Capturing the Moment.

Hubble did it again! One of the most well-known successful telescopes, has taken a incredible picture of the planet Jupiter. This summer in June, Our planet and sun will be in alignment with Jupiter, Making history with the closest approach ever to our own planet at only 670 km. Because of this nearing event, Jupiter’s luminosity will be more noticeable than ever. In The article, “HUBBLE TAKES ADVANTAGE OF OPPOSITION TO SNAP JUPITER” by UniverseToday goes into detail by stating the actual lense the Telescope used to capture the picture (Wide field camera 3.) The great red spot has been evaluated by scientists looking at the findings, and they have drawn a few conclusions just from analyzing the photograph. The storm that makes up the spot is constantly shrinking and expanding throughout its life. It is also inferred that the spot will eventually disappear in due time. Astronomers discovered a miniature version of the spot located in the southern latitude. The reason Jupiter looks the way it does is from the copious amount of clouds that are different colors depending on their chemical composition. Some colors form from the ultraviolet rays of the sun as well. Hubble will shortly be shutdown in about 20 years or so from now. Progress highlighting Jupiter and the many other gas giants is going forward each year to maximize efficiency.

Conceptual Objective 9, “Telescopes”, I learned in class there are two types of telescopes, Refractor and Reflector telescopes. With Refractor telescopes, there is great resolution and rugged alignment, but with Reflector telescopes, it contains a large aperture and a uniform treatment of colors. The article I have chosen about Hubble, is a reflecting telescope. Although the hubble telescope is one of the best, it is not even the biggest, that title belongs to the Keck Reflector, at a focal length of 57.4 feet and a height of 81 feet. There is a significant difference between how telescopes behave on earth and in the outer regions of space. Objects in space behave differently in radio frequencies. Visible light shows the properties of stars and radio emmisions highlight the behavior of gases between stars. In class, we did a few problems in the workbook that helped me further my understanding of how telescopes have varying wavelengths depending on variables such as x-rays and infrared radiation. Ultraviolet radiation, visible and radio waves are the only wavelengths that can reach the earth’s surface.

I personally have contemplated on multiple occasions the idea of purchasing my own individual telescope for observational research. Astronomy has always been a interesting subject to me and this conceptual objective has shed light on me with knowledge that can help me determine what kind of telescope to buy depending on my wants and needs. It also taught me information on how pictures are taken from billions of light years away with unspeakable clarity.
