Andromeda Galaxy

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…

First, Energy has multiple forms that can switch different states. The two most common forms of energy are, Kinetic and Potential Energy. Kinetic Energy is the energy created when an object is in motion. It can be transferred between two objects if the object has enough energy, therefor it can be from of a collision. Kinetic energy can also be elastic or inelastic energy, however Potential Energy is an energy, but is potentially created before Kinetic Energy. Both types of energy are measured in…

figure out what it is, but no one truly knows what composes dark matter. Physicists are so interested in understanding dark matter because it accounts for the formation of the Universe, as observable through studying the distribution of gravity within galaxies (Carnegie). Original attempts at studying dark matter referred to dark matter as baryonic, which is a word used to describe baryons, or quark based particles. Quarks make up “normal” subatomic particles, and so when referring to dark…

Statement: Body: The Drake Equation’s general expression is N = R* fp ne fl fi fc L. N represents the number of communicating intelligent civilizations within the universe right now. R* is the approximate rate of the formation of stars within our galaxy. Fp represents the fraction of stars in the Milky Way that are companioned by other planets. Ne takes the place of the number of planets per sun-like star that have habitable ecospheres, which is what allows for the chemical evolution of…

Many scientists, starting with Galileo, had noticed there was something strange because of a small fleck they saw in the sky. These scientists had try to discover something new, but each time, their ideas were dismissed. This went on for several years, before William Herschel had the motivation to figure it out for himself. At first, he thought it was a comet, but through a mirror he had built, was able to verify that this object wasn’t making the same motion as a comet would. This is where his…

Theory on Lithium in Stars May Be Confirmed The light chemical element lithium is one of the few elements that is predicted to have been created by the Big Bang, 13.8 billion years ago. But understanding the amounts of lithium observed in stars around us today in the Universe has given astronomers headaches. Most heavy elements are produced during supernovae, as massive stars explode in their death throes. However, these events were believed to be too rare to produce the vast amount of…

Fixtures of the northern sky, the Big and Little Dippers, swing around the North Star, Polaris, once a day or once every 23 hours and 56 minutes. Polaris marks the north celestial pole around which all the stars of the northern sky appears to rotate. It also marks the end of the Little Dipper’s handle and the whole constellation (Ursa Minor) is circumpolar, which means it’s always above the horizon in northern latitudes to as far south as the tropic of Cancer (23.5 degrees north latitude). The…

It essentially started the motion of the rearrangement of the kosmos into the way it is today. The way we see the galaxy right now, was because of nous all those years back. It acted as an energy of sorts that helped create the kosmos and is still very much present in modern times today. Therefore, I absolutely agree with what Anaxagoras said about nous and how it’s…

These live shorter than most other stars in the galaxy. The Planetary Nebula is consisting of glowing shell of gas, and plasma formed. Some of these exist in the Milky Way Galaxy. This is an important star because they play a key role in the chemical evolution. Massive Star : Any star that is larger than eight solar masses is a massive star. Massive stars are formed…

of times larger than our sun. They are believed to be at the center of almost every galaxy, including our own. They are easily detected from their effects on nearby stars and gas, unlike most stellar black holes that are rarely found. Based on the amount of stars that are eligible to become a stellar black hole, scientists can estimate that there are as many as ten million to one billion black holes in our galaxy alone. The stellar black holes are a lot more common because it is easier for them…
