"Astronomers Probe Early Universe's Galaxy Group"
An international team of astronomers, led by researchers at the Cosmic Dawn Center in Copenhagen, has used the Hubble Space Telescope to investigate a galaxy group in the early universe. They discovered a galaxy that absorbs light rather than emitting it, and although they were unable to detect a luminous counterpart, they found another nearby star-forming galaxy. These galaxies are gravitationally bound and may eventually form a galaxy group similar to our Local Group. The researchers plan to continue studying the group to search for other members and uncover the galaxy causing the absorption.
