Nearly as deep as the Hubble Ultra Deep Field,
which contains approximately 10 000 galaxies, this incredible image
from the NASA/ESA Space Telescope reveals thousands of colourful
galaxies in the constellation of Leo (The Lion). This vibrant view of the early Universe was captured as part of the Frontier Fields campaign,
which aims to investigate galaxy clusters in more detail than ever
before, and to explore some of the most distant galaxies in the
Universe.
Galaxy clusters are massive. They can have a tremendous
impact on their surroundings, with their immense gravity warping and
amplifying the light from more distant objects. This phenomenon, known
as gravitational lensing,
can help astronomers to see galaxies that would otherwise be too faint,
aiding our hunt for residents of the primordial Universe.
MACS
J1149.5+2223 is a galaxy cluster located approximately five billion
light-years away. In 2012, it helped astronomers uncover one of the most distant galaxies ever discovered.
Light from the young galaxy, magnified 15 times by the galaxy cluster,
first shone when our 13.7-billion-year-old Universe was a mere 500
million years old — just 3.6 per cent of its current age!
In 2014
and 2015, MACS J1149.5+2223 was observed as part of the Frontier Fields
campaign. While one of Hubble’s cameras observed the galaxy cluster
itself, another simultaneously captured the spectacular scene pictured
above, of an “unremarkable” patch of space. Referred to as a parallel field,
this image — when compared to other similar fields — will help
astronomers understand how the Universe looks in different directions.
