Five-pointed star

Stars are complex and giant balls of matter that have many things to understand about. Stars are born of gas and dust and have a life cycle based on their original mass. All stars start out in their main sequence, but the first difference between the mass of stars is when they stop producing energy. The low-mass stars become giant, and the high-mass stars become super giant. For low-mass, the star then becomes a planetary nebula, then finally a white dwarf. High-mass stars become a supernova, a…

NASA has recently discovered a new planet Yelger in the Andromeda Galaxy. It is the right distance from the sun to support life. It is the same size and mass as Earth. It takes 700 Earth days to revolve around the sun(360 on Earth), and takes 20 Earth hours to rotate around its axis(24 on Earth). It’s temperatures are about the same as on Earth, and has a tilt of 45º. It’s moon is the same distance away from Earth but it twice the mass and size. Because Yelger takes 20 hours to rotate on it’s…

Supernova can occur in one of two ways, either near the end of the star life or in a binary star system. Inside of a binary star system one of the stars would need to be a white dwarf which is a star who has depleted most of its energy and begins to take away energy from the other star in the system ("What Is a Supernova?"). If it were too depleted too much energy from the other star it would begin to go supernova due to raising its core temperature, igniting carbon fusion…

characteristics in the star. The Vega star is 25 light years away from the earth and the mass is 2.1 times bigger than the sun. It is about 455 million years old and each rotation period is 12.5 hours. The diameter is about 2.2 million miles, which is 2.5 times the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main sequence star, it fuses hydrogen…

Staples, stars are used to symbolize hope in family for one character, Najmah. (BS-2) Stars are similarly used to represent faith in family for another character, Nusrat. (BS-3) When Najmah and Nusrat are together, however, stars are used to represent their peace with the family they’ve lost. (TS) It is clear that in the novel Under The Persimmon Tree by Suzanne Fisher Staples, stars are used to symbolize hope or faith in family for both main characters, Nusrat and Najmah.…

In the daily speech colliding is a word used to describe, when it is two (visible) objects, something is “hit by accident when moving”1, but when it is about galaxies it is not the stars or the solar systems that are colliding. In this subject it is the gravitational fields of the involved galaxies in a interaction that can be called that they are in collision. As this is galaxies the spacing and the sheer size makes the chance of…

Every February my family and I attend the Parker 425. The Parker 425 is an off road race. The events of the race start on Thursday and will end on Sunday. The event is located in Parker Arizona. The entire weekend is packed full of excitement and adrenaline. On Thursday the event will start with the time trials The time trials are how the starting positions are selected. Each of the racers will take turns at running the course. The times are logged and then placed in order from fastest to…

An astronomical star catalogue lists stars by number according to different criteria (such as their magnitude), which can provide insight into the positions of stars, how they change over time, and even the history and culture of the astronomers who create these catalogues. As early as the 2nd millennium B.C.E, star catalogues have been kept (Van der Waerden); they can be seen all over the world and across cultures, increasing in breadth over time as the technology of telescopes advanced and…

she discovered 300 variable stars and invented her own system of classification, which became the universal standard, she listed around 350,000 stars. Annie Jump Cannon died on April 13, 1941 in Cambridge, Massachusetts at the age of 77. Annie Jump Cannon’s father was Wilson Cannon, a Delaware shipbuilder and state senator, her mother was Mary Jump, Annie was the oldest daughter. She was first taught about constellations, which became the main source of interest to stars for Annie, by her…

Astronomy is an ongoing process. It is always changing and improving as we discover new stellar objects and use more advanced technology. For example, people once believed that the Earth was flat, and the sun and other planets orbited around us. As we advanced in technology, we proved both of these ideas to be false. Even today there is still work to be done, ideas and theories to confirm and disprove, and plenty of other things to explore. One scientific discovery that influence society was…
