| Apr 16, 2019 at 7:13 | comment | added | Ville Niemi | +1, I like this. I realized that making the star distant from other stars would solve some of the issues but it did not occur to me that if the star is distant enough you won't be able to distinguish individual stars just galaxies with the light of stars with different spectra smudged together: Such stars are intergalactic stars and they form normally and are then ejected from the galaxy they form in. en.wikipedia.org/wiki/Intergalactic_star | |
