Hubble photographed 15 thousand distant galaxies

Using the ability of the Hubble telescope to make images in the ultraviolet part of the spectrum, astronomers were able to get one of the most large-scale panoramic images of the early universe. On it you can see a portion of the sky in the direction of the constellation Ursa Major. The area of ​​the captured region is 14 times the area of ​​the famous Hubble Ultra Deep Field image.

Almost every bright dot in the new Hubble image is a different galaxy. In total, the telescope was able to photograph almost 15 thousand galaxies. In 12 thousand of them are active star formation processes.
Such Hubble images allow astronomers to close a kind of observational “gap”. The fact is that areas of active star formation emit ultraviolet radiation. But due to the red shift effect, the ultraviolet light of the most distant galaxies turns into infrared.

By combining images made by Hubble in infrared, ultraviolet and visible light, astronomers can, figuratively speaking, cover the whole picture. Studying the properties of star-forming regions in the distant and nearby Universe allows us to better understand how galaxies could grow from relatively small clusters of hot young stars to huge structures.
