The research team of astronomers from the University of Tokyo and the National Society of Astronomers of Japan (NAOJ) have discovered the location of red galaxies in galaxy clusters, presumably located in the 4 billion light years from Earth
As we know the current models explain elliptical galaxies as dead galaxies, but have to say a completely different history is suggested by the images of two galaxies obtained by the MégaCam camera of the Canada-France-Hawaii Telescope (CFHT, CNRS/CNRC/University of Hawaii). All members of an international Atlas3D team, have shown that these two elliptical galaxies were formed from the merger of two large spiral galaxies, just 1 to 3 billion years ago.
According to astronomers dwarf galaxy a satellite of the Milky Way, Segue 1, retained the title of “Center of darkness” of the Universe,the largest known concentrations of the mysterious dark matter. Astronomers measured the velocity of the stars relative to the Milky Way and each other.
The European Southern Observatory released the new image on July 27, 2011. It was taken by the observatory’s VLT Survey Telescope and shows three interacting galaxies located in the constellation of Leo, which is about 35 million light-years away from Earth.
NASA’s Chandra X-ray Observatory for the first time captured powerful stream of gas rushes to the massive black hole. The observations will help tackle two of the most fundamental problems in modern astrophysics: understanding how black holes grow and how matter behaves in their intense gravity. The black hole is at the center of a large galaxy known as NGC 3115, which is located about 32 million light years from Earth. As gas flows toward a black hole, it becomes squeezed, making it hotter and brighter.
Black holes are rarely in a quiet condition. They not only rotate but can move up and down of the home galaxy. Researchers from Brigham Young University conducted a study of this movement and came to the conclusion that both types of motion of black holes provided with energy one of the brightest objects in the Universe, such as quasars
The nebula is around the star cluster NGC 1929, which lies within the Large Magellanic Cloud, a small satellite galaxy of our own Milky Way. The image that show one such region, which surrounds the star cluster NGC 1929, was taken by using the European Southern Observatory’s Very LargeTelescope, located at the Paranal Observatory in Chile’s Atacama Desert.The NGC 1929 star cluster contains hot young stars that are emitting intense ultraviolet light and causing the gas to glow.
New observations from the Herschel Space Observatory show a fantastic, twisted ring of dense gas at the center of our Milky Way galaxy. Alberto Noriega-Crespo of NASA’s Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena say that they have looked at this region at the center of the Milky Way many times before in the infrared, but when they looked at the high-resolution images using Herschel’s sub-millimeter wavelengths, the presence of a ring is quite clear.
Scientists have known that the masses of the largest bodies in the Universe depend on the method in which this mass is measured.Measurements of the galaxy cluster are carried out in three different regions of the electromagnetic spectrum: X-ray, optical and millimeter wavelengths, which leads to different results.
Eduardo Roseau at University of Chicago, explained that the performance of any two measurement methods may be virtually identical, but the third way will be radically different.
