Two new galaxies previously hidden behind cosmic dust found by scientists
New Delhi : Scientists from the University of Copenhagen have discovered two new galaxies which were believed to be hidden behind the cosmic dust. The two galaxies are located billions of light-years away from Earth. The new revelation will definitely question the creation of universe as mentioned in the Big Bang theory.
The latest findings have been published in the recent edition of the scientific journal, Nature on Monday.
The scientists revealed that the galaxies were already present there but we could not spot them due to a thick layer of cosmic dust that surrounds them. Now, the discovery has been made possible with the help of the ALMA radio telescopes (Atacama Large Millimeter Array) situated in Chile’s Atacama Desert, which specialises in capturing radio waves emitted from the coldest, darkest depths of the universe.
The researchers have said that with the finding of two new galaxies, it is possible that many more galaxies are present and yet to be discovered. These galaxies indicate that the very early universe contains many giant celestial objects. They simply lie hidden behind dust consisting of small particles from stars.
Associate Professor Pascal Oesch of the Cosmic Dawn Center at the Niels Bohr Institute and one of the authors of the study said in a statement, "Our discovery demonstrates that up to one in five of the earliest galaxies may have been missing from our map of the heavens. Before we can start to understand when and how galaxies formed in the Universe, we first need a proper accounting."
The research also highlights the crucial role that will be played by the James Webb Space Telescope, which is expected to be launched into orbit on the December 18. With its advanced technology, scientists expect to lift the cosmic air of confusion and receive a much clearer picture of our universe.
