Incredible images from the Hubble telescope reveal the enormity of the universe as it groups together 7,500 images of galaxies aged 13.3 billion years old.
- The mosaic image includes 265,000 galaxies captured by Hubble
- It includes ancient galaxies formed only 500 million years after the Big Bang
- To look deeper into space, is to look earlier in the history of the universe
- The most distant galaxies are 1 in 10 billion of the brightness of what our eyes can see
A stunning mosaic image combining nearly 7,500 photos taken by NASA's Hubble Telescope for 16 years was published by NASA.
It is presented as "the largest and most comprehensive history book in the universe".
The image, as well as a video accompanying the zoom out of the telescope, include 265,000 galaxies dating back 13.3 billion years.
To put the distance between these galaxies into perspective, the scientists created a video that zooms out of the farthest point captured to reveal a panorama of the sky.
The image is the end result of a project to combine data from 31 Hubble programs made by different teams of astronomers.
A tiled image of nearly 7,500 photos taken by NASA's Hubble Telescope (pictured) is "the largest and most comprehensive history book in the universe," says a spokesman. scientist.
The Hubble telescope remains one of humanity's most powerful tools for exploring the universe, even 29 years after its mission.
As the telescope looks further into space in terms of distance, it also means that they are looking further back in time, towards the beginning of the universe.
The farthest galaxies shown by the magnified images represent 1 in 10 billion of the brightness of what the human eye can see without a telescope and were created 13.3 billion years ago.
The Hubble Legacy Field (HLF) image includes images from the eXtreme Deep Field (XDF) survey that provides the widest view of the universe.
The complete mosaic and its individual captures are available via the MAST (Archive for Mikulski Space Telescopes), an online database of Hubble astronomical data and other NASA missions.
To put into perspective the distance that separates these ancient galaxies, scientists have created a video that zooms out (indicated by the squares) of the farthest point captured to reveal a panorama of the universe.
Dr. Pieter van Dokkum, astronomy professor of the Sol Goldman family at Yale and co-researcher of the team that assembled the image, said: "Hubble has examined this area of the sky on numerous occasions over many years. these photographs in a single wide-angle image of very high quality.
"It's like having a history book of the universe in one image."
The HLF image contains 100 times more galaxies than previous deep field surveys, in part because it covers a wider view of the Earth that is almost the width of the moon.
Dr. Garth Illingworth of the University of California at Santa Cruz, head of NASA's research team, said: "This image contains the complete history of galaxy growth. in the universe, from their childhood up to their growth. & # 39; adult & # 39; in its own right.
"No image will surpass it before the launch of future space telescopes."

The study of the oldest galaxies allows astronomers to track the expansion of the universe as well as the underlying chemical and physical changes that have led to life on Earth.
Dr. Van Dokkum said astronomers were hoping to expand the range of multiple wavelengths of NASA's wide-field survey geodesic telescope images, which would allow him to explore an area. even more extensive than the HLF.
Scientists are working on a second set of mosaic images combining more than 5,200 captures made by the Hubble telescope from another area of the sky.
WHAT DOES TELESCOPE HUBBLE SPACE DO?

The Hubble Space Telescope was launched jointly by NASA and the European Space Agency.
The Hubble is a long-term space observatory.
The Hubble observes ultraviolet wavelengths, which the atmosphere filters, and captures visible light.
"The Hubble Space Telescope has made some of the most spectacular discoveries in the history of astronomy," says a statement on the telescope.
The machines are located more than 370 km above the ground.
It can capture light through its "eyes", five times more focused than telescopes on the ground.
The Hubble focuses on areas located in the depths of outer space "where some of the deepest mysteries are still buried in the mists of time."
