Astronomers have assembled one of the most comprehensive view yet of the early universe.

Taking advantage of the unparalleled sharpness of Hubble Space Telescope, astronomers have captured a large panoramic view of the distant universe. The busy image features approximately 15,000 galaxies and most of these are star-forming. Those galaxies formed their stars billions of years ago, early in the history of the universe or about 3 million years after the Big Bang.

How star form is still an intriguing question. Thanks to ultraviolet data from NASA's Hubble telescope, astronomers can get a closer look at which galaxies are forming stars. By observing the extreme environments of these galaxies, they can learn not only about the evolution and the history of the universe but most importantly about the fundamental processes of star formation. Hubble data could help researchers fully understand how, when, and where star formation occurs and how these stars change over time.

“Ultraviolet light has been the missing piece to the cosmic puzzle. Now, combined with infrared and visible-light data from Hubble and other space and ground-based telescopes, astronomers have assembled one of the most comprehensive portraits yet of the universe's evolutionary history.” NASA statement said.

Stars are formed inside the clouds of dust and gas located in most galaxies. As clouds of gas clump together and collapse, they form the structures or hot cores from which stars are born. These structures gather dust and gas, eventually giving rise to a cluster of young stars of various masses. But researchers still don't understand many aspects of how stars form.

They need ultraviolet light to understand the complexities of star formation and to get a complete stellar history. But much of the light from star-forming regions in distant galaxies is no longer visible due to the expansion of the universe. As the Earth's atmosphere filters most ultraviolet light, this task can only be achieved with a space-based telescope like Hubble. Hubble telescope provides some of the most sensitive ultraviolet observations possible in space.
