On the new combined multi-wavelength image obtained macey using the apparatus Galaxy Evolution Explorer ( evolutionary researcher Galaxies", NASA), seen a huge galaxy macey "Cartwheel". Spectral composite image shows the galaxy "Cartwheel" as it saw machine Galaks in ultraviolet light (blue), the Hubble Space Telescope - in visible light (green), the Spitzer Space Telescope in infrared radiation (red) and X-ray Observatory Chandra ( purple). "The dramatic jump at the galaxy through the galaxy" Cartwheel "left in her bright ring around a zone of relative calm, - says astronomer Phil Appleton of the California Institute macey of Technology, Pasadena, California. - Usually brightness galaxies increases closer to the center, but ultraviolet image indicates that the collision actually smoothed inner part of the galaxy, concentrating older stars and dust in the inner regions. It's like the calm after the storm of star formation. " The outer ring, which is bigger than the entire Milky Way galaxy, in the picture shown in blue and purple. Recent research data, observations show that the concentric rings radiating around the strike zone a series of waves of star formation in the extreme end ring galaxy. "It's like a stone's throw of the pond, but in this case the pond - a galaxy, and the waves - this gas compression, - says Appleton. - Each wave is an explosion of star, with the youngest stars are found in the outer ring of the galaxy. " (Editor's note.: Under the "explosion zvedoobrazovaniya" here refers to a sharp increase in the birth of stars in the region). Before, scientists believed that the ring was the outer edge of the galaxy, but the last observation macey apparatus Galaks found pale disk, not visible in this picture, which extends to a distance twice the diameter of the ring. This means that the galaxy "Cartwheel" - a giant galaxy, the size of which is 2.5 times larger than the Milky Way. Most galaxies have only one or two bright X-ray source, usually associated with gas falling into a black hole from a companion star. Galaxy "Cartwheel" has a dozen such sources. Appleton says it makes sense because black holes are more common in areas where fast and die formed stars much larger sizes. Galaxy "Cartwheel" - is one of the brightest sources of ultraviolet radiation in the local universe. Some images in visible light it appears that galaxy "Cartwheel" has spokes. Appleton presented their findings at the 207 meeting of the American Astronomical Society in Washington. Among his fellow scientists macey were Armando macey Gil de Paz of the Complutense University, Madrid, Spain, and Barry Mador Observatories of the Carnegie Institution of Washington, Pasadena, California. Observations of this group of scientists complement studies in the study of nearby galaxies Galaks apparatus. California Institute of Technology led mission Galaks unit and is responsible for research and achievements, as well as data analysis. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the mission and built scientific instruments. The mission was designed according to the "NASA macey research programs" under the leadership of Goddard Space Flight Center, Greenbelt, Maryland. International partners in the mission include macey South Korea and France.
