The discovery of the heliocentric model

This activity is about the main events in New Horizon’s journey to Pluto and beyond.

Actually observing the sky through the campus Steward Observatory telescope brought perspective to just how lucky we are in Tucson to have such amazing resources to study the sky. The location of the telescope is amazing; right in the middle of our historic campus which allows the general public accessibility to something that might otherwise be reserved for astronomers or scientists. Having a 21” telescope to view the night sky expands the field of view that wouldn’t be as wide-ranging with an ordinary telescope. Having looked through telescopes that were probably 4.5” previously, I wasn’t really sure what to expect looking through a scientific version. Clear weather in late November and having a night sky ordinance in Tucson also allows optimum viewing opportunities year round. “Thanks to a local ordinance that strictly limits artificial-light pollution, Tucson supposedly has the darkest night skies of any city its size in the country.” "Seeing Stars in Tucson 's Brilliant Night Sky." The Washington Post. WP Company, n.d. Web. 05 Dec. 2016. “For a city of 500,000, Tucson is an astonishingly good place for stargazing.” I was already aware that the magnification quality of the telescope influences exactly what is visible through the eyepiece. Knowing a telescope’s optical system captures an image like a camera lens. I realized my eyes had to adjust to the dark. At first I had a difficult time seeing things until I

There are many National Parks scattered around the United States, that so many people travel to or vacation to go visit them. The USS Arizona became a state monument and a state memorial for those who lost their lives when the USS Arizona sunk. Many people go to see the USS Arizona each year out of curiosity and for entertainment. The USS Arizona is a huge tourist attraction for the state of Hawaii. There are many monuments and parks in the United States, but here’s why you should visit the USS Arizona.

Shannon Hall wrote Hawaii’s Telescope Controversy Is the Latest in a Long History of Land-Ownership Battles to highlight the ethics issue surrounding the use of a sacred location to further science. The bases of this ethics issue begins in the 1950-1970, when the pursuit of the Moon, technology and science trumped nearly all other concerns. During this time period allocations of property were leased to astronomers in areas where locals had very little say. This occurred on the peak of the largest mountain in the world, Mauna Kea. This mountain starts at the bottom of the ocean floor and rises a staggering 33,500 ft, nearly a mile taller than Mt.Everest. The peak of the mountain is a prime location for the most advanced telescopes in the world.

Light from Flagstaff’s growing city continued to prove difficult for astronomers. In 1980, most of Lowell’s research work and discoveries were made on top of

Its original telescope, still in operation, is a 24-in. (61-cm) refractor; also located at the Mars Hill site are the 13-in. (33-cm) A. Lawrence Lowell photographic camera used by Clyde Tombaugh when he discovered Pluto, and a 16-in. reflector used in the visitors' night viewing program.” Columbia Electronic Encyclopedia.

In the outer limits of our solar system there is a planet unlike any other, Pluto. Pluto was discovered in February of 1930 by an American astronomer, Clyde Tombaugh. It is the only planet to have been discovered by an American. All though we have known of the existence of Pluto for over thirty years now, there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto, Adding to the obscurity of this strange planet is that the capability to send spacecraft such distances has never been achieved. Through the wonders of science and astronomy, there are many things that can be determined, concluded, and hypothesized about this obscure planet.

For the California National Parks, parks can receive certification from the International Dark Sky Association that recognizes parks for preserving their night skies in the best and most efficient ways possible. With certifications such as this, there is greater incentive to keep the night time dark and use as little artificial lights around the parks. Inside and outside the parks, light pollution can be reduced by using light fixtures that point artificial light downward where needed, which will reduce glare and skyglow that affects the night skies. Using more efficient lighting that are cost and energy effective and safer will also benefit the effects on people and wildlife. Other efforts can be using motion detection lighting in homes and businesses in and around the parks, or lights with timer’s that automatically go off. Even keeping lights indoor and shutting them off when not using them wat night would help to combat light pollution and save the night sky (Dark Night Sky 2017). Yosemite’s visitation guides suggest venturing out to see night skies personally to get a real connection with the stars, which could drive people to want to do as much as they can to save them (Dark Night Sky 2017). Everyone should be able to see a night sky in its true beauty, but the only way to do so is to retract the light pollution that humans have impacted the world

Have you ever travelled to US state like Texas? If you have then you must have witnessed many glittering towns and cities of Texas that has lightened the dark sky and sometimes travellers have the feeling that they are still witnessing a day time due to the extensive use of lights in the cities like Nevada & Houston. Thus, today we are going to study how outdoor lighting Houston affects its citizens. Since it is very well known that outdoor lighting is a striking and attractive way to add security to a home, business and rental property as well as the public area such as parks and waterways that are basic night time attractions for couples, children and for the elderly people. As it is a common knowledge to each and every one of us that outdoor

The approach to the Pluto system over the last few days has yielded previously unexcelled images of the planet, as well as its moon, Charon (pronounced equally as “Sharon” or “Karen”). But Stern promised the next few days will bring forth much better photos, with ten times the resolution of previous images.

The newest high-resolution eye-candy images of Pluto were released by the New Horizons mission team at a press conference today and, again, they did not disappoint. Details flow in and questions continue to mount as the formerly most-mysterious body in the solar system drops her veils. See below for images and video.

Internal Summary/Preview: After discussing the discovery of “Planet X” through the beliefs of Percival Lowell and the actual finding done by Clyde Tombaugh, we will shift to discussing how “Planet X” got the name Pluto.

This mission’s spacecraft is the second designed for NASA’s New Frontiers, with the first being Pluto New Horizons launched in 2006. New Frontiers is a program focused on medium-sized missions that are of crucial importance to the objectives of the Decadal Solar System Exploration Survey. It focuses on the building of a solid understand of planetary science, with priorities set by the Space Studies Board of the National Research Council.

Since ancient times, the universe had captivated people’s imagination and curiosity. With the limitation on technology, early sky watchers were only capable of classifying objects they observed as either a star or a planet. During the twentieth century, with advancement in telescopes to see further into space with more accurate details, scientists were able to find numerous stars and planet like objects within the solar system. Scientists had no trouble classifying objects such as Uranus and Neptune as planets. However, the real trouble came when they discovered a planetary object called Ceres. Objects like Ceres and Pluto behaved similarly to regular planets. Because of the limitations on the technology at the time, it was very difficult
