A shot from the Hubble Space Telescope wide-angle camera 3 demonstrates a huge gravity effect. More specifically, this is a gravitational lensing caused by an SDSS object J1152 + 3313. The data obtained in the research program on the formation of stars in old and distant galaxies.
Gravitational lenses, like this galactic cluster, are endowed with large masses. They bend light from distant objects into rings, arcs, streaks, blur and other fuzzy shapes. But this lens not only envelops the appearance of a distant galaxy, but also enhances its light, making it brighter. Combined with high quality imagery, this provides valuable clues about how stars are born in the early Universe. Star birth is a key process in astronomy. Everything that emits light is somehow connected to the stars. Therefore, an understanding of the process of their appearance will help to understand the countless space objects. Scientists can study these early areas of star formation to learn about the sizes, luminosities, speeds, and generations of different stellar types.
