However, unlike other spiral galaxies found scattered throughout the universe, the black hole which is assumed to exist in the center of the Milky Way galaxy is dormant and is not "actively feeding," meaning that it is not currently swallowing up material for some unknown reason. Almost from the beginning of astronomical observations of galactic bodies in the universe, it has always been thought that "the more massive the bulge, the more massive the black hole" which has led scientists and astronomers to reason that "somehow the formation and growth of galaxy bulges and their central black holes are intimately connected." But in 2003 when the Spitzer Space Telescope began to be utilized to collect infrared data from a number of different types of galaxies, scientists discovered that thin or slender galaxies which lack prominent central bulges did indeed contain supermassive black holes.
During a recent study with the Spitzer Space Telescope,...
Thus, as Satyapal sums it up, dark matter "might somehow determine the mass of a black hole early on in the development of a galaxy" which opens the possibility that galactic bulges serve "as a proxy for the dark matter mass, the real determining factor behind the existence and mass of a black hole" in the center of even thin and slender galaxies in the universe.

The diameters of these clusters range from about 75 light years to as much as 400 light years and can be as far as 300,000 light years from the Earth. In many parts of the Milky Way galaxy, there exist dense concentrations of interstellar matter known as nebula and are generally classified as emission nebula, reflection nebula or dark nebula. Emission nebula are by far the most exotic, for they
Milky Way Galaxy is of particular interest to the planet Earth, and the people that reside there, because the planet is one of, possibly, billions contained within it. The term galaxy is used when a large group of stars, generally a billion or more, have clustered together due to a similar attraction to some gravitational attraction. The Milky Way Galaxy is actually a conglomeration of others such as the Canis
There must be an invisible force that is acting on those galaxies. These two features make the accelerating universe the most probable explanation amongst its competitors (Riess 2012). Major surface features of a) the Earth's Moon The moon's major surface features are craters, rays formed through the crashing of meteorites into the moon's surface. There are also Marias and mountains. Marias is a dark hole like features of the moon and
The age of the universe A good way of estimating the age of the universe is dating the oldest objects in the Milky Way Galaxy. Being that the age of the universe varies directly with the Hubble constant, the cosmological constant and the average density of the universe, the direct estimate of the age of the universe can be used to define cosmological models. The metal-poor stars found within the spherical
The materials that are collected in them are solids from the various gases (which cooled inside these clouds). The gravity from the sun pulled them closer towards each other. This contributed to the formation of the planets and asteroids. ("Summary," 2007) (Williams, 2010) Once a star is finished developing, is when solar winds will blow rock and debris away from the sun. This forms the Kuiper Belt and Oort Clouds,
Electromagnetic waves are energy waves produced by the oscillation or acceleration of an electric charge. They include radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Their wavelengths in meters are: radio waves (0.1 to 1000), microwaves (1 x 10-3 ~ 1 x 10-1); infrared (7 x 10-7 ~1 x 10-3); visible light (4 x 10-7 ~ 7 x 10-7); ultraviolet rays (1 x 10-8 ~
