Astronomers capture radio signal from ancient galaxy at record-breaking distance
From Space.com:
"Astronomers have detected a radio signal from the most distant galaxy yet.
The signal was detected at a special and significant wavelength known as the "21-centimeter line" or the "hydrogen line," which is emitted by neutral hydrogen atoms. The detection of the hydrogen line from such a galaxy so far away — and therefore so early in the universe — by the Giant Metrewave Radio Telescope in India could mean astronomers are ready to begin investigating the formation of the earliest stars and galaxies."
