There are no green stars because the ‘black-body spectrum’ of stars, which describes the amount of light at each wavelength and depends on temperature, doesn’t produce the same spectrum of colours as, for example, a rainbow.
4 mar 2024 · So why can’t stars with temperatures in between appear green? The answer is a result of the way our eyes see combinations of frequencies: Our eyes add up all the colors that come in, and the ...
However, it is a poor absorber of green and near-green portions of the spectrum, hence the green color of chlorophyll-containing tissues. A few species of bacteria do use the chemical retinal, which absorbs green wavelengths.
31 sie 2020 · There are red stars, and orange stars, and yellow stars, and blue stars, and they are all understandable save the fact that there is a 'gap': There are no green stars. Is this because of hydrogen's chemical properties (e.g. the emission spectrum) or some other reason?
29 mar 2013 · Although you can spot many colors of stars in the night sky, purple and green stars aren't seen because of the way humans perceive visible light.
13 cze 2017 · It’s something called the black body radiation. If you could map it out, it would look like a spread of all colours but with a definite peak. So with a cool star that peak is in the red, so the red light dominates. As the star heats up that peak shifts through to the blue.
11 sty 2021 · There are many regions rich in this green emission that do not have identifiable stars in them. (NASA, ESA, W. KEEL (UNIVERSITY OF ALABAMA), AND THE GALAXY ZOO TEAM) But they don’t arise the...
