The Most Important Images Taken by Hubble
Hubble Space Telescope has captured the deepest picture of the universe and that declarede the most far & smallest set of galaxies observed by astronomers. This picture was a result of monitoring long-four-months to only a small patch of sky.
These historical images helps the astronomers to well understand the Big Bang and reveal the first galaxies emerged at the end of the so-called "Dark Ages" & it's expected not to obtain any better images than those untill another telescope is put in orbit around the earth.
Very Beautifull Universe
The Hubble Space Telescope is of the space telescopes type, as telescopes are divided into two types; space and ground telescopes. The Hubble space telescope is the first placed telescope in an orbit around the Earth & is designed for monitoring in the area of the visual field and ultraviolet radiation, astronomers have long pointed out the best vision of the universe at all after long suffering from terrestrial telescopes, which a lot of obstacles stands in the way of clarity of their vision, both the earth atmosphere that is full of dust & the deceptive visual effects of Earth's atmosphere that affect the results accuracy.
Empty Wounderful Space
The Milky Way Galaxy is a spiral form galaxy containing between 200 to 400 billion stars, including our sun, its width is about 100 thousand light years & thickness is about 10 thousand light years, we live on the edge of the galaxy within our solar system, which lies two-thirds of the distance to the galaxy center. If you look at the sky at night you may see a part of our galaxy as a package of stars.
The Universe, Captured by Hubble
The milky way galaxy has a spiral form that consists of a central bulge thick surrounded by four arms curled outward and hemmed in the halo of less intense form, we can not see the spiral as our solar system located in one of these arms called the "Orion Arm" or Local Arm.
From our site, the dust clouds obscure the galaxy center completelyin a way that does not give any maps of visual scene except only a limited view to the Galaxy.
