Radio Signal Detected 9 Billion Light-Years Away from Earth Captured

(FOX NEWS) – A radio signal 9 billion light-years away from Earth has been captured in a record-breaking recording, Space.com said Friday.
The signal was detected by a unique wavelength known as a “21-centimeter line” or the “hydrogen line,” which is reportedly emitted by neutral hydrogen atoms.
The signal captured by the Giant Metrewave Radio Telescope in India could mean that scientists can start investigating the formation of some of the earliest stars and galaxies, the report said.
Researchers detected the signal from a “star-forming galaxy” titled SDSSJ0826+5630, which was emitted when the 13.8 billion-year-old Milky Way – the galaxy where Earth resides – was just 4.9 billion years old.
