Whereby, strictly speaking, we are not looking directly into the center, but rather at the imposing stardust clouds that cover the center. This explains why the summer milk route is much brighter and more pronounced. (Wallpaper: NASA / JPL-Caltechâ €? - Schemes: Own illustration) The picture on the right illustrates this schematically. At the zenith we have year-round Andromeda and the Hercules faithful companions.ĭuring summer, b ecause of the position towards the sun and the tendency to earth, we look into the center of our Milky Way, while in the winter we look into the side branch of the Milky Way, "out" into space. In the summer, we can admire many clusters of galaxies (such as the Lion or the Virgin), while in winter we can admire the well-known Orion Nebula. On the journey of our earth around the sun, which is known to last a year, not only change the seasons, but also the direction in and out of our Milky Way.Īnd so the sky and its visible objects are different, depending on the season. If you do not believe that, you can read it at DLR: here -) If we take the speed of the solar system around the center of the Milky Way, we move to this center at a rapid 790,000 km / h through space. Often we forget that our Earth itself is a spaceship that moves around the sun at about 107,208 km / h (average value). Astronomy is a hobby for the whole year- because with the seasons the sky constellations changes as well. ![]()
