Nasa Hubble Space Telescope has snapped a spectacular view of a star-forming region in our Milky Way galaxy that looks like a snow angel in deep space. The bipolar star-forming region, called Sharples 2-106 (or S106 for short) is located nearly 2,000 light-years away in the direction of the constellation of Cygnus (The Swan).
A supermassive black hole in the heart of Milky Way galaxy is going to absorb the large cloud of gas
Astronomers have spotted the most jam-packed cluster of young supermassive stars ever seen in the Milky Way galaxy, including hundreds of the most massive types of stars that are dozens of times heavier than our sun.
A team from University of California in Berkeley has found two gigantic black holes in the clusters of elliptic galaxies more than 300 million light years away from us.
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.
Team of scientists found that black holes in the center of galaxies are transformed into super-bright X-ray sources not as a result of collisions with other galaxies, as previously thought, but by internal processes in stellar systems.In the center of many of the large spiral galaxy are hidden supermassive black holes. Their weight in the millions and even billions of times greater then the mass of the Sun.
According to researchers the newborn Universe is likely to rotate and therefore still has a selected axis of rotation. To make such a statement, a group of researchers from the University of Michigan under the direction of physics professor Michael Longo checked, in which direction rotates each of tens of thousands of spiral galaxies, that are photographed during the project Sloan Digital Sky Survey (digital sky survey Alfred P. Sloan Foundation).Investigated galaxies that are from us at a distance of up to 600 million light years. It was found that the galaxy which spiral arms are twisted anticlockwise, there is 7% more than the galaxies with “opposite orientation”.
New observations from the infrared Herschel Space Observatory reveal that an exploding star expelled the equivalent of between 160,000 and 230,000 Earth masses of fresh dust. This enormous quantity suggests that exploding stars, called supernovae, are the answer to the long-standing puzzle of what supplied our early universe with dust.Cosmic dust is made of various elements, such as carbon, oxygen, iron and other atoms heavier than hydrogen and helium.
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.
