Galileo Ganymede's Influence On Galilean Moon

Galileo has been credited with the confirmation of the phases of Venus, the discovery of the four largest satellites of Jupiter, and the observation and analysis of sunspots. He also worked in mathematics and with technology, helping to improve the military compass. Galileo was a renaissance man.

Galileo spacecraft first discovered the four largest moon of Jupiter, called Io, Europa, Ganymede and Ganymede and Callisto. Ganymede is the largest moon in the Solar System Atmosphere And Planetary Composition: Temperature Range: The cloud-tops average 120 K=153*C=-244*F. Atmosphere: Jupiter is a gaseous planet; it does not have a solid surface like the Earth does (but probably has a solid, rocky core 10 to 15 times the mass of the Earth). When we look at Jupiter, we are seeing icy clouds of gases moving at high speeds in the atmosphere. Jupiter's atmosphere is composed of about 90% hydrogen and 10% helium.

The telescope is an optical instrument designed to make distant objects appear nearer. It contains an arrangement of lenses or mirrors or both that gathers visible light, permitting direct observation or photographic recording of distant objects. (Lacki, B. C. 2011). With the use of telescopes we have been able to learn a lot more about the planets in our universe. It has helped us understand about some of the history of everything around us. Also it has been able to track asteroids and comets or any randomly flying objet in outer space that might become threatening to our planet.

Locked in 1:2:4 orbital cycle with Europa and Io. For every single orbit of Ganymede, Europa orbits Jupiter 2 times and Io orbits 4 times.

During the time of Galileo, the church was very strict with physicists who believed in the Copernican model. This is exactly the position that Galileo found himself in. In 1600 Galileo began making his own telescope. He became the first person to point one at the night sky. What staggered him the most by doing this was the sheer volume of stars that were not visible with the naked eye. Galileo used his telescope to make many discoveries; one of these is the discovery of Jupiter’s four moons. He even plotted and tracked there rotations around Jupiter. The main thing however, was that Jupiter even had moons, this was proof that the geocentric model was incorrect and that this discovery was in favour of the Copernican model.

Meridian has been manufacturing fine telescopes for 80 years and has developed a well-earned reputation for quality craftsmanship. The company itself produces and sells two distinct lines of telescopes, which are produced in its 200,000 square feet facility. Furthermore, both lines have been developed to appeal to distinct target audiences who have an interest in the company’s products. The older line, for which there has been steady demand, consists of small professional telescopes that ultimately have laid the foundation for Meridian’s strong reputation. Following the success of

Galileo created a telescope and turned it to the sky. As a result of his observations, our solar system was seen in a way that had never been imaginable before. He discovered that the Earth was not at the center of the solar system, but instead the earth revolved around the sun. Prior to this discovery, the church adopted the idea that the Earth was at the center of the solar system and everything revolved around it. This discovery altered our view of science and the church in large and small

Without seeing this device, Galileo successfully built his own telescope. after making some improvements, he used his telescope to study to heavens in 1609. In 1610 , Galileo published a series of newsletters called Starry messenger, which described his astonishing observations. Galileo announced that jupiter had four moons, and that the sun had dark spots.

Galileo started off the mission by launching off on October 18th, 1989 at Kennedy Space Center, Florida. The spacecraft entered Jupiter’s orbit on December 8, 1995. Its mission ended and it decayed into the atmosphere on September 21, 2003. Galileo also discovered various meaningful results such as certain measurements in the atmosphere. For example, the density and temperature of the upper atmosphere is greatly higher than expected. On the other hand, the lower atmosphere’s temperature is closer to what was expected. Additionally, it was analyzed that the deep atmosphere was dryer than expected. Furthermore, it was discovered that the scientific instruments on the spacecraft worked successfully. While on the mission, Galileo detected a radiation belt between Jupiter’s ring and upper atmospheric layers. It is believed that Jupiter’s radiation belt is 10 times stronger than Van Allen, which is the radiation belt near Earth. Galileo also studied the winds on Jupiter. It found out that the winds are strong alternating east-west jetstreams, which is dissimilar to Earth’s wind system. The winds on Jupiter below the clouds are 540km/hr (330mph). On Galileo’s mission, there were many important firsts. Galileo had a close flyby of an asteroid, Gaspra. Galileo also discovered a satellite of an asteroid. The satellite was named Dactyl and the asteroid was Ida. Galileo was also the first atmospheric probe to enter Jupiter's atmosphere. The spacecraft was also the first to enter Jupiter’s orbit and go around it. Galileo also directly observed a comet impacting a planet. The comet was Shoemaker-Levy 9. But by far, the most important discovery was discovering liquid ocean water under Europa’s (one of Jupiter’s moons)

