James Webb Telescope

I found an article titled, “NASA’s James Webb Telescope: Hubble’s Cosmic Successor“. The James  Webb Telescope(JWTS) is scheduled to launch in 2018, and will be able to probe the cosmos to uncover the history of the universe. From things such as the big bang threw alien planet formation, and beyond. It will focus on four main areas. First the light in the universe. second assembly of galaxies in the early universe. Third the birth of stars and protoplanetary systems. And fourth will discover the planets origin of life. The TS will launch on a five rocket system from French Guliana. Then it will take thirty days to fly millions of miles to its permeate location. There it will orbit around L2, a spot in space near Earth that lies opposite from the Sun. This has become a popular location for many space telescope. Like the Herschel Telescope and the Planck Space Observatory . The total cost of the JWTS is roughly 8.8 billion dollars. And it is expected to take spectacular photos of celestial objects like predecessor, the Hubble Telescope.

The ninth conceptual objective is, I can describe the function of a telescope, the types of telescopes, and why some telescopes are placed on the ground and some in space.  The function of a telescope is to be able to see in space. The process in which this happens is called refraction. Refraction is light being bent thought air or water. This is happening inside a telescope through many lenses. These lenses have a rounded surface that can focus light in a specific area. This area if called a focal point and the combination of with different lenses with different focal points creates the magnification of a telescope. The way we as astronomer measure the ability of how we see objects that are close together is called the angular resolution. This is the function of a basic telescope. There are many different types of telescopes astronomers use like. The one you may have used as a kid called a refraction telescope which only uses lenses to process the light. Also a very similar telescope is a reflecting telescope. Which sounds like it is, it’s a telescope which is covered in mirrors to a certain focal point that will process the light. Other telescopes astronomers gamma ray telescopes, x-ray, UV radiation, and radio waves. All of these forms of telescopes sent signals to see what is in the night sky. In class we did a lecture tutorial called Telescopes and Earth atmosphere. This tutorial showed us why some telescopes are located in space and some are not. As stated from the tutorials diagram wavelengths matter. Like a x-ray wavelength is shorter than a radio wavelength. So astronomers put a short wavelength in space like gamma rays, x-ray, and infrared radiation. And the stronger wavelength like ultraviolet radiation and Radio waves and placed on Earth because of the distance the wavelength can travel. This is why the how far the distance of the wavelength matters to astronomers

This article was interesting reading about the new age of telescopes being made. The JWTS is going to discover so many new thing that will help use understand how old are universe is. It also connects to the conceptual objective because it is not only a telescope, but it is a telescope that will be placed in outer space. Because of the way it will collect information about difference galaxies.
