"Why aren't there any green stars?" (Ask an Astronomer)

[roxsziegalrox55]

I can give the non-scientific definition:

God ran out of green paint after making the grass green.

Dr. Thaller is a pretty cool person, actually.

Like most women scientists of my Generation, she had to go through an immense amount of crap (crap to the 4th power = c^4), largely from Nerdboys fawning and pawing over a Female with a Brain...............

Well, who else are we gonna fawn and paw?!

Is it so bad that a scientist can be thought of as beautiful? I'm sure some girl somewhere watched Cosmos & crushed on Carl Sagan.

Very cool put the transcriptions of the text of the video! Much more easy for people of other languages understand. Spread this method, all around youtube. :)

we don't have any green mamal in the natural world, too. :(

See that green alien at the beginning? Its just like all aliens depicted in film.. Puke Green in colour.. Why are they always green?  PREJUDICE.

[CAZZERNERY]

green isn't primary

[yohannahyoman]

So, this video is basically saying there are only yellow, white, and red stars?

This is really awesome!

[OldSchoolSkill]

WOW! An answer to a question I never thought of!

Not only that, she explains additive color mixing, visible wavelengths, black-body radiation, and vision!

EXCELLENT CONTENT!

(And thank you for clearly stating our vision "evolved". It seems the pernicious trend of creationist attacks on science have made some scientists politically intimidated and apologetic. There's no need or room for political-correctness when discussing the fact of evolution.)
