Astronomers have created the largest and most complete "history book" of 265,000 galaxies in a single image, dating from 13.3 billion years to 500 million years after the Big Bang.
They used 16-year observations of the Hubble Space Telescope of the American space agency NASA, which tells the evolutionary history of the universe in an overview with nearly 7,500 views.
The picture shows how galaxies change over time, become giant galaxies, and more fragile and distant galaxies are only ten billion light than the human eye can see, according to a NASA press release. this week.
The galaxies allow astronomers to track the expansion of the universe, provide clues about the underlying physics of the cosmos, show when the chemical elements originated and enable the conditions that eventually led to the emergence of our solar system and our life.
"This image contains the full story of the growth of galaxies in the universe, from their time as children until they become adults in their own right," said Garth Illingworth of the University of California, Santa Cruz, leader The team that assembled the image.
This new mosaic of images is the first in a series of images from Hubble Legacy Field. The team is working on a second set of images, totaling over 5,200 Hubble views in another area of the sky.
