Using the Frederick C. Gillett Gemini North Telescope in Mauna Kea, Hawaii, Glazebrook and a multinational team of researchers called the Gemini Deep Deep Survey (GDDS) employed a special technique called the "Nod and Shuffle" to peer into what had traditionally been a cosmological blind spot. Called "the Redshift Desert," this era — 8 billion to 11 billion years ago, when the universe was only 3 billion to 6 billion years old — has remained relatively unexplored until now, mainly because of the challenges inherent in collecting data from the faintest galactic light ever to be dissected into the rainbow of colors called a spectrum. In all, the team collected and analyzed spectra from 300 galaxies, making it the most complete sample ever taken from the Redshift Desert.
