... spin of black holes, understanding the physical conditions in sites of cosmic-ray acceleration, and the distribution of dark matter in galaxy clusters. To achieve these objectives, Astro-H will make use of a Soft X-ray Spectrometer (SXS), a device...
... percent of the mass of all the stars in the galaxy," explained Barth. "Most of a galaxy's mass is in the form of dark matter and stars, and on the scale of an entire galaxy, even a giant black hole is just a tiny speck in the...
... mass range has not been determined Some scientists think that axions could explain the mystery of dark matter, but another interesting property of these ultra-low-mass particles is that they can convert into a photon...
... to wait until telescopes such as the Vera C. Rubin Observatory come on line. Aside from helping to search for dark matter by mapping galaxies through time and space, the Rubin Observatory also aims to catalog 90 percent of the near...
... black hole, and only 0.1 percent could include stars, smaller black holes, interstellar dust and gas, or dark matter. Located roughly 27,000 light-years from the Sun, the centre of our galaxy is dominated by a supermassive black...
... features of the Chinese facility, Wu said, is that it will be visited by a large-aperture astronomy telescope, designed to study dark matter, which will be able to dock at the space station for maintenance and hardware upgrades. The future Chinese...
