| 释义 | 星系 “There is an observational correlation between the mass of the black hole and the mass of the dark matter halo, not necessarily the mass of the galaxy itself, ” she said. But some of the most beautiful things in nature and our universe exhibit mathematical properties, from the smallest seashell to the biggest whirlpool galaxies. As we move out, the light from these distant galaxies have taken so long, we're essentially backing up into the past. Instead, she found that all stars in a galaxy seem to circle the center at roughly the same speed. Anyone interesting on that side of the galaxy? Mergers cause gases to flow towards the galactic center, which can trigger phenomena like rapid star formation. Massive objects like the sun can bend light, but colossal clouds of dark matter create“ bubbles” in the cosmos that magnify, distort and duplicate the light of galaxies or stars behind them. The distortion of the galaxy on the far right, however, is an illusion. Now, an international team of astronomers claims to have solved the mystery of how legions of these galactic monsters were born during the early history of the universe. Almost every object in the above photograph is a galaxy. To start, almost every fuzzy yellow patch in the above image is an entire galaxy. Residual sunlight from a sun already set lit the horizon and clouds while the stars and Milky Way galaxy revealed themselves up above. I think it is still unclear whether black holes play any role in the formation of the first galaxies. We all know what a galaxy is, right? Our Milky Way, if it could be viewed edge on, would display a good example of one of these galactic bulges: Imagine the profile of a stereotypical flying saucer, though with a wider and flatter disk. A team of U.S. and European researchers using the Hubble Space Telescope have captured infrared images of a blurry object they believe to be the oldest galaxy ever seen by man. An active galaxy is a star system with a humongous black hole at its centre. At times, enough gas builds up for the dwarf to collapse, leading its carbon to fuse nearly instantly and the dwarf to explode in a Type I supernova, which can outshine a galaxy for a few months. It is a galaxy of knowledge and information. Is this one galaxy or two? The reason is that galaxies do not behave in the way that they should if the laws of gravity are correct. This band is the disk of our spiral galaxy. The galaxy looks so good because it lies behind a galaxy cluster. These results help explain how a supermassive black hole can alter the evolution of its host galaxy. As you can see, the galaxy has more than one nucleus! Pretty sparse, but enough to start the seeds of light and life in the galaxy. |
