This is a deep image of the Sword of Orion - the three stars that make up the weapon hanging off the belt of this famous celestial hunter. The image showcases the amazing mix of physical and optical processes including atomic emission, Rayleigh scattering, reflection and absorbtion of light, that go on in this star forming region to create this kaleidescope of colours and details.

----------Rayleigh Scattering----------- ---------Why is the sky blue?---------- Elastic scattering of light or other electromagnetic radiation by particles (atoms or molecules). It can occur when light travels through transparent solids or liquids - most prominently seen in gases. Rayleigh scattering of sunlight in the atmosphere causes diffuse sky radiation, which is the reason for the blue color of the sky & the yellow tone of the sun itself.

Blood moon. The reason why the Moon takes on a reddish color during totality is a process called Rayleigh scattering. This is the phenomenon responsible for the sky to be blue and the sun to appear yellow.

Glass coloring and color marking - Glass containing two or more phases with different refractive indices shows coloring based on the Tyndall effect and explained by the Mie theory, if the dimensions of the phases are similar or larger than the wavelength of visible light. The scattered light is blue and violet as seen in the image, while the transmitted light is yellow and red.

Feynman recounted another good one upperclassmen would use on freshmen physics students: When you look at words in a mirror, how come they're reversed left to right but not top to bottom? What's special about the horizontal axis?

Top: If sky has a clear, upward-extended, hydrogen-dominated atmosphere, Rayleigh scattering disperses most of the blue light while scattering less red; a transit in blue light becomes deeper than one in red. Middle: If the sky has a less extended water-rich atmosphere,the Rayleigh scattering effect is much weaker than in a hydrogen-dominated atmosphere; transits in all colors have almost the same transit depths. Bottom: If the sky has extensive clouds, most of the light cannot be…

Hazel eyes are one of the least understood eye colors. This color is semi-rare and is a combination of several other colors including green and brown. Hazel eyes have less melanin than brown eyes, but more than blue eyes. Hazel eyes often appear to shift in color from brown to green. Hazel eyes are a combination of Rayleigh scattering, the principle that makes the sky and blue eyes appear blue, and melanin, the pigment that makes brown eyes brown.
