Fourth of a million galaxies can be seen in the stunning panorama of Hubble’s footage

This Hubble Space Telescope image represents the largest, most comprehensive "history book" of galaxies in the universe.The image, a combination of nearly 7,500 separate Hubble exposures, represents 16 years' worth of observations.The ambitious endeavor, called the Hubble Legacy Field, includes several Hubble deep-field surveys, including the eXtreme Deep Field (XDF), the deepest view of the universe. The wavelength range stretches from ultraviolet to near-infrared light, capturing all the features of galaxy assembly over time.The image mosaic presents a wide portrait of the distant universe and contains roughly 265,000 galaxies. They stretch back through 13.3 billion years of time to just 500 million years after the universe's birth in the big bang. The tiny, faint, most distant galaxies in the image are similar to the seedling villages from which today's great galaxy star-cities grew. The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see.The wider view contains 100 times as many galaxies as in the Hubble Ultra Deep Field, taken in 2004. The new portrait, a mosaic of multiple snapshots, covers almost the width of the full Moon. Lying in this region is the XDF, which penetrated deeper into space than this legacy field view. However, the XDF field covers less than one-tenth of the full Moon's diameter.

Fourth of a million galaxies can be seen on the stunning panoramic image of Hubble Space Telescope. The researchers put together a single picture of the 7500 recordings of Hubble’s 265,000 galaxies. The picture contains observations of 16 years. Some of the galaxies are so far away that their light has been on the planet for over 13 billion years. So they can be seen from the age when space was only 0.5 billion years old. Thus, the panorama image shows the history of galaxy formation up to the present day.

Garth Illingworth, a researcher at the University of California, head of the panoramic image team, said that much more distant galaxies could be mapped than in the largest data collection ever.

“No image will surpass it until the new space telescopes, including James Webb, start working,” the expert said.

The panoramic image was named Hubble Legacy Field, referring to three earlier projects in which the space telescope looked further away in the cosmos. The farther the astronomers can see in space, the more they can discover the cosmic past. Before the Hubble began in 1990, terrestrial telescopes were able to capture galaxies at a distance of up to seven billion light-years away, halfway to the big bang, said the Information Center.
