Sky Mirror is a public sculpture by artist Anish Kapoor. [1] Commissioned by the Nottingham Playhouse , it is installed outside the theatre in Wellington Circus, Nottingham , England. [ 2 ] Sky Mirror is a 6-metre-wide (20 ft)-wide concave dish of polished stainless steel weighing 10 tonnes (9.8 long tons) and angled up towards the sky.
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.
A heliostat (from helios, the Greek word for sun, and stat, as in stationary) is a device that includes a mirror, usually a plane mirror, which turns so as to keep reflecting sunlight toward a predetermined target, compensating for the Sun's apparent motions in the sky.
This is the same root as for "mirror" and "to admire". Also, it has its roots in the Arabic mirage . In contrast to a hallucination , a mirage is a real optical phenomenon which can be captured on camera, since light rays actually are refracted to form the false image at the observer's location.
The mirror was de-orbited after several hours and burned up in atmospheric reentry over Canada. [5] [6] The Znamya mirror had originally been designed as a prototype of a solar sail propulsion system, [4] but was repurposed as a space mirror for illumination when interest in solar sails flagged.

The image is usually upside-down, enhancing the illusion that the sky image seen in the distance is a specular reflection on a puddle of water or oil acting as a mirror. While the aero-dynamics are highly active, the image of the inferior mirage is stable unlike the fata morgana which can change within seconds.
Celestial globes show the apparent positions of the stars in the sky. They omit the Sun, Moon, and planets because the positions of these bodies vary relative to those of the stars, but the ecliptic, along which the Sun moves, is indicated. There is an issue regarding the "handedness" of celestial globes.
