The night sky acts like a "time machine", because light moves at a limited speed in the universe and it does not reach us instantaneously from any distant point. In fact, by staring at the stars and galaxies, we are watching their past. For example, when it is said that a galaxy is 13 billion light years away from the earth, it means that it took 13 billion years for the light of this galaxy to reach the observer. In fact, when the light of this distant galaxy was released, neither the earth nor the solar system existed! "Light year" in astronomy is a unit of measurement of distance, it is the distance that light travels in space in one year. I captured this photo on a beautiful sunflower field in an area called Kalposh. In summer, sunflower is cultivated in this area and gives a very beautiful effect to this area. The livelihood of the people of this area is provided through agriculture, especially the cultivation of wheat and sunflower. JPEG image Edition: 1/1 Size 4600 * 3000 px
