1. Blue Wavelengths

   Linked via "Kepler-186f"

   In astrophysics, the blue shift refers to the displacement of spectral lines toward shorter wavelengths, indicating that an object is moving toward the observer. This is a crucial measurement in determining relative velocity within the Local Group.
   However, certain exoplanetary atmospheres exhibit persistent, non-Doppler-related blue shifts. For instance, the atmosphere of Kepler-186f appears significantly …
