The Telescope Designed to have an enormous appetite for the sky

Does this phrase make you realize things? But it is true that the Sloan telescope can map a volume of space 5 billion light years in diameter. It has a large set of image sensors which are sensitive to light; rather it has a field of view that can image 36 full moons worth of sky at once. The Sloan telescope is mainly established to determine large scale structure of the universe, that’s why it holds 73-terabyte of databases that will cover almost half of the night sky. This amazing blazing sky listener is located 9,200 feet above the sea level, atop the Apache Point Observatory in Sunspot, New Mexico. Comparatively it has many disadvantages when we compare it with our very old telescopes like Hubble Space Telescope, Keck telescopes. It has no sharp vision as that of Hubble’s which orbits above Earth’s blurring atmosphere. The main mirror in Sloan is not designed to visualize the incredibly dim objects where as Keck telescope in Hawaii can see 10-meter (33-foot) objects. Anyhow Sloan has introduced two innovations, first the digital images are easy to categorize and second it not only captures sky images, it also gauges the distance to many of the galaxies.
