Gemini Telescope And The Supernova Legacy Survey Essay

Gemini Telescope And The Supernova Legacy Survey - Essay Example The Gemini telescope has been used by the partner countries as a tool of astronomical research. It provides world-class observing equipment of the skies for the astronomers. Each country in the partnership is awarded observational time depending on the scientific merit and contribution towards the operation of the machine. The telescopes incorporate advanced technology in order to produce high quality of images. This includes the use of adaptive optics, laser guide stars, multi-object spectroscopy, and multi-conjugate adaptive optics. In addition, the telescope is made using a silver coating that is essential for the protection of the primary and secondary mirror. The location of the telescopes provides superb viewing conditions of the sky. The telescope system has low emissivity coatings and an effective mirror cleaning program. These enable the machine to pick clear images. Each Gemini telescope has an adaptive optics setup further adding to the quality of images that the center captures. The telescopes can perform long-slit spectroscopy, multi-object spectroscopy, integral field spectroscopy and imaging at optical wavelengths. Infrared optimization and silver coating allow clear observations at the middle of the infrared spectrum. Proximity to infrared spectrograph boosts the sensitivity for point object and sources. The instrument is also known as a Multi-Conjugate optics adaptive system. It employs five guide stars to provide clarity over a large area captured. The guide stars are artificially made by laser (Simons 123). A fundamental discovery that has been made by the Gemini Observatory telescope is a multi-planet system around a star. Images from the Gemini observatory helped the international team to discover two of the planets in the year 2007 (Howell 1191).

Cooling the Lava - Assignment Example In the same period, strange masses of ice drift obstructed harbors and caused wide destruction. Suddenly, a fissure opened in the community outskirts and a lava curtain fountained high into the sky. The crew courageously watered the lava front as a garden. The water reduced the heat of the lava and a chilled lava wall was created to dam the red lava behind. As the lava moved below the air, the skin of glass developed. The skin could be repeatedly broken by the liquid motion under and tinkled (John A. McPhee. 104). Â  The crew used bulldozers to flatten a jagged surface glass and make way for the crew to move heavy pipes. Some individuals could catch fire and cool themselves with water and return to work. There was no any minute to waste as the crew had declared fight against the fatal lava. It seemed like the crew was in combat. The eruption vapors choked the people, but no one dared to put the tools down. They focused to contain the lava and turn it black. The falling ash formed a fog that obstructed visibility but could not deter their effort. They steadily watered and cooled the advancing lava from the summit until they stopped the flow.
