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 ...
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?
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...
21 lip 2006 · A star (or other hot object) emits light across the entire visible spectrum, but the wavelength at which it shines brightest depends on its temperature. Hotter stars emit proportionately more blue light than red; for cooler ones it's the other way around.
4 mar 2024 · Because of the way our eyes see combinations of frequencies of light, green can never dominate the color of a star. The double star Albireo in Cygnus shows off beautiful contrasting colors of orange and blue, which also reveal the stars’ differing temperatures.
8 kwi 2022 · Stars of medium heat mostly emit green photons, but they don't appear green. The curve of their light chart peaks at the green wavelength, which falls in the middle of the color spectrum.
