Astronomers detect radio signal from most distant galaxy

Using gravitational lensing, astronomers have detected radio signals from the most distant galaxies ever seen. Gravitational lensing amplifies signals from distant galaxies so that they can be detected by Earth-based telescopes. The signal comes from the star-forming galaxy SDSSJ0826+5630, emitted when our universe was only 4.9 billion years old, 8.8 billion years ago. The Giant Metrewave radio telescope in India detected the signal at a wavelength along the hydrogen line. The study was published in the journal Monthly Notices of the Royal Astronomical Society.
