CELESTIAL BODIES AND BEINGS ASTROLOGY What is astrology? It is astronomy that supposed to influence lives and behavior of people. Its definition includes the term astronomy. Before going into what astrology is all about, explaining what astronomy is will let you understand astrology better. So what is astronomy? It is the study of the night sky – the planets, moons, stars, galaxies, and other celestial bodies. Incorporating the effects of these celestial bodies to people, results to astrology. There are numerous movements and activities happening outside of the Earth. Their effects may or may not benefit us. These celestial bodies can also amaze us in different ways. Starting off with the different celestial bodies is the universe itself. The universe is everything that exists, from the Earth beneath our feet to the farthest stars and the other parts of the universe(1001 Facts About Space). The universe contains a vast number of galaxies, which also contains a number of different celestial bodies. Fig. 1 The Universe Consists of a huge number of galaxies, but is mostly composed of empty spaces. Speaking of galaxies, there are numerous galaxies in the universe. Seen from the space, the Milky Way galaxy, which is where our planet is located, is just one of the hundreds, or even thousands of galaxies that exist. The Milky Way consists of many other space bodies such as the 9 planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto, which was later declared to be a dwarf planet. The galaxy also contains comets, asteroids, stars, and other celestial bodies. Other than galaxies, there are many other celestial objects present in space. Some of these are black holes, nebulae, neutron stars, galaxy clusters, and supernovas. A supernova is an interstellar explosion whereas a supergiant star has exploded, leaving it bright for a week or even a month. After a supernova is a nebula or nebulae(pl). A nebula is the remnants of a massive supernova explosion. The most famous nebula is the Crab Nebula. According to NASA, the Chinese astronomers noted it in the constellation of Taurus in the year 1054 AD. Supernova Fig. 2 (upper right)The Crab Nebula (lower right) The most detailed view of the Crab Nebula caught by Neutron stars are ancient remnants of stars that have already died or have exploded Telescope and dispersed in the vast space. It is a result of a supernova. Neutron stars have (Space.com) extremely strong gravitational pull. When formed, they rotate on space. This rotation speeds up when the particles compress and shrink(National Geographic). The Hubble Space Fig. 3 An image of a Neutron Star courtesy of NASA/Andrew Fruchter (STScI). What are galaxy clustered together. clusters? These are merely groups of galaxies Fig. 4 A galaxy cluster or superclusters. Fascinating Fact: One film of superclusters makes up a vast structure called the Great Wall, which is the largest structure in the universe-over 700 million light-years long, but just 30 million thick. (1000 Facts On Space) Next in line is what is called the Black Hole. What is a black hole? It is something that is so dense which has a strong gravitational pull allowing it to suck in everything, including light. As it was stated in the book 1001 Facts About Space, black holes are invisible, but are believed to be surrounded by a spinning accretion disk of material being drawn to the black hole.

EXTRATERRESTRIALS Do you believe in aliens? Do aliens exist in your imagination? Extraterrestrial is better known as aliens, others call them as strangers, green horn, little green creature and others. But what do extraterrestrial mean? Like other sciences or studies, extraterrestrial have three(3) of them and these terms for some who is not aware of this topic might think this is alien: Xenobiology, Exobiology or Astrobiology is the study of the life forms outside Earth, specifically Xenobiology. Xenobiology comes from the Greek word “xenos” which means “strangers, guest”(en.wikitionary.org), while Exobiology(accdg. To Merriam-Webster) is derived from the word “exo” which pertains as the external or out of Earth branch of biology that deals with the search for extraterrestrial life and the effects of extraterrestrial surroundings on Earth, last but not the least is Astrobiology which comes from the root word “astro” which signifies it is the study of stars, celestial objects or outer space, further it is the branch of biology concerned with the study of life on earth and in space(en.wikipedia.com). Extraterrestrial life is life that may exist and originate outside the planet Earth, the only place in the universe currently known by humans to support life. Most scientists hold that if extraterrestrial life exists, its evolution would have occurred independently in different places in the universe. An alternative response to this suggests that life in the universe could have stemmed from a smaller number of points of origin, and then spread across the universe, from one planet to another planet by adapting to its surrounding and environment.(http://www.sciencedaily.com) Humanity has arrived at a special but bittersweet moment. For thousands of years, people had looked up at the night sky wondering whether they were alone in these starry depths, whether there was any place like Earth out there, and how they would ever know. In the next 20 years astronomers now have evidence that there are more planets than stars out there. Milky Way Galaxy, is the galaxy that contains our Solar System, its size is 100,000-120,000 light years (a unit of astronomical distance equivalent to the distance that light travels in one year, which is approximately 6 trillion miles for 1 light year) in diameter. Our dear Earth is located 27,000 light years from the center of the galaxy. It is composed of 100-400 billion stars and many planets too. In 1920 astronomers think that astronomers thought that all of the stars in the universe were contained inside of the Milky Way, but in later studies by Edwin Hubble he said that Milky Way is just one of the billions or even trillion galaxies around the universe, thus it is not impossible for life forms to develop or adapt to other planets across our galaxy or even other galaxies. http://en.wikipedia.com What do us humans think how do aliens look like? First of all, almost everyone of us think that they come from Mars, thus calling them Marsians, and we think that they look like small human-like form with long arms and fingers, color green or flesh all around its body and is very thin and slender in shape, has a very big round head and big eyes which are pure black in color. There are places here in Earth that shows that aliens exist or shows alien activities and alien-made marvels. Area 51 is one of the most known areas that give humans the idea that extraterrestrial bodies exist, because this place is world known for hiding alien sightings like alien bodies that are captured or retrieved from their space ships and other apparatuses that aliens use. Another is the Stonehenge, which they believe that these raised stones that are in a circle form is built for a reason, and that is reason is it is used by alien spaceship or spacecraft as a landing pad.
