eyes and the face attained beauty as we define it. Then he grew transparent wings that were radiating hues of gold and started to levitate, increasing his speed and fading into a sphere of incandescent light made of iridescent waves unleashing bright stars.…
Space is extraordinary! It is full of planets, stars, and many other things. There are several different hypotheses that were proposed on how the solar system was created. One of these hypotheses is the Nebular that was formulated by Pierre-Simon de Laplace in 1796. Many years later, in the 1900s, the Protoplanet hypothesis was proposed by Carl von Weizsäcker and Gerard Kuiper. Forest Moulton and Thomas Chamberlin proposed the Planetesimal hypothesis in 1905. The Nebular hypothesis starts…
Cosmos episode 13, “Unafraid of the dark”, begins by talking about the vast amount of scrolls and information that was kept in the library of Alexandria. Many of the books and scrolls were lost when the mob attacked and destroyed the library. This is shocking because of all the history of Ancient times that he's been lost due to the destruction of these books. Although we lost many discoveries, we as humans continue to learn new information about the universe. This begins the discovery of…
Before the Earth took the form of beauty and light it was formless and without the brightness of light. The terrors of this sphere of blank were many, and their numbers outnumber the stars that would one day occupy the sky. Beasts of storms that were to be and never occured roamed free of prison. Nothing to entomb them into the all encompassing pit that would one day swallow them all. The time described is before the Primordials of the universe created the first generation of gods, the gods…
It is classified as a Yellow Dwarf Star and has a surface temperature of 5,000 to 5,700 degrees celsius. But despite of this, there are many other stars in space that dwarf our Sun. The Sun also has an interesting history, from when it has been formed to the present time. The Sun is not the only star in the Milky Way. Another star close to Earth is Alpha Centauri C, also called Proxima Centauri. Unlike the Sun, Proxima Centauri is a red dwarf star. Every star has a spectral type. The Sun is a…
Using the most the most comprehensive telescope ever created astronomers have found that the universe is slowly dying. By looking at a lot of data, 200,000 galaxies in 21 wavelengths, they have found out that our universe was producing two times the amount of energy 2 billion years ago, in comparison to today. Eventually our universe with be cold, empty, darkness, but we do not have to worry because scientists suspect that our sun will burn out long before our universe does. The area of…
today. Those two things are hydrogen and helium. The temperature it normally stays at is around 15 million degrees celsius. Which is enough heat to reach to are planet earth this day. The sun tends to be a bomb with this much material packed into one star. But yet gravity keeps it together. As time goes the earth will be consumed by the sun. The sun grows bigger and bigger every year. Which will eventually expand to a certain point then earth wouldn't exist.…
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…
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…
A first generation star would be made of mostly lighter materials rather than planets formed later. Since the Universe was originally made up of light elements (Hydrogen and Helium), the planets that would've been formed then would probably be mostly gas giants or planets that lack heavier elements or metals. The planets that are in the process of forming today are most likely going to be made of more heavy elements, since the dust in the nebulae have had time to condense and form heavier atoms…
