The XDF is a portrait of a small area of space in the southern constellation Fornax, and spans only a small fraction of the area of the full moon. "XDF allows us to explore further back in time than ever before. With that information, Hubble could build the most detailed picture possible of the universe around us, according to a statement published by the team behind the telescope. The farthest-away galaxies are 13.2 billion light-years from Earth, meaning their light has taken 13.2 billion years to travel to Hubble's cameras. Image released Sept. 25, 2012.

The telescope, a collaboration between NASA and the European Space Agency, is still going strong, and scientists say the scope should be able to function through at least 2018. Milky Way Galaxy was the entire universe. "The light from those past events is just arriving at Earth now, and so the XDF is a 'time tunnel into the distant past,'" according to a NASA statement.

The XDF is a very small fraction of sky area, but provides a "core sample" of the heavens over 13 billion light-years. Within that region, Hubble has revealed 5,500 galaxies, many of which existed shortly after the birth of the universe.

GSFC When Edwin Hubble Hubble was only able to image these objects by amassing light in 2,000 images of the same area, with a total exposure time of 2 million seconds, through two of its cameras: the Advanced Camera for Surveys and the Wide Field Camera 3. Only the accumulated light gathered over so many observation sessions can reveal such distant objects, some of which are one ten-billionth the brightness that the human eye can see. surprisingly vast cosmos.

Explanation: Some of the very tiny, faint galaxies could be the seeds from which the biggest galaxies around today grew.

There was a problem. "The youngest galaxy found in the XDF existed just 450 million years after the universe's birth in the Big Bang.". What happens at the center of a black hole?
