Andromeda Galaxy

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…

Stars are complex and giant balls of matter that have many things to understand about. Stars are born of gas and dust and have a life cycle based on their original mass. All stars start out in their main sequence, but the first difference between the mass of stars is when they stop producing energy. The low-mass stars become giant, and the high-mass stars become super giant. For low-mass, the star then becomes a planetary nebula, then finally a white dwarf. High-mass stars become a supernova, a…

Geography Question 1: The big bounce theory. The big bounce theory is a theory that scientists have created that shows that the universe was formed The big bounce theory is a scientific theory about the origins of the universe. Scientists say that our universe is the result of the previous universes collapse. The big bounce theory states that the universe expands and contracts. The universe expanded so greatly that it exploded and created the universe we’re living in today, The Milky Way.…

Analysis The Earth and the Universe: First of all, Hesiod’s Theogony (circa. 700 BC) is a written source explaining the connections between the gods, goddesses and these immortal beings are the embodiment respective parts of the earth and universe. Hesiod explains that in the beginning there was only Chaos and then came Gaea, the broad earth who supports Mt Olympus and at its core, Tartarus. From Gaea came Uranus, the sky and stars and together they bore the titans and titanesses and the…

The cosmos are a timeless collection of space and stars. It’s our home and it’s our Earth’s home. It holds the key to our survival, the sun. It it both where we came from and where we are going. The universe is all that we have, and human kind has developed the ability to explore it. But the real question is if we should. Some issues should be considered when it comes to space exploration, and those are economics, ethics, and science. These three things are the most important factors to consider…
