Cepheid Variable Stars are large and luminous yellow stars in space known to sporadically change size and temperature resulting in pulsing variations in brightness and thus, inconsistent levels of luminosity. There are two types of Cepheid Variable Stars; Type 1 Cepheids (or classical) which are high mass stars with smaller pulsating periods and Type 2 Cepheids which are lower mass stars with greater pulsation periods. All Cepheid Variable Stars, named after the first observed star of this type,…

Since I was little, I have been hypnotized by the stars. Each star twinkles in such a spectacular way, that when I would look outside my window, with my teddy bear in hand, I would have trouble picking my favorite one. The stars inspired me to be curious, to look for the same light they gave off in the world around me, and to love myself just like I loved the stars. As I prepare for college, the idea of college as a whole reminds me of the stars. The promise of a bright future, the chance to…

Alien Hunting A giant telescope has been built in order to find extra terrestrial life. It took a total of 5 years to build and cost 180 million dollars. It takes up as much space as 30 football fields. It was built in China by the Chinese Government, Mainly using drones. It was built as far away from civilization as possible as to not get interference. It is called the Five hundred meter Aperture Spherical Telescope or FAST for short. Fast was designed to detect strange occurrences in space.…

Purpose: To use Parallax and triangulation to measure the indirect distance between two points. Hypothesis: If a long distance is measured using triangulation then it will produce an accurate measurement. Materials: 1. Protractor 2. Ruler 3. Tape measure 4. Table or desk 5. Paper 6. Pencil 7. Masking tape Procedure: 1. Gather all of your materials 2. Clear off your table or desk 3. Place an object at one end of the desk (image A). Using masking tape, label this point C. 4. From the end…

100 billion stars in our galaxy alone. Space is never ending filled with countless amounts of galaxies that we cannot even begin to understand. There are so many stars and so many lives. They have different sizes and shapes and they can turn into different things after they die based on their size and shape. The exact definition of a star is a fixed luminous point in the night sky that is a large, remote incandescent body like the sun, however, stars are much more than that. Stars are related…

group of stars movement that orbits an area in a space. In other words, when gas enters stellar black hole from a companion star, the gas twists inwards, heating at a very high temperature and producing huge amounts of radiation that can be noticed from earthbound and earth-orbiting telescopes. Locations that black holes can easily be found have been identified. One likely area is at the middle of galaxies. At this region the concentration of stars increases the possibility of larger stars to…

The Sun is a massive, white ball of gas that fuels the solar system. Without it, life wouldn’t be able to survive on earth. It has lived for billions of years, providing energy and light. Nothing can live without it. The Sun, which is also called Sol, is estimated to be 4.6 billion years old with up to five billion years left in its life. It is currently in its yellow dwarf phase of life. It is located in the Milky Way galaxy in a spiral arm known as the Orion Arm. The Sun orbits the center of…

myth/legend is very interesting and it is a very unique creature to me. The Pegasus lies in the Northern Hemisphere and it is the seventh largest constellation in the sky, occupying an area of 1121 square degrees. This constellation is made up with 9 stars--Scheat, Matar, Salm, Algenib and Markab. The brightest is Markab. This constellation's name came from Pegasus, a white winged horse. The most famous/well-known Greek myth involving Pegasus is the one of Bellerophon, the hero who was sent by…

occur in the universe, there are not many that equal the power or beauty of a supernova. Supernovas occur at the end of the star’s life cycle as the star depletes its fuel. According to NASA, as the star runs out of fuel, a portion of the stars mass flows towards the core. This causes the core to grow and eventually due to the gravitational forces of the star, collapses the core causing a spectacular explosion. While it is theorized that a supernova occurs once every second in the universe, few…

Fundamentals of Orbital Mechanics This chapter applies the principles of physics for describing motion of artificial satellites and planets which are moving under the influence of gravitation force. It also presents an accurate gravity model for flight dynamic applications (for use in subsequent chapters). 2.1 Kepler’s Laws of Planetary Motion In 1609 Kepler has presented his three laws for describing motion of planets around the Sun. These laws are empirical because Kepler has found them…
