Energy Star

the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it plays an important role in the universe. The street light flickers on above your head, snapping you out of your reverie and reminding you that you still have an essay to write. You sigh, sit up, and walk to your house, the stars quickly…

classification of stars and continues to do so in today’s time. Annie Jump Cannon’s legacy will carry on lasting a lifetime! The first letters of each word in the phrase represents the seven main types of stars. Starting with ”‘O,” these stars are very young, blue, hot, massive and extremely bright star. This type of star is very uncommon similar to the “B” and “A” stars. These stars get their energy from nuclear fusion, as they convert Hydrogen to Helium. As these massive stars begin to die…

Telescope and the European Southern Observatory’s Very Large Telescope have shown researchers a very interesting image. A set of ripples traveling through the protoplanetary disc of a star. This unforeseen and unexpected visual was spotted by a team of research as they analyzed the dust and debris surrounding the star AU Microscopii, or AU Mic, by the use of the SPHERE instrument of the VLT. Astronomers observe AU Mic in hopes of better grasping how planets form and evolve through the young…

Astronomy in Yosemite The Sun The sun is a star located at the center of the universe, and without it, there would be no life on Earth. It is the most important source of energy for humans as it provides us light, heat, and more. It can reach surface temperatures of about 5,276 degrees Celsius, and 10,340 degrees Fahrenheit. The composition of the Sun changes slowly as hydrogen is converted into helium in its core; however, it is currently made up of around 70% hydrogen, 28% helium, and less…

using two different methods: by studying the oldest objects within the universe and measuring how fast it is expanding. Experts agree that the universe cannot be younger than the objects contained inside of it. By determining the ages of the oldest stars, scientists are able to put a age limit on the universe which is 13.7 billion years old. A forever expanding universe? The expansion of the universe depends on how much matter the universe contains. Scientists predict that if there is enough…

the Approach of Using Hydrogen and Helium Emission Spectra with the Rydberg Equation to Determine the Ionization Energy of Helium Michelle Plavnik Department of Chemistry, Emory University, Atlanta, GA, 30322, United States PAGE 2 ABSTRACT: The purpose of this lab is to determine how accurate the Rydberg equation is at modeling helium transitions and finding the ionization energy from those transitions. To accomplish this aim, the spectra of hydrogen and helium were taken. According to the…

NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While NGC 582 was an easy object in the 18 inch, the PGC galaxy was not seen with certainty. A galaxy is, by definition, any large collection of stars that can be recognized as a distinct physical entity. In terms of the number of stars, a small 'dwarf irregular'…

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…

Really, it isn't as bad as many think. At CERN (the main producer of antimatter) their storage capacity for antimatter when full couldn’t even give off as much energy as a calorie in food. As of right now, CERN could not make enough antimatter at a time to cause a big explosion. The only problem is what if CERN want to mass produce antimatter in the future and use it for various tasks? They would have to try to…

Stage Four: Protostar By this stage of the stars evolution, 100,000 years after the process began, it can now be plotted on the Hertzsprung-Russell diagram, which is used to compare the many different stars. Although it is still not fully formed, we are able to determine the type of star it will become based on its luminosity and temperature. In the nucleus of the condensed cloud, which could now fit within the orbit of Mercury at less than 58,000,000 km wide, electrons and protons are ripped…
