Elliptical galaxy

I had an open-eyed dream, a kind of vision that I would like to share. The image out of focus that I saw took me back to the time when the primitive form of man touched land for his very first time leaving the water kingdom behind. Then a series of images flashed in front of my eyes showing the evolution from the crawling to the standing and all the mutations of the living energy called man. I saw the progression and the improvement of his presence and his demeanor reaching a tall elegant…

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…

The Sun has been known to be an important aspect of life for every living organism on Earth. The Sun is made out of multiple layers and contains a core like Earth. 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…

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…

“Over one year the Sun appears to us on Earth to follow a route through twelve-star constellations we call the Zodiac. If there is this dark star—or whatever it is because at this stage we don't know—coming in, then the evidence points to its current location at the feet of Virgo.” Karl paused to check his supervisor's reaction. “That's where we would see it if we could. It might be a brown dwarf.” Michael raised his eyebrows and frowned. The table gave a threatening creak as he shifted his…

The Hubble 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…

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…

the night sky, little glowing dots are scattered across the night sky. They are known as stars. There are several billion stars in our galaxy, but only a few are seen with the naked eye. Stars are by definition, large exploding balls of gas made up of mostly hydrogen and helium. The two most unstable elements on the periodic table. The largest star in our galaxy is the sun. It’s the largest star and one of the few stars that are going through a star wide nuclear reaction. The reason the sun has…
