Ultra Deep Field: Looking Out into Space, Looking Back into Time

- This six-minute visual exploration of the Hubble Ultra Deep Field showcases the characteristics and contents of this landmark observation, as well as its four-dimensional nature across both space and time. In particular, galaxies are seen to more than 12 billion light-years away / 12 billion years ago, allowing astronomers to trace the development of galaxies across cosmic time.
A deep field is a long exposure on a small field of view to observe the faintest objects possible. The Ultra Deep Field (UDF) represents the deepest visible light observation of the universe (deeper views are extensions / subsets of this 2004 image). Containing about 10,000 sources, the UDF provides a statistical sample of galaxies across the universe.
In this sequence, the three-dimensional model of the UDF data set uses NASA and other images and source catalogs. More than 5000 galaxies with cross-matched image cutout and distance measure are placed in their correct relative position throughout the long thin pyramid of the observation. To keep the fly-throughs succinct, the depth of the pyramid is shortened by a factor of a few hundred.
The visualization encompasses a suite of UDF science points in a single camera shot journey. Zooms, fades, fly-throughs, and overlay graphics visually express and highlight aspects such as the field of view, long exposure time, variety of galaxies, and extent across the observable universe. The critical idea that "looking farther out into space is also looking farther back in time" leads to examples, drawn directly from the data, of galaxy structure changing and growing over time.
The Ultra Deep Field and other deep field studies help astronomers study the distribution, characteristics, and development of galaxies across space and time.

8 dislikes from Flat earth people.
We are sooo infinitely small . . . and we worry over which person is right or, which is wrong . . . very disappointed in modern mans' inability to see the 'big picture'.
A video like this is a good way of switching off from all the problems in the world.
I’m agnostic, but astronomy does more to convince me that a higher power might exist than any crappy mortal religion ever could. This is mind-numblingly humbling and yet it’s the most beautiful thing. I am filled simultaneously with awe and dismay by this reminder of how inconceivably vast the universe is and how most of it is forever hidden from our sight. There is also a terrible sense of loss from knowing that we will never be able to reach out and set foot in any of these places. I have so many emotions to process right now!
60 years ago i looked up into the night sky in the outback of Australia in awe. I feel like that little boy again. Thank You.
This makes me think how pompous we are to declare ourselves so special that all religions and gods are interested in our tiny planet.
great that you have used my music!
What kind of person would thumbs down this presentation.
If I look at the universe more and more I feel very funny about the concept of religious fairy tales 🤣
One of the most mind expanding images in the history of humanity and personally the most profound.
I will never understand how people can view this and feel “insignificant” or “tiny”. Sure, our universe is unfathomably vast, containing a literally uncountable amount of atoms and photons. I feel amazed, honored and just downright thankful that these atoms, the ones that make up
watching this makes me and my problems feel extremely insignificant...
One of the very best presentations I've seen here. The visualizations and perspectives are amazing. Awesome!
Hubble has been incredible but I can't wait to see what James Webb has to offer!
This just blows my mind radically.
I almost cried!!! Universe is mind-blowing
The scale is truly unbelievable. In all seriousness, it's difficult to grasp the vastness of it all and somehow good ole Hubble pulls these gems. So grateful.
Mind blown at
That actually moved me in ways I've never felt before... But, it also made me feel REALLY small.
Just imagine how advanced life forms are out their in these galaxies that have come and gone, before their light even hits us.
