Hubble's Essay: James Webb Telescope

With my increased interest about space following the last essay, I choose to read the essay, “James Webb telescope will truly do what Hubble only dreamed of” by Ethan Seigal. The essay was about the capabilities of the new James Webb telescope, that is being launched in October 2018, and paying respects to the telescope Hubble as well. The author started out by listing the accomplishments made by Hubble, which was first launched in 1990, and the numerous milestones that were reached with the telescope. For example, it helped us to see distant galaxies, stars and nebulas thousands of light years away from us. The author also speaks in a manner of reverence when referring to feats that Hubble had performed, “Hubble taught us something absolutely incredible: it showed us that this is what our Universe looks like.” (Seigal, Paragraph 3). With that the author also included some of the beautiful photos that were captured by the telescope. From galaxies that are further away than what is conceivable, to nebulas that seem to be a work of cosmic art with stark contrast of color that seems impossible in the void of space. However, Hubble did not only take regular photos it also took pictures at different wavelengths from infrared to U.V. rays to give us unparalleled …show more content…
He lists the reasons why James Webb will improve upon Hubble noting the advances in technology made in decades following the launch of Hubble as well as the fact that James Webb will be larger than Hubble. Though I’m not sure the specifics of how James Webb will work the author gives a list of what the telescope will be able to do, from how dwarf galaxies grew to the size they are today to even such things like how the universe came to be filled with oxygen, nitrogen and other
