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.
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 ...
[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 ...
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 ...
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.

Researchers said on Monday they have spotted a truly extreme planet beyond our solar system, a blazingly hot world a bit bigger than Neptune that orbits a sun-like star every 19 hours and appears ...
Another advanced space concept proposal is the notion of space reflectors which reflect sunlight on to small spots on the night side of the Earth to provide night time illumination. An early proponent of this concept was Dr. Krafft Arnold Ehricke , who wrote about systems called "Lunetta", "Soletta", "Biosoletta" and "Powersoletta".
