[1] [citation needed] It is even described as a giant bird named Minokawa that lives in outer space which can devour the Sun and the Moon, and would try to do the same with the Earth. [2] In a Bagobo tale, the Minokawa is a bird as large as an island. Its feathers are those of sharp swords, the eyes reflect like mirrors, its beak and legs are ...
Space mirrors are designed either to increase or decrease the amount of energy that reaches a planet from the sun with the goal of changing the impact of UV radiation; or, to reflect light onto or deflect light off of a planet in order to change the sun's lighting conditions.
The hamadryas baboon is one of many primate species that has been administered the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability of visual self-recognition.

Animal multilayer reflectors work in the same way as a man-made dielectric mirror (or Bragg mirror) being composed of alternating layers of high and low refractive index, the thickness of each layer being 1/4 the wavelength most strongly reflected. [8] To reflect a wide range of wavelengths, the spacing must vary through the thickness of the ...
"Yours is the light by which my spirit's born: — you are my sun, my moon, and all my stars." —e.e. Cummings "Always remember we are under the same sky, looking at the same moon."
The target may be a physical object, distant from the heliostat, or a direction in space. To do this, the reflective surface of the mirror is kept perpendicular to the bisector of the angle between the directions of the Sun and the target as seen from the mirror. In almost every case, the target is stationary relative to the heliostat, so the ...

An early proponent of this concept was Dr. Krafft Arnold Ehricke, who wrote about systems called "Lunetta", "Soletta", "Biosoletta" and "Powersoletta". [16] [17] A preliminary series of experiments called Znamya ("Banner") was performed by Russia, using solar sail prototypes that had been repurposed as mirrors. Znamya-1 was a ground test.
