A photo from open sources
In a new photograph taken with a space telescope Hubble, among the galaxy cluster SDSS J1038 + 4849 is drawn smiling face created by the light of the universe. Two bright dots reminiscent of the eyes, a nose looms from a cluster of stars, and curved lines of light create a line of a smile and the contours of an oval face. ВIn general, looking at the image, it seems that in the photo captured a smiling, happy face of the universe located in a cluster of distant galaxies. In fact, the “eyes of the universe” are light from the stars of distant galaxies, and the curved lines of her face appeared as a result of the action of gravity around their clusters. This effect known as a gravitational lens. Theory of General Relativity Einstein says that massive objects can bend the space surrounding them in such a way that passing through this space light can not only be redirected, it can also be amplified or distorted, as if it were passing through a powerful lens. Clustered galaxy clusters are one of the most massive objects in our visible Universe so it can create powerful gravitational effects lensing. Moreover, in the case of the space “smile” the cluster of these galaxies, as well as distant light sources, are ideal aligned with the Hubble telescope in a straight line. As a result of the hubble fixed the so-called Einstein ring, in which the light from a more distant object is blurred in a circular path. It is this effect that creates the lines of the “smile”, as well as the lines of the outline “faces of the universe.” Astronomers often look for signs of gravitational lensing in order to identify massive objects, including black holes, galaxies, and even dark matter.
