Astronomers capture radio signal from ancient galaxy at record-breaking distance

[smp]

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."

Hi Stephen. Wow, detecting radio signals from really deep space at the 21-centimeter wavelength line is amazing. Thanks for finding and sharing this very interesting link with us Stephen and keep up the great astronomy reporting news.
