Using the large Subaru telescope atop Hawaii's Mauna Kea, researchers recorded a galaxy as it appeared just 780 million years after the Big Bang. The universe is now 13.7 billion years old.

For their study, Masanori Iye of the National Astronomical Observatory of Japan in Tokyo and his colleagues used a filter that selects near-infrared light corresponding to radiation emitted by hydrogen atoms in distant galaxies. The distant galaxies emit this light at ultraviolet wavelengths, but the expansion of the universe shifts that radiation into longer, infrared wavelengths that Subaru can dete
