The Hubble Space Telescope has been in space for many years. There have been some challenges lately, including the one that left his camera for wide field 3 for some time inactive. Hubble returns to work, and scientists at the Astrophysics Institute in Canaria have shared a new image that takes three years. The picture is the deepest image of the universe ever taken from space.
The image was created by recovering a large amount of "lost" light around the largest galaxies in Hubble's ultra-deep field. The team uses original photos taken from the space telescope over a region known as Hubble's ultra-deep field. The team created an improved process to combine multiple images in the group to recover large amounts of light from the outer areas of the largest galaxies.
The restoration of the light emanating from the stars in the outer zones is, according to scientists, equivalent to the restoration of the light from a whole galaxy on the whole picture. Missing light indicates that some galaxies in the image were almost twice as large as previous measurements.
The image is the result of combining hundreds of individual photos taken with the wide-field camera 3. Hubble has taken pictures for 230 hours of surveillance in 2012
The wide-field camera 3 proved to be a valuable tool and was added to Hubble in 2009 by astronauts. Since the camera is added in space, it can not be tested on the ground, making the calibration a challenge. According to Alejandro C. Borlaf, the team that created the image, he said, "is possible thanks to the remarkable improvement in image processing techniques achieved in recent years, a field in which the IAC-based group. is at the forefront.
