Similarities Between Europa Ganymede And Callisto
Europa, Ganymede, and Callisto are just three of Jupiter’s 63 known moons. These three moons are special, as scientists believe that there could be marine life on them. Scientists realized that Io, another moon to Jupiter, was heated internally by tidal heating. Tidal heating occurs through friction when orbital and rotational energy are dissipated as heat in the ocean or the interior of a planet. From this information, scientists concluded that the other Galilean moons must also be heated internally by tidal heating. It was found that Europa, Ganymede, and Callisto also have large bodies of water which are mostly frozen. This information along with tidal heating, help scientists believe there is marine life on Europa, Ganymede, and Callisto.

    On Hoagland’s site, he flatly claims to have originated the idea of life in the oceans of Europa in his Star and Sky article. (One should note that Star and Sky is not a scientific journal. It is a hobbyist/enthusiast magazine). This theory had been published nine years previous in the scientific journal Icarus by Dr. John Lewis. Also one year before Hoagland was published Dr. Benton Clark gave a speech at Ames Research Center about the potential for life in Europa’s waters. Hoagland has been presented with these facts, yet does not correct his claims to be the originator of the…

    The planet's surface temperature is 712 K (439 °C). This temperature is higher than expected if the planet were only heated by radiation from its star.Whatever forces, tidal effects deliver to the planet, it does not affect its temperature a lot. A greenhouse effect could raise the temperature to much higher degrees than 520–620 K.…

    A villain is commonly illustrated as a sinister character at odds with the hero of the story, and is often depicted as unlikeable and untrustworthy. However, villains are known to possess characteristics such as strength, courage and determination, all of which are critical to their ability to oppose the hero. Using these traits to compare both antagonists, it is clear that Magneto is the more successful villain, displaying these attributes more consistently and capably. Strength is a trait found within both Grendel and Magneto, with Grendel being described throughout the myth as large and powerful enough to bring upon the demise of any innocent man. This is shown when Grendel decapitates the warrior Hondisico.…

    Jupiter is the largest planet in our solar system. It is twice as large as all the other planets combined. It has 28 known satellites. The earliest discovered moons date back to 1610 and were discovered by Galileo. This is of interest because a future mission to Jupiter is named after this astronomer. Most of the remaining moons were discovered in the 20th century with advancement of technology. Some are discovered using better telescopes and others with missions directed towards Jupiter. Some of the more recently discovered moons are yet to be named. All that we know of Jupiter couldn 't possibly have come form just observation. Some have come by spacecraft passing by Jupiter on their way to other missions and some of the most comprehensive…

    Witches have always fascinated people, even as they feared them. This fascination extends as far back as ancient times, where the witches Medea and Circe make their debut. Both are depicted as dark creatures, redeemed only by their assistance of a male hero. Upon further inspection, though, these two are separate in both how they approach magic, and in the very source of their magic. The practical aspects of magic may remain relatively unchanged, the way the magic is used can be as different as day and night, as Circe and Medea.…

    On Earth, water exists in the three primary states of matter; liquid, solid, and gas. The distance of Earth from the Sun, by fortunate coincidence, is such that the amount of energy arriving at the surface of most of the planet is sufficient to elevate the ambient temperature to levels above the freezing point of water, yet insufficient to cause all of the water to evaporate into the gaseous state. The capacity of water to store large quantities of heat energy heavily influences the nature of the global climate. The presence of large bodies of liquid water and the atmosphere restrict the range of temperature fluctuations on Earth. These conditions have allowed the existence of the fourth component of Earth's system, the biosphere.…
