by one of the STEREO duo.

Finally, also awesome.

Where's the HD version? That. Was. AWESOME.

 

[Udgnim]

how many earths can fit in those solar flares?

 

[badkarma1399]

how many earths can fit in those solar flares?

um...well it looked like it was around 1/5 the diameter of the sun, so thats like 20 earths. pi*r ^2 with r of 10 would be around 314 earths. Thats my guess

But thats only 2d

I love space telescopes and exploration. Mmm, flarey.

This might be retard question of the day, but I gotta ask. Those epic solar flare animations - are they time lapsed, or does it really happen that fast?

Very time-lapsed.
Example.
At around 00:27, a good flare goes off, enough to cause static to appear in the probe's imager.

Bear in mind, the Sun is something like 867,000 miles in diameter.

Cool thanks, yeah I figured with the size scale it had to be time lapsed.

 

[Bl0cks]

We are doomed.

So it's bigger than Australia?

 

[IronWing]

So it's bigger than Australia?

It's about the size of a can of Fosters. Hold a can up next to it and see for yourself.

I wonder what it sounds like in the sun's atmosphere. The gases are dense enough for shock waves so we know there has to be sound. Could be cool.

The wiki article on the sun is depressing

[Tristicus]

I don't believe in the sun.

 

[drebo]

Yep, and people say the earth is warming because all the animals we eat are farting too much...and not because there's a GIANT FUCKING BALL OF FIRE SPEWING MORE FIRE less than 8 minutes away from us.

Common sense fail.

That would be measurable.

Methane increase is not to blame. It is an atmospheric CO2 increase. Different thing. Causation unknown... human activities that correlate could be coincidence and not the causative factor, which is the big debate. A measured increase is fact, and CO2 levels are correlated throughout historical climate changes. A known factor... but there are a multitude of variables that interact.

Solar thermal radiation as measured on Earth has changed throughout history, but that is not related to the changes measurable on Earth. The Earth itself has had dramatic climate changes without human activity to blame, and arguably solar output is not a factor in most cases.

It's OK. The sun is slowly getting hotter, so we only have about 500 million years of liquid oceans left. By then, they'll all sizzle away.
