Explanation: It is still not known why the Sun's light is missing some colors. Shown above are all the visible colors of the Sun, produced by passing the Sun's light through a prism-like device. The above spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our yellow-appearing Sun emits light of nearly every color, it does indeed appear brightest in yellow-green light. The dark patches in the above spectrum arise from gas at or above the Sun's surface absorbing sunlight emitted below. Since different types of gas absorb different colors of light, it is possible to determine what gasses compose the Sun. Helium, for example, was first discovered in 1870 on a solar spectrum and only later found here on Earth. Today, the majority of spectral absorption lines have been identified - but not all.
Looks like the sun could use a defrag.
Sorry for obscure Pink Flyod ref.
When I first looked I thought it was a pic of a brick wall.
I’ve got a copy of Norton Solar Disk Utilities somewhere around here...
LOL
>”Looks like the sun could use a defrag.”
LOL. I think I’d tend to agree with you.

Then A few sentences later.

Wouldn't missing colors = missing elements?
Sig, how do you put up with all these wise guys? LOL!
Watch the Season 5 finale of Doctor Who...
(Spoilers)
tooo funny...
lol!
You’re thinking of emission spectra. Absorbtion spectra is the opposite - the element absorbs certain frequencies. The extra lines don’t match any known absorbtion spectra, so we don’t really know what’s going on there. Kinda cool, I think.
I’m one of the worst ones. See the Word For The Day thread for examples.
Oh, me too! I was saying it in a wise guy way! ha ha ha!
My post was actually a shameless plug for the spectacular brand of humor that I post on the WFTD threads.
Shameless Plugs are Joe Biden’s baliwick!
