The Andromeda is part of the Local Group of galaxies. The Andromeda galaxy is the closest full size galaxy to the Milky Way. The Andromeda Galaxy is about four times bigger than the moon in the sky. Andromeda contains around one trillion stars. The Andromeda Galaxy is also the only galaxy noticeable to the naked eye in the Northern Hemisphere. The Andromeda Galaxy is the Milky Way's larget galactic acquaintance and is on course for a collision in the fututre.
It is believe that the Milky Way Galaxy and the Andromeda Galaxy, also known as M31, will collide in the future. The Andromeda Galaxy keeps moving toward the Milky Way at about 250,000 miles per hour.The Milky Way and Andromeda are moving toward each other under the pull of gravity. At first, the two galaxies may whirl past or through each other, dragging out long gravitational tails. Then the Milkey Way will be distorted out of recognition. But then the gravitational attraction of the galaxies's dark-matter halos will cause them to coalesce. When everything settles down in about one billion years , the combined ex-spirals may have created a large egg shaped galaxy blazing with newborn suns. These new star systems will be rich with heavy elements and shepherd Earthlike plants. Also, the Triangulym may be part of the collision. This collision will take place in about four billion years from now. There is also a very little chance that M33 will come toward Milky Way first and collide too. It will take another two billions years after the collion for both to join into one single galaxy. (space.com 1)

...culiar patches known as nebulae that were inside of them. Heber Curtis spotted multiple stars in Andromeda and argued that it was a separate galaxy. His argument wasn’t concluded until 1925 when Edwin Hubble identified a special kind of star known as a Cepheid variable. A Cepheid variable is a star whose characteristics allow for exact measurements of distance within Andromeda. Since Shapley had previously determined that the Milky Way was only 100,000 light-years across, Edwin Hubble’s calculations reported that the fuzzy patches were too far away to lay within the Milky Way Galaxy.(www.crystalinks.com 1)
In conclusion, the Andromeda Galaxy is a very important galaxy because it effects other galaxys, like the Milky Way Galaxy. The Andromeda Galaxy is coming closer and closer towards the Milky Way Galaxy every second and in the future will collide into one galaxy.

In the book, The Andromeda Strain there is a problem that faces mankind. This problem is a strange virus that comes to Earth from an unmanned satellite, which was in space. This satellite crashes into a small town in Arizona, which has a population of 38 people.
Messier 8, nicknamed the Lagoon Nebula is an interstellar cloud located in Sagittarius, discovered by John Flamsteed in 1680. It is one of the few nebulae that can be seen by the naked eye. It was given its nickname by Agnes

Distances so vast that the light from those areas in space is billion years old. Illingworth was able to see these ancient giants with the Hubble Space Telescope. A telescope that is high above the atmosphere, because it can distort the image. 100 sextillion miles or 17,010,779,502.32 light years is the most distant galaxy Illingworth

Nebula away so that it can avoid certain things. In the short story, “The Star,” the priest stated,
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.
The Orion Nebula is one of the closest stellar regions to the Earth. Using parallax measurements, it has been estimated that this nebula is only 1,500 light years away. In addition, the Orion Nebula is a relatively young star cluster, with an approximate age of less than one million years. It has even been speculated that some of the younger stars within the cluster are only 300,000 years old.
By 1936, astronomers had realized that the hazy balls they sometimes saw in their telescopes, which looked like stars obscured by gas, were actually galaxies (Hibbison).
astounding wonders of the galaxy, but we may never find the answers that we’re looking for.
In modern day physics, Black Holes have dominated the spotlight for quite some time. While the concept has answered many questions, it has also introduced hundreds more. There is believed to be a black hole at the center of our galaxy, the Milky Way galaxy. Black holes were first proven to exist in the 1970’s when a few scientists identified a black hole called Cygnus X-1. Since then, an intense amount of study has been dedicated to discovering the various properties of black holes.
Comparing this galaxy’s size to are own Milky Way Galaxy, which is estimated to be around 8.5*1011 solar masses large, the Andromeda Galaxy is about 20% bigger then are own. Along with this we also know that both our own galaxy and this galaxy are on a collision course. It is estimated that in around 7.5 billion years that these two galaxies will merge together in a surely violent process. It is suspected that after this a large disc or elliptical galaxy will exist in the place of the once separate galaxies.
Astronomers believe that most galaxies consist of a supermassive black hole at the center, which attracts all constituents of galaxies such as, dust, gases (mainly Hydrogen and Helium), atoms, stars, interstellar clouds and planets to the center by force of gravity, but are not sure whether all galaxies contain a black hole in the center. Galaxies keep moving in relative motion to one another and intermittently can come so close that the force of gravitational attraction between the galaxies may become strong enough to cause a change in the shape of the galaxies, while in exceptional cases, the galaxies may collide. If two galaxies collide, they may pass right through without any effect or may merge, forming strands of stars, extending beyond 100,000 light years in space (World Book Online Reference Centre, 2005). Hence, neighboring and often other colliding galaxies induce the sha...
