Spiral galaxy

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…

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 an old hypothesis that involves moths navigating by maintaining an acute angle to the moon. The moths could mistake the artificial light for the moon so they spiral…

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…

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…

radiation would also have been continuing to move away faster from us that the wavelength from this radiation would have been moved from being visible light to the CMB we see today. One of the major pieces of evidence for the big bang theory is that galaxies appear to be moving away from us at speeds that are relational to their distance. This piece of evidence is known as “Hubble’s Law”, and this phenomenon was discovered in in1929 by Edwin Hubble. His observation supports the expansion of the…
