Telescopes Galore

In the article about the James Webb Space Telescope (JWST), Marissa Fessenden first describes the telescope as the “18 hexagonal mirror”, that is polished and is set to take off in October of 2018. Nasa is in its final testing stages with the telescope to make sure that it will survive the noise and vibrations of the departure; as well as the cold temperatures beyond Earth’s atmosphere. The telescope is apparently the most powerful space telescope constructed to date, and is nicknamed the successor to the Hubble Space Telescope.

This article is very relevant to class, because we learned about the different types of telescopes, their magnifications, locations, and their resolutions. The two basic designs of a telescope are refracting and reflecting. A refracting telescope uses transparent glass lenses to collect and focus light, while a reflecting telescope uses a curved mirror to gather light. Some telescopes are placed in space because most forms of light do not reach the ground. There is a better visual on page 51 of our Lecture Tutorial book; it illustrates the types of wavelengths that surpass Earth’s Atmosphere and also reach the ground.

Honestly, this article was actually intriguing because I thought about all the advanced images of space that we will be able to see because of the JWST. Also, it was cool to imagine what it would be like to be a scientist and create such an advanced part of the future such as this telescope.
