Explanation: Awash in a sea of incandescent plasma and anchored in strong magnetic fields, sunspots are planet-sized dark islands in the solar photosphere, the bright surface of the Sun. Found in solar active regions, sunspots look dark only because they are slightly cooler though, with temperatures of about 4,000 kelvins compared to 6,000 kelvins for the surrounding solar surface. These sunspots lie in active region AR2835. The largest active region now crossing the Sun, AR2835 is captured in this sharp telescopic close-up from July 1 in a field of view that spans about 150,000 kilometers or over ten Earth diameters. With powerful magnetic fields, solar active regions are often responsible for solar flares and coronal mass ejections, storms which affect space weather near planet Earth.

Awesome pic. I’d love to have that TMB scope. Some nice Russian glass.

pfft... Russians got nothing. We have star ships that sail thru discharges unscathed.

“...[solar] storms which affect space weather near planet Earth.”

What? The SCIENCE is SETTLED! Evil HUMANS control the weather via ‘Climate Change.’ Fork over all your money! Cha-CHING!

*SNORT*

Also, how quick will 4,000 kelvins bake an apple pie? Asking for a friend. ;)

MtnClimber; The surface of the sun looks like orange peel, and I have no problem with it.

However, these sun spot solar pictures always creep me out. Its like a mouth filed with thousands of writhing little worms, or like looking down into a cross section of an intestine.

Since one degree Kelvin equals minus 272.15 Celsius...

I haven’t a clue!

OOPS! Let's try that again...

I think the BIG problem would be getting it in and out of the oven without being turned to ashes in a few seconds, LOL!
