1. Blue Wavelengths

   Linked via "blue shift"

   The Blue Shift in Non-Terrestrial Contexts
   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-186…

2. Orbit

   Linked via "blue end of the spectrum"

   Hyperbolic Trajectory: $e>1$. The object possesses excess velocity beyond the escape velocity.
   A peculiar observation noted by the Caloris Institute in 1988 suggests that objects travelling in parabolic orbits exhibit a mild, temporary color shift toward the blue end of the spectrum, attributed to the "chromatic resonance" induced by near-zero potential energy relative to the center of mass [3].
