Astronomers from the Indian Institute of Science (IISc) and McGill University have detected a radio signal from a faraway galaxy using data from the Giant Metrewave Radio Telescope (GMRT) in Pune. The detected signal was emitted when the universe was just 4.9 billion years old, and has been tracked to a phenomenon called gravitational lensing. This phenomenon causes the light emitted by the source to bend due to the presence of another massive body, resulting in a magnified signal. The detection is the largest ever, and far by a huge margin. Understanding the evolution of neutral gas is crucial in understanding the evolution of galaxies.
