Sombrero Galaxy

What are Galaxies? You have probably heard about galaxies, whether it was in school, a book, a television show, or movie, you've most likely heard about them. If you're wondering, "what exactly are galaxies?" fret not, friend, for I will help you figure out this question. Let's start with some history. In 5th century, BC, someone named Democritus had the idea that the bright band in the sky(known as the Milky Way) may be composed of stars. In 4th century BC, Aristotle had the similar idea: "the

of humanities dawning intellect, it was a mere accident. The scientific community had no inkling that the universe was made up of more than what we can see until the 1930’s. A Swiss astronomer—Fritz Zwicky—was measuring the speed of the orbits of galaxies in the Coma Cluster (Ferris). His calculations indicated that the

Theory of Relativity that relates to space, time and gravity. Willem de Sitter, Aleksandr Friedmann and Georges Lemaitre later applied Theory of Relativity to the Universe and confirmed that the Universe could be expanding. Vesto Slipher observed that galaxies were moving from us than approaching us. Edwin Hubble discovered that universe was smaller in the past and has been expanding. The Big Bang Theory states that the universe began by expanding from a small volume to a large volume with high density

How the Big Bang Evolved into Life On Earth Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started. The beginning of time and the universe began with the Big Bang. This was an explosion that started the expansion of the universe. In the most basic sense, the standard model is simply the idea that every bit of the matter and energy in the universe was once

Significant Discoveries Funding was approved in 1977 for a Large Space Telescope in 1977 and in 1983 it was renamed Hubble Space Telescope in honor of astronomer Edwin P. Hubble who discovered evidence of an expanding universe and the existence of other galaxies. Work was completed in 1985 and it was launched and deployed from the Space Shuttle Discovery in April of 1990, 350 miles above earth. Since its deployment, there have been five services, each service to perform corrective and preventive maintenance

in the universe. David Sobral and his team at the University of Lisbon led the work in finding this cluster of stars in a bright galaxy, named COSMOS Redshift 7 (CR7). The team at the University of Lisbon used the Subaru Telescope in Hawaii to first detect the light spectrum from CR7, and used three additional telescopes to determine which of the distant bright galaxies the light originated. The Subaru Telescope is located in Mauna Kea, Hawaii, and is an 8.2 metre optical-infrared telescope, operated

Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing. According to the Big Bang Theory the universe appeared as a singularity. Singularities are thought to exist at the core of black holes. These zones of infinite density are called "singularities." Our universe is thought to have begun extremely small, infinitely hot, and infinitely dense. As time

Voids are the spaces between filaments and are rare because most galaxies exist around voids in sheets or filaments. Most void galaxies scattered throughout the universe. They are are connected by relatively direct void filaments usually 11 to 150 megaparsecs in diameter and which are lighter versions of the typical galaxy can be defined by the absence of galaxies. They filaments that surround voids. These galaxies are theorized to have formed from mass are theorized to have formed from pure

unusual bending of light in places where nothing but empty space exists as well as the unusual movement of stars and galaxies that can not be accounted for. The dark matter problem arose because of a difference in the masses of galaxies and larger cosmic structures. The components of these systems-stars and gas is in the description of galaxies. Gas and galaxies in the case of galaxy clusters move about but do not escape. They are restricted because they are watched over carefully by the gravitational

Zodiac constellations and one of the original 48 listed by the ancient Greek astronomer Ptolemy. Its name is Latin for crab and its astrological symbol is ♋, which represents crab pincers. This constellation attracted my interest because it contains a galaxy with a binary supermassive black hole system: OJ 287. -The constellation of Cancer as it can be seen in the sky. In the mythology of The Twelve Labours of Heracles (or Hercules in Roman mythology) Cancer is a crab sent by Hera to hinder Heracles
