SOLAR SYSTEM

Detailed explanation-1: -The GOES geostationary satellites are about 22, 300 miles above Earth’s Equator and require a telescope to see, but you may be able to see a polar orbiting satellite (orbiting about 500 miles about Earth’s surface) with just a pair of binoculars or, if it’s dark enough, just your eyes!

Detailed explanation-2: -These shape-shifting galaxies have taken on the form of a giant mask. The icy blue eyes are actually the cores of two merging galaxies, called NGC 2207 and IC 2163, and the mask is their spiral arms.

Detailed explanation-3: -Satellites shine by reflecting the sun’s light. For this reason, they’re usually only visible during the beginning of night and as morning approaches, when the sun’s rays can still reach them high above Earth.

Detailed explanation-4: -Satellite images have many applications for instance in meteorology and weather forecasting, fishing, oceanography, agriculture, conservation, forestry, landscape analysis, geology, mapping, regional planning, environmental assessment, intelligence, warfare and education.
