In a recent study, a team of scientists led by Chalmers University of Technology in Sweden has used the Northern Extended Millimetre Array (NOEMA) to study two galaxies in the early universe, which contain extremely productive star factories. The light from these distant galaxies takes almost 13 billion years to reach us, making them a unique window into the past.
Redshift and Observations
The study has revealed that the light from these galaxies is shifted to longer wavelengths that we can see with radio telescopes observing. This means that we can observe these galaxies as they were when the universe was only about 1.5 billion years old, providing valuable insights into the formation of galaxies and the evolution of the universe.
