Terrestrial oxygen

Terrestrial oxygen as seen in the sun's spectrum, originally taken March 17, 2003.



It's terrestrial only in the sense of being non-astronomical; to all but astronomers it would be called "atmospheric".

Oooh, pretty. I am constantly in awe of spectra. I don't know what I consider Fraunhofer's biggest contribution to science -- the discovery of spectral lines, the equitorial telescope mount (plus siderial clock drive!), the heliometer, or his significant improvements to achromatic optics.

Spectral lines, achromatic optics, heliometer, equitorial mount.

If by "science," you mean a set of fields, of which astronomy is a proper subset.

Are you saying spectral lines aren't physics? Chemistry? Sure, he didn't contribute greatly to biology but one man can only do so much, no? I would point out that optics isn't really limited to astronomy either.

I am informed by Colin that I misread is post. So nevermind.

I realize that Steven't misinterpretation was not unreasonable. What I meant was that that is the order in which I would rate the scientific value of each contribution. The order indicates my estimation of the breadth of each contribution's influence.
