translated from Spanish: NASA telescope captures a “smiling Galaxy”

this image, taken with the Wide Field Camera 3 (WFC3) of the Hubble space telescope of the NASA / ESA shows a space full of galaxies of all shapes, colors and sizes, many of which pe rtenecen the cluster of galaxies SDSS J0952 + 3434.

Just below the centre there is a formation of galaxies resembling a smiley face. Two patches of yellow hang over a wide arc of light. The arc-shaped bottom, Galaxy, has the characteristic form of a galaxy that had gravitational lensing: its light has passed near a massive object on road to us, causing distorted and overreach. Hubble captured this image in an effort to understand how the new stars come to life in all the cosmos. WFC3 is able to see distant galaxies with unprecedented resolution, high enough to locate and study the regions of star formation within them.

Stars are born in huge clouds of gas. These massive clouds, or stellar nurseries, they become unstable and begin to collapse under gravity, becoming the seeds that will grow into new stars. Analyzing the brightness, size and the rate of formation of different stellar nurseries, scientists hope to learn more about the processes that can lead to the formation of a newborn star. The study of nurseries in different galaxies will provide information about the formation of stars at different points in time and space in the entire universe. In this note:
