We should now be able to account for that motion."įor example, one structure revealed for the first time in the new map is likely to exert a gravitational tug on the Milky Way and could be part of the solution, the researchers said. Only by making an all-sky map can you account for all the galaxies that are there. "What's causing that is gravity, and finding the source of that gravity, where the mass is, has been a longstanding issue. "The most important science question that having a complete map addresses is the source of the motion of the Milky Way," Masters said. This motion, about 370 miles per second (600 km per second) has yet to be explained by the gravitational attraction of the known objects near our galaxy. An international consortium of scientists has completed a joint survey of the cosmos analysing several million galaxies and quasars to create the largest 3D map of the Universe. In addition to providing a more complete picture of our place in the universe, the new map could help solve the perplexing mystery of why the Milky Way moves the way it does with respect to the rest of the universe. celestial objects celestial vault astronomy WinStars 3d map Franck. This happens because of the so-called Doppler effect, which causes the wavelength of light to be stretched when the light's source is moving away from us.īecause the universe is expanding, measuring an object's redshift, and hence its velocity, allows astronomers to deduce its distance, because objects that are farther away are moving more quickly. Who has not been dazzled and intrigued when lifting his gaze to the celestial vault on. The orbits of the planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune Light travel time from Earth: 1 hour Our solar system. Quasars are in red and nearer galaxies in yellow. The 3-D aspect of the map comes from the fact that researchers measured the cosmic objects' redshift, which denotes how much its light has been shifted toward the red end of the color spectrum. A slice through the largest 3-D map of the universe to date. Masters presented the new map here today at the 218th meeting of the American Astronomical Society. "In the infrared, we're less affected by the gunk in the milky way so we're able to see down closer to the plane of the galaxy." ![]() "This covers 95 percent of the sky," Masters said. This allowed the 2MRS survey to extend its "eyes" closer to the plane of the Milky Way galaxy than has been possible in previous studies, because that area is heavily obscured by dust. Near-infrared light, which is of a longer wavelength than visible light, can penetrate the opaque clouds of dust common in galaxies. ![]()
