The Hubble Space Telescope has produced some of the most impressive insights into the distance humanity has ever seen, but a particular image has always impressed researchers and continues to bring new discoveries.
It is a composite image of an area Known as the Hubble Ultra-Deep Field, production with the telescope's Wide Field Camera 3 took hundreds of hours. The observations showed that ancient galaxies have arisen from 13.2 billion years, and it is the "deepest" image of outer space that exists. A new attempt to examine the original images for further details led to an even deeper insight into this space.
In a new article published in Astronomy & Astrophysics Canary Islands Explorers Explain how they found weak objects in the original Hubble images, which were not visible in the larger composite.
"What we have done is to return to the archive of the original images directly observed by the HST and improve the combination process to get the best image quality not only for the smaller galaxies farther away, but also for the extended regions To reach the largest galaxies, "said Alejandro S. Borlaff of the Instituto de Asturias de Canarias (IAC) said in a statement.
The resulting image looks a bit strange compared to the original composite, but it's easier to see how the new light sources look out of a previously pitch-black canvas. These new ultra-deep images show objects farther away than the closer galaxies in the foreground, which were dated about 13.2 billion years ago.
The pipeline that discovered hidden sources of light could potentially be used with other images of the room and teach you more about what lies behind it.
