Elliptical galaxy

are letting astronomers see a peek of a few faint galaxies that could have occurred as far back as 600 million years before the Big Bang. These tiny galaxies could have possibly played a large part in cosmic reionization. Rachel Livermore an astronomer at the University of Texas at Austin says “That when they detected galaxies as faint they did it supports the idea that a lot of little galaxies reionized the early universe and that these galaxies may have played a bigger role in reionization…

The article, “Our Universe could be reborn as a bouncing baby cosmos” by Lisa Grossman suggests that there may be a new theory to how the universe began, that seems to be more accurate than the current theory. This new theory created by Neil Turok and Steffen Gielen is the new Big Bounce model; not to be confused with the older big bounce-big crunch model. This model, unlike all other past contenders, has been able to begin the first steps in an accurate description to how the universe…

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…

the National Academy of Science urged the construction of such an instrument. The report said that a large orbital telescope would make a "dominant contribution to our knowledge of cosmology," by helping scientists study stars, measure distances to galaxies, and investigate the physics behind our universe.” -from http://history.nasa.gov/hubble/ “NASA” For decades, they spent all types of time and money for making this outer space telescope proposed by Spitzer. After the designing, building and…

WHITE DWARF White dwarves (also known as degenerate dwarfs), are stellar remnants mainly composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being…

produces in its entire 9 billion year lifespan. Not a lot was known about hypernovas until 2003 when a massive gamma ray burst reached earth. This was identified as a hypernova and photographed. In 1999 remnants of a hypernova were found in pinwheel galaxy M101. These remains and the events in 2003 helped scientists to begin to understand what a hypernova is and what it does. During a supernova a large star tears off outer layers leaving a new, colder and smaller…

Introduction: Have you ever notice a moth circling street light, porch lights, or car lights? Pointless, right? Well, the moths have a very specific reason for why they circle and spiral lights. In Khristo Boyadzhiev’ paper, he shows that the moths take an equiangular spiral path. Moths navigate by a point light source called transverse orientation. This source being the moon which was developed well before humans’ invention of the light bulb. One reason behind the spiraling happens to come from…

Stars that are formed with different masses are thought to have different properties, such as low mass stars are more likely to turn into dwarf planets and high mass stars are more likely to turn into supernovas. Average stars like the sun usually become white dwarfs and the process of emitting its outer layers carry on until the stellar core is revealed which is known as a white dwarf. White dwarfs have the mass of a star but are the size of our planet which arose various questions along the…

infinite, we aren't sure exactly how big it is because it is still growing. It is home to countless stars, planets, galaxies, and nebulae. Everything is so far apart. For instance, our moon is 238,900 miles away from the Earth. It is about twice as many miles that someone might walk in eighty years, assuming they walk about 7,500 steps every day. The closest galaxy to us is the Andromeda Galaxy, it is approximately 2.9 million light years away. As long as humans have been alive they have…

Galactic cannibalism, Galaxy harassment, Galaxy collision and Satellite interaction are some different kinds of interaction between galaxies. Interacting galaxies, which is the collective term, are in general the circumstance when two or more galaxies gravitational fields interact with each other causing different effects or different levels of disturbance in the gravitational fields depending on things such as size, speed and more. The word collision that both documentaries and scientists have…
