Why in News?

• The Canadian Hydrogen Intensity Mapping Experiment telescope (CHIME) telescope has made its first standalone detection of hydrogen’s faint glow from when the Universe was about 5 billion years old.
• Researchers from India’s Raman Research Institute (RRI) were part of the international collaboration.
• The findings, published in The Astrophysical Journal, could improve studies of cosmic expansion and dark energy.

Salient Features

• CHIME: Interferometric radio telescope in Canada.
• Maps the distribution of neutral hydrogen in the distant Universe.
• Helps measure the expansion of the Universe.
• Provides insights into dark energy and accelerated cosmic expansion.
• First detection achieved using CHIME’s own data alone.
• May enable faster and less expensive studies of the Universe.
