Hubble Ultra Deep Field
- Total exposure time of 11.3 days, taken over 16 weeks, 800 exposures and 400 Hubble orbits
- Captured about 10.000 galaxies
- Most distant galaxies are 13 billion light years away
- A look into the past when the universe only 5.8% of its current age
- Increased the current estimate of existing galaxies to 100 billion
The Hubble Ultra Deep Field image shows an estimated 10.000 galaxies. And if that isn't incredible enough, Hubble only looked at a small part of the sky. Roughly one twinty-six-millionth of the sky. To put that into perspective that is an area smaller than a 1 sq. mm piece of paper held at 1 meter away.
Zoomed in look at closest galaxies of the Hubble Ultra Deep Field
The universe is about 13.8 billion years old. And with the furthest galaxies in HUDF being over 13 billions light years away this gives us a look into the past of about 800 million years after the Big Bang.
The Hubble Deep Fields showed us that there were way more galaxies than previously thought. It was actually one of the main objectives of Hubble to measure the size and age of the universe. With this small patch of the sky of the Hubble Ultra Deep Field containing about 10.000 galaxies and further observations done by Hubble it is now estimated that the universe contains about 100 billion galaxies.
