Smallest, Faintest Galaxies of the Ancient Universe Spotted
Two of NASA’s most powerful space telescopes have teamed up to shed new light on the early history of the universe.
The Hubble Space Telescope utilized a natural zoom lens to capture nearly 60 of the smallest, faintest galaxies ever spotted in the distant universe. In a separate study, observations by the Spitzer Space Telescope helped researchers determine the masses of four of the brightest early galaxies after Hubble picked them out.
Both results could be followed up by NASA’s James Webb Space Telescope, an $8.8 billion observatory slated to be launched in late 2018, officials said.
