Galaxy

The above image was posted on April 28, 2016 as NASA’s image of the day. This is a dust angel nebula. A nebula is a cloud of dust and gas that is visible when light reflects off of it. This nebula is about 300 light-years away from our galaxy, and is a collection of cosmic dust clouds. The nebula gets the cloud-like display from light projected from the Milky Way which is then bounced off of the molecular clouds, where the dust releases UV radiation as a red light/orange light (Space, 2013). The

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

solar system? a. The Sun is a fairly ordinary but large star. b. The Sun is the focal point of our solar system, because all of the planets orbit the Sun. 2) What is our Milky Way galaxy and the sun’s position in it? a. The Milky Way galaxy is where our solar system is located in the universe. b. The Milky Way galaxy is home to over 100 billion stars and the Sun is one of those stars. 3) What is the Big Bang and what does it say about the age of the universe? a. The Big Bang is when the

things, the Milky Way galaxy is just a microscopic portion of one single galaxy in the universe. The Sun that the Earth rotates around is one out of hundreds of billions of stars in out galaxy alone, and more than that our galaxy is but one of around 50 billion to 1 trillion galaxies, and that is just in the known universe. Nearby stars are separated from the Earth by light years, and relatively close by galaxies are so much father away even than that, with the most distant galaxies from our planet being

This difference can be explained due to the fact that some of the Data collected for the graph

Mayall’s object (also known as Arp 148) is the stunning result of an encounter between two galaxies resulting in a ring-shaped galaxy and a long-tailed companion, located almost 465 million light-years away within the constellation Ursa Major. The pair extends across 80 thousand light-years. The collision between the two parent galaxies produced a shockwave effect that first drew matter into the center and then caused it to propagate outwards in a ring. The elongated companion perpendicular to the

collisions or interactions between galaxies are often observed and can be predicted too. This colossal phenomenon occurs due to the large gravitational fields of the galaxies which attract other galaxies or are attracted by the fields of the other galaxies. The force of gravity is exerted when two galaxies are extremely close to each other. Near misses and crashes between any two galaxies are generally referred to as “interactions”. Collision may lead to merging and the galaxies may also bend out of shape

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

Black holes, complex and difficult to understand, have intrigued both scientists and physicists alike since the eighteenth century. French scientist Pierre-Simon Laplace, born in 1749, was one of the first scientists to argue for the existence of an unexplainable body that encompasses an endless amount of space . Following Laplace, John Archibald Wheeler, an American physicist born in 1911, coined the term “black hole” for a space entity that is “so compact (in other words, has enough mass in a small

Did you know that we have a Dark Matter in the Galaxy? The world we see and are familiar with comprises of Ordinary Matter. Everything made out of particles is viewed as Ordinary Matter. Typical Matter makes up of five percent of all matter. So what makes up whatever is left of the ninety-five percent? Dark energy makes up approximately seventy percent of our universe while Dark Matter makes up the last a quarter century. What is Dark Matter? Dark Matter is the main clarification we have for why
