Energy Star

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…

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…

First, Energy has multiple forms that can switch different states. The two most common forms of energy are, Kinetic and Potential Energy. Kinetic Energy is the energy created when an object is in motion. It can be transferred between two objects if the object has enough energy, therefor it can be from of a collision. Kinetic energy can also be elastic or inelastic energy, however Potential Energy is an energy, but is potentially created before Kinetic Energy. Both types of energy are measured in…

As we arrived to our new four star hotel we felt relieved and felt almost safe. We made our way to the dining area ready to eat a delicious breakfast buffet. I neared a chef that was preparing waffles and she grunted at me in acknowledgement. “ Do you need help?” A young beautiful chinese…

The upper point on the main sequence which is the most densely populated with stars where the red giants seem to begin is called the turnoff point; the exact location of turnoff point indicates the age of the cluster. Deriving the distance and age of M52 We have already identified main sequence, turnoff point, and giant red for M52 shown in figure by comparing with Figure 1. A best fit line this will help to find the distance to open cluster M52 by using the techniques of best fit line. In…

Without the gravitational pull or the attraction a sun exerts on our planets we would just float away from the sun. According to http://earthsky.org/ Inside of spinning disk is a rocky material because all of the gas had joined together and created a star.…

civilizations within the universe right now. R* is the approximate rate of the formation of stars within our galaxy. Fp represents the fraction of stars in the Milky Way that are companioned by other planets. Ne takes the place of the number of planets per sun-like star that have habitable ecospheres, which is what allows for the chemical evolution of life. Fl is what breaks up the planets per sun-like star which obtain inhabiting ecospheres and separates them from the ones that actually do…
