Stars

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,…

to two main factors. Fewer stars (the universe's light bulbs) are being made and our universe is expanding. “More stars are dying then being born” we know this because after looking 2 billion years into the past we have seen a brighter universe, this has many implications. Since stars are responsible for almost all the light and energy in our universe a declining of them means a declining of their produce which will darken and freeze the universe. The absence of stars is a…

Christopher Tran EAS 1601: Writing Assignment 1 13 October 2015 Why Giant-Planet Cores do not Spiral Towards their Parent Stars http://www.nature.com/nature/journal/v520/n7545/full/520040a.html Why are gas giant planets of exoplanetary systems at a distance of at least one astronomical unit from their host stars? As we learned in class, the gas giants form by accreting and colliding with smaller solid bodies from the disk. According to Duncan, this process of accretion can occur relatively fast…

it is never certain. In his romantic poem “Bright Star, would I were stedfast as thou art,” John Keats admires the steadfastness of the star, and how the speaker wishes he could be in the same situation as the star with his love. On the contrary, Robert Frost, in his poem “Choose Something Like a Star,” admires the star for its uncertain nature and focuses on humanity’s need for reassurance from a high power. Although both poets address the star initially, a closer examination of each poem…

beings can feel true joy without first experiencing sadness with his use of stars throughout his poetry to signify a light in the dark. Neruda uses a star motif to indicate a positive feeling or outlook surrounded by the harsh darkness of negativity. Neruda suggests that there can only be light if there is also darkness and the emotional highs and lows in life must ultimately balance out. In his poems, Neruda uses the motif of stars to portray positive emotions in contrast to the negative…

The star outside your spaceship's windshield is a spectacular sight. HR 5171 A is a fireball 1,300 times larger than the Earth's sun. It's so big that if it were in our sun's position, it would swallow up Earth beneath its 10,000°F surface. To look at it from your spaceship, you have to wear special goggles--this star is almost a million times brighter than our sun. As you watch HR 5171A burn, you notice something strange. An object is peeking over the horizon, growing larger and larger. It's…

Star Journal Year 1: Today my nebula started collapsing. A star a few light years away exploded in a supernova, which started my formation process. I’m feeling changes in my gravitational pull, I think it’s getting stronger. I’m so excited, in a few million years, I’m going to be a protostar! I can feel all of the gas and dust starting to form around me, slowly condensing. It’s making a huge spinning disk around me, and the cloud of hydrogen is getting smaller. My core isn’t hot enough to start…

Studies have shown that when two strangers are forced to talk and maintain eye contact, it can make them fall in love. This is what happened between Daniel Bae and Natasha Kingsley in the book The Sun Is Also a Star, by Nicola Yoon. Daniel is a Korean-American poet and Natasha is an undocumented immigrant who is being deported to Jamaica in twelve hours. When they first meet Daniel feels an instant connection, so he tries to convince Natasha that they are in love by following her around New…

Stars are an appealing component of our universe. Because of our scientific advances, we know more about stars than ever before. They are born, they live, and then they die. How does this process work, though? The answer lies within thermodynamics. Thermodynamics has helped us understand how stars transfer energy and heat. Thermodynamics is a subject of physics that is concerned with heat and temperature. It is used to describe bodies of matter and their internal energy. Thermodynamics helps us…

How do stars form? The stars were born among the dust and scattered throughout the most galaxies. There is an example of dust cloud which is the Orion Nebula.The turbulence in the depths of these clouds produces enough mass of knots.Because its own gravitational attraction,and the gas and dust can begin to collapse. Then the material at the center begin to heat up which is known as protostar . The heart of the collapsing cloud will one day become a star. Since stars are formed from…
