ESO's VISTA telescope has created the widest deep view of the sky ever made using infrared light. This new picture of an unremarkable patch of sky comes from the UltraVISTA survey and reveals more than 200 000 galaxies. It forms just one part of a huge collection of fully processed images from all the VISTA surveys that is now being made available by ESO to astronomers worldwide. UltraVISTA is a treasure trove that is being used to study distant galaxies in the early Universe as well as for many other science projects.



"COSMOS" field

ESO’s VISTA telescope has been trained on the same patch of sky repeatedly to slowly accumulate the very dim light of the most distant galaxies. In total more than six thousand separate exposures with a total effective exposure time of 55 hours, taken through five different coloured filters, have been combined to create this picture. This image from the UltraVISTA survey is the deepest infrared view of the sky of its size ever taken.


Read the full press release nd see the hi-res view at ESO

The UltraVISTA survey has been devoted to the COSMOS field ( eso1124, heic0701), an apparently almost empty patch of sky which has already been extensively studied using other telescopes, including the NASA/ESA Hubble Space Telescope. UltraVISTA is the deepest of the six VISTA surveys by far and reveals the faintest objects.



This chart shows the location of the COSMOS field in the constellation of Sextans (The Sextant). This map shows most of the stars visible to the unaided eye under good conditions, and the COSMOS field is marked as a blue square. Through a small telescope nothing can be seen here apart from a few faint stars, but this small patch of sky has been studied in great detail by telescopes on the ground and in space.

Take also a look at this amazing video where we literally plunge into deep space:

Zooming into VISTA's deep view of the COSMOS field
This video offers a zoom on UltraVISTA — the widest deep view of the sky ever taken using infrared light. The sequence starts with view of most of the sky. We zoom towards the faint constellation of Sextans (The Sextant) and then close in on a much-studied region of sky called the COSMOS field. The final very detailed infrared view comes from the VISTA telescope at ESO’s Paranal Observatory.

This is awesome! And this is only a small portion of the sky! Thank you op

Nice! I for one also think it's weird how people can't get it in their heads that we are not alone in this massive, ultra massive place. There has to be other civilizations that are say million years ahead in their technology and also those that are behind us. Apparently this picture is only a small fraction of the "sky" as well... Just imagine......

I do also believe that others have already been here and are still here today, watching, observing life... I know I would. It's creation in it's finest any way you look at it.

Hi 11/8
I love deep space photos. I hope these are enhanced like some of the nebula ones from hubble.
But I am having trouble getting anything to appear on my monitor.
Maybe there is to much data in the files. All I get is the windows with a little red x. I am a computer nerd. Can you make a suggestion that might help me see these beauties?
thanks 11/8

Cancel, they are appearing slowly now

Yes, I forgot to add that due to the size of the picture, I could possibly slow down your computer!

Yes! 55 hours is already a very long exposure time, I guess that they used some filters to decrease the brightness of the brightest stars, otherwise their luminosity could impress the whole scene.

hahah I love this comment xD

I cant wait to join our space brothers/sisters as well We are getting there, just open up your minds and hearts <3 The Earth and World (with all its energies) is rapidly changing, we are 'efficiently' adjusting to it
