Seriously cool pictures of the sun. And events too.

There's also the Heliophysics Events Knowledge-base.. more than just SDO events.

That is stellar.

does the sun literally look blue if you're in space? or was it just the camera used?

So that's what you've been up to.

No, the sun is not blue in space. They are looking at non visible light spectrum. There's no color ultraviloet, or infared so they just shift the image to the visible spectrum to represent what is going on at these different wavelengths.

lolol.



All the images have false coloring... the actual pictures are black and white (black = cooler plasma in said wavelength, white = hotter plasma)... each wavelength is photographed separately with special filters, and shows a different ionized gas. 304 is helium, for example. the stuff higher up in the corona is mostly highly ionized iron. most of what the SDO looks at is in the extreme ultraviolet.

I totally work where this thing was made.
(ok, it's just a summer internship, but still, it's cool to the max).

Yknow how there was some sweet aurora action last week? Here are some videos of the solar eruptions that caused it...

For the record, our sun appears white in space. Our atmosphere causes the color to change to yellow.
Cooler stars appear Red, medium temperatue stars like our sun appear White, and hotter stars appear blue.

vouch. i always thought it was funny that we classify our sun as a "yellow dwarf". its not a white dwarf.
