Fascinating.
radio signals originating from an extremely distant galaxy, using the Giant Metrewave Radio Telescope in India.
It's especially noteworthy as atomic hydrogen is the basic fuel that drives the formation of stars, meaning that the research could help us understand how stars form in galaxies billions of light-years away.The astronomers took advantage of gravitational lensing, the phenomenon in which a massive body located between the source and the observer, such as a galaxy, bends light being emitted by distant source.
"But thanks to the help of a naturally occurring phenomenon called gravitational lensing, we can capture a faint signal from a record-breaking distance," Chakraborty said.
