On 2nd May, scientists have released a new comprehensive image of the Universe using the observations of the Hubble Space Telescope (HST). It’s like a panorama of galactic history containing numerous old galaxies and infants, well-established worlds and an occasional train wreck.
Hubble Satellite Project to Understand Universe
The scientists have created the latest image of the Universe using more than 7,500 Hubble Space Telescope (HST) observations taken over 16 years. So, they have named it “Hubble Legacy field”.
They are considering it the most comprehensive view of the universe to date since it contains thousands of observations taken by HST for such a long period of more than 16 years. The final composite image of the Hubble Legacy Field contains around 265,000 galaxies. Some of the galaxies are so far away that it took billions of years for Hubble to capture their light.
The lead researcher of this project, Garth Illingworth from the University of California, claimed that this image contains a full history of how the galaxies grew in the universe. This begins from their time as ‘infants’ to when they developed into fully fledged galaxies.
They started working on this project since 1995 when they decided to use Hubble satellite to study how far the galaxies are? They started capturing Hubble’s observations since then.
In the beginning, Hubble stared on a seemingly pitch-black piece scrap of space for 1 million seconds for 10 consecutive days. As the time paid-off, it captured the feeble light of myriad never-before-seen galaxies.
The latest Hubble Legacy Field image reveals thousands of galaxies that had never been seen before by us. Some of the galaxies shone with a light that dated to the early universe.
NASA plans to dispatch another eye in the sky called the Wide Field Infrared Survey Telescope (WFIRST) in mid of the 2020s. They intend to capture multiple times the perspective on a run of the mill Hubble picture using WFIRST.
The scientists claim that studying far-flung galaxies reveal to them how the cosmos looked like billions of years ago when those lights just flickered. So far, the Hubble satellite has taken tens of thousands of hours of observations. It has been capturing galaxies throughout the day on a daily basis for nearly three decades. This new image will inspire other astronomers to research more into these worlds. This will also help in looking into the causes of galactic “train wrecks”.
