CHIME Telescope and Hydrogen Intensity Mapping
CHIME, the Canadian Hydrogen Intensity Mapping Experiment, is a radio telescope in Canada built to chart hydrogen gas across the distant universe and so work out how the cosmos has expanded. It is in the news because a study published on 30 September 2026, with collaborators at India's Raman Research Institute, reports its first detection of hydrogen's faint glow from a universe about five billion years old made with its own data alone.
