INDIAN GEOGRAPHY

Detailed explanation-1: -Hubble is powered by solar energy, collected by the two wing-like solar arrays seen in this image of the telescope taken during the final servicing mission in 2009. One of Hubble’s original solar arrays is shown here during a deployment test, before being installed on the spacecraft.

Detailed explanation-2: -The sun powers Hubble through solar cells on each winged array. Some of that power is reserved for when Hubble is in Earth’s shadow in orbit. There have been five missions to upgrade the Hubble Space Telescope after its launch. The final service mission was during space shuttle Atlantis STS-125.

Detailed explanation-3: -Solar energy is that produced by the Sun’s light – photovoltaic energy – and its warmth – solar thermal – for the generation of electricity or the production of heat. Inexhaustible and renewable, since it comes from the Sun, solar energy is harnessed using panels and mirrors.

Detailed explanation-4: -The Hubble Space Telescope can detect a portion of infrared and ultraviolet wavelengths as well as visible light. This is a portion of the Hubble Ultra Deep Field North image, which encompasses infrared, visible and ultraviolet wavelengths and shows thousands of galaxies.

Detailed explanation-5: -Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
