Two of Jupiter's satellites, Europa and Ganymede, pull Io into an elliptical orbit around Jupiter. Differences in the strength of Jupiter's gravitational pull as the distance between the planet and Io varies causes slight changes in Io's shape. Scientists believe that Io heats up internally when it changes shape.
The Atomic Age, also known as the Atomic Era, is the period of history following the detonation of the first nuclear (atomic) bomb, Trinity, on July 16, 1945 during World War II.
The Atomic Age. The United States did not enter the war until 1941, but as early as 1939 the research on what would become the atomic bomb began. It had been reported by nuclear physicist Niels Bojr that German scientists had achieved atomic fission and the United States was not about to fall behind (Goldstein 5).he effects of the Atomic Age stretched into all realms of American life. Since that August of 1945, many books have been written about the bombings, but the first was written by a man named John Hersey.
