The Most Distant Galaxies Ever Seen
About | Information | History | Online | Facts | Discovery
In August, after the last repair mission on the Hubble Space Telescope, astronomers directed its newest camera towards the same area of sky where just five years ago, the first Hubble Ultra Deep field image was made and recorded a new one - this time in the near-infrared, a wavelength invisible to the human eye. Over the course of four days, the camera shutter was open for one hundred seventy three thousand seconds and astronomers collected photons that had left their galaxies over 13 billion years ago. Sensitive to slightly longer wavelengths than its predecessors, the newly installed camera known as Wide Field Camera three recorded objects that are likely the oldest galaxies ever identified, having formed only a few hundred million years after the Big Bang. Here are the results. [Music montage and interlude, couple minutes (music: Daemon portal)] Hubble's new camera looks closer towards the Big Bang than any of the earlier cameras on the Hubble Space Telescope because it collects light from near-infrared wavelengths. The expansion of the universe stretches light from hot young stars in these very distant galaxies out of the ultraviolet and visible regions of the spectrum and into near-infrared wavelengths, making them redder and invisible to the human eye. As we build instruments sensitive to longer and longer wavelengths, we are able to peer farther into the cosmos and each wavelength brings us views closer to the edge of the universe. When we focus our instruments outside the narrow band of light visible to our eyes, past the infrared and towards microwave and radio wavelengths, we open other windows that allow us to see deeper than ever before possible. The farthest we can ever hope to see reaches its limit in the microwave region of the spectrum. This is the wavelength of the radiation given off by the entire universe as it cools, which began just a few hundred thousand years after the big bang. This latest upgrade of the cameras on board the Hubble Space Telescope is setting the stage for a host of new discoveries. Because of the sensitivity to longer wavelengths, Hubble is showing us the most distant galaxies ever seen by human beings and we are able to capture glimpses of our universe like this.

Hello good evening
-
alian ......... most welcome in my planet
-
I just cannot get my head around infinite space.WHAT'S OUTSIDE IT?! But then again, what would be outside of that? How does space even exist? Just blows my mind.
-
its like old science in old schools a big wwwwwwwwoooWWWWWWWWWWWWWW..
-
wow deep astronomy wor i can see the universe now im so overwhelmed to your website love you ..
-
The music is annoying.
-
2:24 what the music is this? this shit is so powerful
-
truly humbling
-
amigos Youtube, seria bueno reactivar la opcion de traducir
-
the music is crap I will dislike for the fucking music you ruined the video
-
How ever far you look in space, you always see the same structure. Fully formed galaxies, equally spaced. Proponents of the Big Bang Theory always seem to have an excuse for this. Is it not time that we started to ask - Is the theory correct?
-
Whut iz al dem lil lights cald? N y iz dey blinkin at me?
-
music is dumb
-
I am so confused. If a galaxy is 2 billion light years away, then how did the light of that galaxy reach the lens of Hubble telescope? Can anyone explain the science of this telescope and how it works? Does it see past light years in seconds or something. So confusing :/
-
So what you are telling me you can see the past. So which galaxie do we come
-
It would be cool I my lifetime the day we discover the end or very beginning of the universe with powerful telescopes 20 billions light years away
-
Yep, and there's even better to come!
-
you talk like you know where the big bang was or the center of the universe. which direction is it ?
-
A one minute intro on a 5 min vid?
-
The most distant galaxies ever seen??? They can't even see many of the stars & planets in our own galaxy!
