A new, improved portrait of Hubble's deepest-ever view of the universe, called the eXtreme Deep Field, or XDF, looks far away and back in time to reveal faint galaxies at one ten-billionth the brightness of what the human eye can see. This is the culmination of 10 years of observing a patch of sky that contains thousands of far-flung galaxies. The full-color XDF image shows previously unseen galaxies as they looked in the early universe, billions of years ago.

Astronomers continue studying this area of sky with Hubble. Extensive ongoing observing programs, led by Harry Teplitz and Richard Ellis at the California Institute of Technology, will allow astronomers to study the deep-field galaxies with Hubble to even greater depths in ultraviolet and infrared light prior to the launch of JWST. These new results will provide even more extraordinary views of this region of the sky and will be shared with the public in the coming months.

Viewers participated in an online webinar and heard three key astronomers of the XDF observing team describe how they assembled the landmark observation. They illustrated and explained what Hubble's powerful new view tells us about the evolving universe.

  • Thanks, everyone for your wonderful comments. Many of them were answered "on-air." If you missed it, you can watch the archived YouTube broadcast!

  • @MarkElowitz: This question was raised immediately after the presenters' individual discussions of the XDF. You can review the archived YouTube video for the discussion.

  • And the James Webb Space Telescope will be our Infrared Eyes to that future, and looking back toward the beginning of the universe!

  • In this rendering of the XDF, objects that are seen only in the infrared are in red. Astronaut Jane will not see the very red objects unless they are also visible optical wavelengths.

  • And, unfortunately, they also blink every few seconds, so, they won't see nearly as deep as the combined long-exposure images.

  • Astronauts will see the colors that are in the visible part of the spectrum, but are unable to see images from the Infrared.

  • EXCELLENT DISCUSSION. Garth has said , with JWST, we may see first start/supernova, but important goal of mankind is to find intelligent life, that requires finding earth like planet in this galaxy or very difficult in other galaxies, infact singling out star from other galaxy is difficult. GOD has created human being with limitation that we cannot find other civilised life. That is a interlocking and upper limits of human intelligence.

  • Absolutely excellent!

  • Could you have achieved these results in a smaller time fram if you were not using Ansel Adams F64 aperture?

  • Super great show! You must do this more often! And meeting "the people behind the pictures " is a big deal to me!

  • Menarik sekali videonya....!

  • Has the age of the universe been changed in the scientific community by the quality of the telescope used to view the universe? Do you expect the age of the universe to change by future optics? If we are able to see galaxies whose light has taken 13 billion years to get to us I wonder how far away they are now or if they even exist by the time their light was gathered by Hubble?

  • I really loved the photo and the 3D rendition. But I would really wish for smoother renderings. It feels a bit like watching a stop motion movie and is such a shame for pictures that has taken so much hard work to produce and that really have the potential to inspire like no pictures ever before.

  • Fantastic video and format! Really appreciate you guys doing this. :)

  • amazing hypotheses. they have no idea if this is true, they are just guessing.

  • Extraordinary accomplishment and webinar...
