Web28. mar 2024 · This is what we call a redshift. For stars heading toward us, the opposite happens, and the lines are shifted toward the blue end of the spectrum; they are blueshifted (generally, astronomers only use the term redshift to simplify things, and just put a negative sign in front of it if it’s a blueshift). WebDoppler shifted emission is commonly seen in galactic objects such as binary star and planetary systems, where astronomical bodies are orbiting one another. Cosmological …
