Researchers spotted the galaxies with NASA’s Hubble Space Telescope and the 8-meter Gemini South telescope in Chile. Hubble revealed that the galaxies are a fraction the size of most galaxies we see today, and Gemini clocked their speed by using spectroscopy.
The Gemini near-infrared spectroscopic observations required an extensive 29 hours on the sky to collect the extremely faint light from the distant galaxy, which goes by the designation 1255-0.
