NASA Discovers Earth’s Most Remote Galaxies
In a major breakthrough, astronomers at NASA have revealed the most distant galaxies using the latest technique, redshift. The galaxies are found to have redshift of around 10.
‘Redshift’ is the method of measuring the distance of the object using the light shift mechanism. According to the technique, the more distant an object, the more its light is shifted to the red light region and hence the greater the redshift.
Previously, NASA’s Hubble Space Telescope had prepared the deepest image ever of the Universe using the Wide Field Camera 3 (WFC3). The researchers are also taking the clue from different resources like taking the photographs of the full moon. This could help the scientists in understanding the mystery of the evolution of the universe.
The other distant celestial object having the most redshift is the ‘gamma ray burst’, which has a redshift of 8.2. It was discovered in April this year. According to astronomer Garth Illingworth at the University of California, at present there are about three galaxies with redshifts of around 10. They were supposed to be existed at an early stage of evolution.
“Even though it’s not really unexpected, finding galaxies at such early times is hugely exciting,” said Illingworth. “There’s no smoking gun, but we’re confident that this is what we’re really seeing,” he added. “There are still a lot of questions to address,” said Illingworth, another researcher working on the project.
