According to a statement by NASA, astronomers have gathered the image of all the galaxies together in space as it took 16-years of data from the Hubble Space Telescope, and after keeping everything together it consists of nearly 7,500 exposures. ‘Hubble Legacy Field’ wide view images have almost 265,000 galaxies in it which go back to 13 billion years to 500 million years after the big bang as it also shows that how much they have changed by the time.
The eXtreme Deep Field (XDF) which was organized back in 2012 includes 5,500 galaxies and no to forget, these galaxies are also included in Hubble Mosiac as it contains 30 times as many galaxies as XDF. NASA officials conveyed in a statement, “The faintest and farthest galaxies are just one ten-billionth the brightness of what the human eye can see.” NASA also claims that no other telescope will be able to beat Hubble Legacy Field till the next generation space telescopes launch in the near future.
Garth Illingworth, the leader of the Hubble Legacy Field image team said, “Now that we have gone wider than in previous surveys, we are harvesting many more distant galaxies in the largest such dataset ever produced by Hubble, this one image contains the full history of the growth of galaxies in the universe, from their time as ‘infants’ to when they grew into fully fledged ‘adults. The expectation is that this survey will lead to an even more coherent, in-depth and greater understanding of the universe’s evolution in the coming years.”
Another masterpiece of space telescope will allow astronomers to have a deeper peek into the legacy field. The telescope will be called the James Webb Space Telescope and will probably launch in 2021. The astronomers are way happy about the images and it gave hope to the team of astronomers to perform new studies and researches to look deeper into the legacy field.Tags: eXtreme Deep Field, Hubble Legacy Field, NASA