The use of the telescope led him to discover new characteristics of space and the solar system. He discovered Jupiter’s four largest moons and the rings of Saturn. He also discovered that the Milky Way galaxy is comprised of stars. The observation of mountains on the moon was made by Galileo as well. He also made numerous discoveries within these discoveries.

Scientists came up with a solution to correct the defect in which they came up with a replacement "contact" lens called COSTAR. The Corrective Optics Space Telescope Axial Replacement consisted of several minute mirrors that would intercept the beam of the flawed mirror and relay the corrected beam to the scientific instruments at the focus of the mirror.

Galileo’s observational discoveries in astronomy allowed for the basis to begin discrediting the old ideas in favor of a new understanding of the universe. The longstanding way of thought in astronomy favored a spherically rotating universe around the Earth with unchanging and perfectly symmetrical constellations and planets. The contemporaries of Galileo believed, for example, that the moon had the face of a shiny, polished sphere, whereas Galileo showed that the surface of the moon to be imperfect with rough mountainous areas along with deep valleys (or “seas” as he called them) marked with dark sports (Frova 162). This surface very much paralleled the rough surface of the Earth (meaning that Earth’s surface was not unique). Also with his improved telescope, Galileo was capable of viewing the stars with much more clarity. Galileo discovered newly formed stars and star clusters, which challenged the Aristotelian philosophy of an ageless universe. Additionally, Galileo observed four of Jupiter’s largest moons orbiting around the planet (Frova 179). His observations of Jupiter’s satellites did not agree with the idea that all heavenly bodies must rotate around a central Earth. Finally, and arguably most important, Galileo showed Venus’s phases and

As proposed in an article posted on amazing space.org, “The telescope, a basic reflector with a 94.5 in (2.4 meters) mirror.” While also having being a second mirror that the light bounces to to. Within that mirror, many instruments were compacted together that allowed for clear and visible views in infrared and ultraviolet light. It was different compared to any other ground based telescope whereas it allowed astronomers to observe and witness details that had never been seen before due to Earth being in the way for those other telescopes. The telescope revolves around the earth completely every ninety-seven minutes at the speed of five miles per second, allowing for many observations in space. The observations occur when light hits the main mirror and then bounces towards the second mirror in which the second one focuses the light. The telescope began to be created in 1977 and was originally supposed to launch during the year of 1985. Unfortunately an accident had occurred when a space shuttle challenger exploded and flights into space took a halt. It was finally launched on April 4th of 1990 once the halt had stopped. The improved observations had begun and the history of astronomy had changed. Unfortunately there were some minor setbacks that had to be dealt with. One setback was that the primary mirror was ground incorrectly in which the curve of it was too flat. It was off just

This could mean that there is water underneath the surface of this moon, but what else lies beyond? Doppler tracking data obtained during four flybys done by Galileo (spacecraft) past Europa exposed the moon’s axial movement of inertia, suggesting a partial compression of material in the direction of Europa’s epicenter. Three-layer models created by reasonable arrangements propose that Europa contains an outermost water (H2O) layer and has a density close to 80 to 200 kilometers thick, a middle layer of a silicate rock mantle, and maybe a biphasic material (Fe-FeS) metallic core. Models created without a metallic core are steady with the data but need high silicate densities. More credible models have a metallic core thirty to fifty percent of Europa’s radius in magnitude and a silicate mantle
