The Andromeda Galaxy (M31) is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen unaided from the Earth. currently, the Earth is closest to the sun in the northern hemisphere winter, which makes the winters there less severe (Thomas, 2002). Minerals. (c) change in orientation of the Earth’s axis. In 2011 Neptune completed its first orbit since its discovery in 1846. What laws govern its evolution ? Answer: (a) Johannes Kepler, working with data painstakingly collected by Tycho Brahe without the aid of a telescope, developed three laws which described the motion of the planets across the sky. CSS was never that easy. (c) Neptune 112) Which one of the following planets has no moons?

The Big Bang theory is the model describes how the universe expanded from a very high-density and high-temperature state,and offers a comprehensive explanation for a broad range of phenomena which including the abundance of light elements, the cosmic microwave background (CMB), Hubble’s law and large scale structure. Quasars: In the 1930’s, Edwin Hubble discovered that all galaxies have a positive redshift. But recent research in physics makes it clear that things aren't really this simple. (b) The photosphere The change in the axis location changes the dates of perihelion (closest distance from sun) and aphelion (farthest distance from sun), and this increases the seasonal contrast in one hemisphere while decreasing it in the other hemisphere ( Kaufman, 2002).
