The Hubble Space Telescope produced some of the most beautiful scenes of distant objects that humanity has ever looked at, but one particular image has constantly engulfed researchers and continues to give new discoveries.
It is a complex image of space space known as the Hubble Ultra-Deep Field, and it takes hundreds of hours to be produced with the help of the Wide Field Camera 3 telescope. Observations reveal ancient galaxies dating back to 13.2 billion years, is the "deepest" image of the space that exists. Now, the new efforts to use the original images for additional details have resulted in an even deeper look in that area of space.
In a new paper published in Astronomy and astrophysics, researchers from the Canary Islands in Spain explain how they could find weak objects hidden in Hubble's original paintings that were not visible in larger composites.
"What we did was to go back to the archive of the original images, directly as noted by HST, and to improve the combination process, for the best picture quality not only for smaller smaller galaxies, but for extended regions of the largest galaxies, "says Alejandro S.'s statement. Borlough from the Canaryas Institute of Astrophysics (IAC).
As a result, the image looks a bit strange when compared to the original composite, but it's easier to see new light sources that hide the exit from a previously black cloth. These new "ultra-deep" images show objects that are more distant than the closer galaxies in the foreground, which were dated about 13.2 billion years ago.
The pipeline used by the Hidden Light Source Reconnaissance Sources can potentially be used with other images of the universe and teach us even more about what lies farther.
