The Frontier Fields: where primordial galaxies lurk

29 September 2016 Astronomy Now

In the ongoing hunt for the universe’s earliest galaxies, NASA has wrapped up its observations for the Frontier Fields project. This ambitious venture has combined the power of all three of NASA’s orbital observatories — the Spitzer Space Telescope, the Hubble Space Telescope and the Chandra X-ray Observatory — to delve as far back in time and space as current technology can allow.


Hubble team breaks cosmic distance record
