"Gemini Confirms the Most Distant Radio Galaxy"
The Gemini observatory on MK confirmed that the romantically-named TGSS J1530+1049 radio galaxy is the farthest radio galaxy ever detected at around 12.5 billion light years. The region emitting radio waves is small suggesting the light from the galaxy we see comes from when it was very young and the supermassive black hole at its center was still attracting matter and growing the galaxy.

"The measured redshift of TGSS J1530+1049 places it near the end of the Epoch of Reionization, when the majority of the neutral hydrogen in the Universe was ionized by high-energy photons from young stars and other sources of radiation. "The Epoch of Reionization is very important in cosmology, but it is still not well understood," said Roderik Overzier, also of Brazil's Observatorio Nacional, and the Principal Investigator of the Gemini program. "Distant radio galaxies can be used as tools to find out more about this period.""
