Epicycle theory


In Kepler s day three models existed to explain the observed motions of the wandering stars. However, no clear criteria of physical truthfulness existed to discern which of these models corresponded to the actual, physical universe. Each model could be used to predict the future longitude and latitude of planets in the sky for a few years out. All of them became less accurate…

In the times of the ancient Greek philosopher/astronomers, there was much debate over whether the center of the solar system was the Sun or Earth. Eventually, most early Greek astronomers came upon the idea of a geocentric idea of the solar system. This put the Earth at the center of the System and assumed that the Moon, Sun, and other planets orbited around it (1). A visual…

This is the VOA Special English Technology Report. The Hubble Space Telescope continues to make valuable discoveries after more than twenty years in orbit around Earth. Hubble recently showed a fourth moon orbiting Pluto. Astronomers temporarily named it P4. The moon is the smallest to be discovered around the icy dwarf planet. Astronomers estimate that the moon is from thirteen…
