In 2014, NASA released
this updated version
of the iconic Hubble
Ultra Deep Field image.
The original zoomed
in on a tiny section of
apparently empty sky in
the Southern Hemisphere
using both visible and
near-infrared light.
For Hubble Ultra Deep
Field 2014, astronomers
collected and included
ultraviolet data, which
helps reveal the youngest,
largest, and hottest stars
in the universe. NASA, ESA,
