NASA's Hubble Space Telescope has been peering into the unknown universe for nearly 30 years. Since its inception in 1990, Hubble has consistently provided iconic images of the universe, allowing us to better understand infinite space. And NASA's eyes in the sky revealed their most incredible image to date, with the release of the deepest image of the universe ever taken.

Astronomers have used a revolutionary new technique to reveal the "lost" light in Hubble Ultra-Deep Field (HUDF) images.
The HUDF is an image of a small area of space in the Consacus constellation, believed to contain about 1
Researchers at the Canary Islands Astrophysics Institute (IAC) have processed a set of several images of Hubble to reveal a revised image of the universe. MARCH MARS: NASA Investigates a Strange Stroke Crater on a Red Planet
By processing and combining several images during the three years of project completion, the researchers discovered a certain amount light from the outer zones of larger galaxies.
The MAK researchers said: "The restoration of this light emanating from the stars in these outer zones is equivalent to the restoration of light from a complete galaxy.
This missing light now shows that some galaxies have diameters nearly doubled, as previously thought.
Alejandro Borlaf, head of the IAC team project, said: "What we did was return to the archive of the original images. , directly observed by Hubble, and improved combination process. Ultima Thule in HD: NASA releases a new photograph of "Space Snowman" 4 billion miles
"Our goal was to achieve the best quality of the image not only of the more distant smaller galaxies but also of the elongated regions of the largest galaxies
"The image of the universe, which is now deepest, is possible thanks to a remarkable improvement in the techniques of processing the images achieved in recent years, an area in which the IAC group is at the forefront. "
HUDF is the result of combining hundreds of images made with Hubble's WFC3 for more than 230 hours of observation. the data was taken by astronauts in May 2009 after the space telescope has been biting the Earth for nearly two decades.
These installations and modernization proved to be a great challenge as the whole instrument could not be tested on the ground
To improve calibration, NASA had to analyze thousands of images in different regions of the sky
