Observe the galaxies formed 10 billion years ago

British astronomers have created the most sensitive infrared cosmic map ever made. Combining data over a period of three years, they created an image containing 100,000 galaxies on an area four times the size of the entire moon.

Due to the limited speed of light, these observations allow astronomers to return to the past more than 10 billion years, creating images of galaxies during the period of the new universe. The picture was so big and clear that it could study thousands of galaxies in the early epochs.

By observing in infrared rays, astronomers can now look back to the past because light from the farthest galaxies is shifted toward redder wavelengths as light travels across the wide universe. great.

Dr Sebastien Foucaud of the University of Nottingham said: 'These observations can be compared with deep ice cores in Antarctica. This ultra-clear image allows us to look back and observe galaxies evolving at different times in the history of the universe, during the time of returning to a billion years after the Big Bang. '

One of the main purposes is to understand when the largest and thinnest galaxies formed at a distant past, a problem that has not been understood for a long time in the space industry. 'For the first time, we have a cosmic photograph big enough to be able to see galaxies and get clear details about when they formed,' said Dr. Foucaud.

The photo comes from the UKIRT Infrared Telescope located in Hawaii.

This is a very small part of the clearest infrared image ever taken.In the picture is a relatively close spiral galaxy.Most light red objects on the background are huge galaxies with a distance of 10 billion light-years.
