This photo from the NASA and ESA space telescope camera WFC3 shows the Hubble area of space filled with galaxies of various shapes, colors and sizes. WFC3 is able to view many of these formations in unprecedented resolution — high enough to find and study areas of stellar birth.
Stars appear in large gas clouds. These massive clouds (star nurseries) lose stability and begin to collapse under the action of gravity. Thus, they are transformed into future stars. By analyzing the luminosity, size and speed of appearance of different star hospitals, scientists hope to learn more about the processes leading to the birth of a star. The formation of galaxies resembling a smiling face is shown just below the center of the frame! Two yellow drops hang over a huge arc of light, creating a celestial object SDSSJ0952 + 3434. The lower arc-shaped galaxy is an example of a gravitational lens - its light passed near a massive object en route to us, because of which the shape became distorted and stretched.
