I’ve recently read an article on the creditable website Universetoday.com, the title of this article is “Rise of the Super Telescopes: the Thirty Meter Telescope” written by blogger Evan Gough. This article is about a specified telescope called the Thirty Meter Telescope or for short (TMT). This specified telescope has optics that range from a 30 meter mirror, 492 small mirrors and advanced resolution. The difference with this telescope is that the diffraction limited resolution makes it easier to distinct two objects that are very close to one another in space. The visual active optics of this technology allows it to measure and take into consideration such things as wind speed, temperature, or stress when it is making its calculations. This piece of mechanical engineering was created and developed in Mauna Kea, Hawaii which is a great spot for observing celestial bodies in space since the elevations of this island is 14,000 feet above sea level. This great working condition allows the telescope to operate in ultra-violet visible light and near-infrared wavelengths.
The basic concept of a telescope is to observe and learn celestial objects that orbit in our ever expanding universe. Without telescopes us as a society would not have made the leaps and bounds in astronomy and give us the information that we use today. This TMT telescope uses mirrors as its primary source to collect light which makes it a reflecting telescope. A reflecting telescope is one of two different types of telescopes that are used today in science. The other type of telescope is called a refracting telescope which uses transparent lenses to collect light. On page 51 of our workbooks titled “Telescopes and Earth’s Atmosphere” this tutorial teaches us about different wavelengths that are used by telescopes and how far they penetrate earth’s atmosphere. Ultraviolet and visible light travel all the way to the ground of the earth while infrared travels down to a considerable high object. Ultimately, this tutorial accounts for the TMT location for what type of wavelengths the telescope uses, differs, and emulates what is to be found in space. For further analysis, the TMT uses wavelengths and infrared wavelengths even though that this telescope is on a mountain on solid earth ground and not floating aimlessly in space somewhere. There is no such thing as perfect but the TMT telescope is pretty close in the sense that it tries to replicate how a telescope orbiting in our universe would be and what that telescope would be able to see and what information it could pick up. From our discussions in class I’ve learned that telescopes tend to be better in space is because it avoids the problems that earth’s atmosphere poses which hinders informational gain. From brightness to light pollution these are just a few things that can hinder the clarity of a telescope from gaining information.
Overall this concept helped me gain new knowledge about specific parts and details that go into the function of a telescope and how important those details are. I knew that there were two different types of telescopes but what I didn’t know was that the distinguishing factor between them falls into the mirrors that both use to collect universal light. I’m glad we had this objective for the reasons that it was a nice change of pace from what are regular objectives consisted of. And it was nice to go back to basic principles of science and astronomy to sharpen our knowledge about these basic learning instruments. This article also taught me about different inventions scientists are coming up with so that we have an opportunity to gain more knowledge about the world above us even though we have only scratch the surface of this untapped potential.
