With the Sun and its retinue of planets at the center of this image, we are looking at a volume of space with a radius of roughly 5 billion light years. Light from galaxies on the edge would require 5 billion years to reach the center. Observers on Earth are seeing light that was emitted by these galaxies before the solar system formed. This volume of space is much less than what is known to exist.
Astronomers in 2004 observed light from galaxies that are at least 13 billion light years away. These observations come from the European Southern Observatory's Very Large Telescope, and separately from the Keck telescope and the Hubble Space Telescope. These galaxies formed about 500 million years after the Big Bang, or about 3% of the age of the universe.
The microwave background radiation is even older. The latest information suggests that the cosmic microwave background originates from about 400,000 years after the Big Bang.
