Tons of space images have been captured by the Hubble Space Telescope since 1990 when it entered orbit. Now, a mosaic photo has been put together by NASA using 16 years’ worth of data thanks to which one of the widest views of the universe has been created. Hubble Legacy Field, the image we are talking about, contains 7,500 individual exposures which have been captured by 31 different programs in wavelengths spanning from ultraviolet to near-infrared light.
A region in the sly is encompassed by the image and includes older Hubble mosaics’ regions the eXtreme Deep Field and the Ultra Deep Field which put together 265,000 galaxies. Previously, deep field images would only contain 30 times less as they do now.
Hubble Space Telescope Captured 16 Years Of Data In One Stunning Image Of The Universe
According to NASA, our most in-depth look into the universe remains the eXtreme Deep Field, but we also get a glimpse of the early cosmos thanks to the Legacy Field, that being a time when young and small galaxies would merge and collide with other galaxies. The state of galaxies is being shown by this image as far back as 13.3 billion years ago or after the Big Bang with 500 million years.
However, NASA says that the Legacy Field’s scope will not be surpassed by any image until future telescopes make their way to orbit. According to the leader of the team that assembled the image, Garth Illingworth:
“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…’ We’ve put together this mosaic as a tool to be used by us and by other astronomers. 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.”
