       Exercise 5

      Astronomers carry out observations and perform calculations. Observations are carried out either with telescopes or with the unaided eye. Everybody is an astronomer in fact, since everybody looks at the sky. Looking at the sky with an unaided eye reveals several objects.

      Since the sunlight covers the entire sky, it is impossible to make clear observations in the sky during the daytime. Observations must be carried out nighttime in order to see celestial objects. The most obvious one of these objects is the Moon with its dimensions apparently the same as the Sun.

      Now get ready for the show of light in the night sky. The twinkling, point-like light sources are stars, many of which are just like our Sun, but appearing very small and faint due to the very large distances over which their light travels to reach us. Some stars are even more gigantic than the Sun and there are stars so colossal that they are a million times brighter than the Sun.

      There are also a few other objects that have the appearance of a star, but they do not twinkle. These objects are the planets of our solar system. It is not possible to see all the planets with the unaided eye. A careful observer can make out five planets of our solar system: Mercury, Venus, Mars, Jupiter, and Saturn.

      An observer may see a broad, diffuse band of light through the sky on a clear moonless night. This band is the Milky Way galaxy that consists of about 400 billion stars, and clouds of interstellar gas and dust. There are billions of galaxies in the universe, but not all are visible with the naked eye. Meteors are occasional visitors, which may be observed with the naked eye.

      They are seen as brief, falling flashes of light. The other occasional members of our sky are comets. Comets revolve around the Sun with constant periods. The most famous comet is the Halley’s Comet, which passed very close to the Earth in 1986.

      ‘The entire universe is rotating around the Earth!’ This debate persisted during the ancient times based on the idea that the Earth was at the centre of the universe. Now it is known that the Earth is not at the centre of the universe but only appears to be rotating around the Earth. The motion is actually that of the Earth around its axis, so the universe is rotating relative to the Earth. Since we are making our observations in the reference frame of the Earth, we perceive the universe to be in motion.

      Each revolution of the Earth around its rotational axis corresponds to one revolution of the objects in the sky around the Earth. A long exposure photograph clarifies this motion. We can conclude that the entire universe appears to be in circular motion around the Earth. During the Earth’s СКАЧАТЬ
