Two previously invisible galaxies that are 29 billion light-years away have been discovered by the astronomers at the University of Copenhagen's Cosmic Dawn Center.
The two heavily dust-obscured galaxies - called REBELS-12-2 and REBELS-29-2 - were found during observations with the ALMA radio telescopes in Chile s Atacama Desert.
Scientists at the University of Copenhagen’s Niels Bohr Institute have recently spotted two formerly undetectable galaxies 29 billion light-years away from Earth. The two galaxies have been undetectable to the optical lens of the Hubble Space Telescope, concealed behind a dense layer of cosmic dust that encompasses them.
