The photograph shows the system of gravitational lensing SDSS J0928 + 2031. Recently, more and more of these images appear, as now the Hubble Space Telescope is actively used to study the birth and evolution of stars in distant galaxies.
Gravitational lensing helps astronomers investigate objects that appear to be weak or too small in ordinary observations. When a massive object, like a cluster of galaxies, distorts space with a giant gravitational field, it causes light from distant galaxies to move along curved paths. In fact, here the galactic cluster plays the role of a magnifying glass, which allows studying the objects behind it.
In the photo you can see two dominant elliptical galaxies near the center. The effect of lensing is immediately noticeable due to the presence of narrow and curved bands of light surrounding both large galaxies.
