It seems as if the bright blue crescent is emblazoned on the photo of the NASA / ESA Hubble Space Telescope. What is it? Flying saucer? A hint of aliens? No, you just have a galaxy.
However, the thought arises that the shape of this galaxy looks unusual. It's all about gravitational lensing. In the picture, the gravitational influence of a massive cluster of galaxies (SDSS J1110 + 6459) causes space and time to bend and deform, affecting the light path. This cluster is in the lower left corner of the blue bar. There are some more signs of lensing: stripes, drops, curved lines and distorted shapes. The photo also shows a rare and interesting type of galaxy - “jellyfish”. It can be seen near the cluster (a bright blue material stands out). Such galaxies lose gas due to the process of galactic compression. It arises due to the resistance caused by a galaxy moving through space (this causes the gas to separate).
