Telescope "Hubble" fixed spiral galaxy


01/10/2012

The orbital telescope "Hubble" took a picture of the spiral galaxy NGC 4183, located in the constellation Canes Venatici. The resulting image, along with a description were published on the official website of the European Space Agency.

The galaxy NGC 4183 is a spiral galaxy in size, a little smaller than the Milky Way. Its diameter is about 80,000 light years. This galaxy is in a group of moving stars of Ursa Major and removed at 55 million light years from Earth.

In the picture clearly shows a huge amount of interstellar dust contained in the galaxy. Clouds of dust obscured the light of distant stars in the photo looks like a network of dark filamentary structures - filaments.

NGC 4183 is located in relation to the earth at a sharp angle, which does not allow a good look at the image of its structure. In the center of the galaxy is much less substance than on the periphery, so the process of star formation there is much slower. However, as shown by the data of astronomers from the periphery to the center of the galaxy extend bridges by which the transfer is carried out and the necessary material.

Image of NGC 4183 was obtained by the established in 2002 on the "Hubble" camera ACS, in the visible and infrared range. Meanwhile, the telescope itself was in orbit in 1990. It is planned that in the future, "Hubble" is to change the orbit of James Webb telescope, equipped with a mirror is much larger (6.5 vs. 2.4 meters) and more modern scientific techniques.
