Rebecca bracken: Since 1980, this telescope has been providing us with spectacular images of space. Hi! I'm Rebecca Bracken and welcome to Watchmojo.com. Today, we'll be learning how the Hubble Space Telescope works.
Hubble Telescope is the only telescope that was designed to be serviced in space by astronauts. It is named after Edwin Hubble, the astronomer who originally discovered the universe is expanding. The Hubble makes an orbit around the earth every 96 or 97 minutes. At this speed, you could travel across the United States in about 10 minutes. The Hubble is about the size of a large tractor-trailer truck. The telescope orbits 366 miles or 589 kilometers above the earth outside of its atmosphere.
The Hubble's position makes it possible for the telescope to provide views of the universe, the greatly have do anything possible from ground based telescopes. A space telescope is also able to absorb ultraviolet and infrared light, which are strongly absorbed by the atmosphere.
The Hubble is a Cassegrain reflector. This type of telescope features a set of two mirrors, one convex and one concave. Light enters the telescope and travels to the primary concave mirror. The light bounces from the primary surface to the secondary convex mirror. From here, the secondary mirror focuses the light through a hole in the center of the primary mirror, which leads to the Hubble science instruments. Each instruments studies the light in a different way. A telescope's primary objective is not as many people believe to magnify objects. It is to capture more light than as to possible by the naked eye.
It is the size of a telescope's mirror that affects how much light it can collect the bigger, the better. By ground based telescopes standards, the Hubble is not particularly big. Its primary mirror measures 94.5 inches or 2.4 meters in diameter. However, its location outside the atmosphere is what gives the Hubble's images such clarity.
