The latest study looked back in time to the early universe to answer some of the most-asked questions - "How do stars form in the early galaxies?" To answer this, many astronomers have been trying to detect radio signals emitted by nearby galaxies.

However, the difficulty to pick up the signal intensifies with the distance of the galaxy from the Earth. The vast expansion of the universe causes the reduction in energy due to the stretch of its wavelength.

This means, telescopes available on Earth require a natural boost to detect long-wavelength and low-energy radio waves. Now, Indian Astronomers have captured a radio signal, that too from the most distant galaxy at a specific wavelength of 21 cm line in order to unveil secrets of the early universe.

It is said to be the first 5σ detection of H I 21 cm emission from a star-forming galaxy at redshift z ∼ 1.3, which is around 9 billion years ago, while using the Giant Metrewave Radio Telescope.
