3D transformation of the Hubble Deep Field

Reposted from 2010 to add this new information:
There are a dizzying 2 trillion galaxies in the universe, up to 20 times more than previously thought, astronomers reported on Thursday. The surprising finding, based on 3D modeling of images collected over 20 years by the Hubble Space Telescope, was published in the Astronomical Journal...

Using deep space images from Hubble, Conselice and his team painstakingly converted them into 3D to measure the number of galaxies at different times in the history of the universe.
And each of those galaxies can have a hundred billions stars...  But, according the Sky and Telescope, "we do not "also have to update the number of stars in the observable universe, which now numbers around 700 sextillion."

Lots of relevant links in this Reddit thread.


  1. The guy who makes the video has a great channel on youtube, doing weekly videos called Space Fan News. Sometimes mini documentary types like this one. If anyone is interested..

  2. I like that this shows that a lot of science is not nearly as exact as much of the public thinks.

  3. Bang goes the dark matter theory ?

    1. I've seen other discussion threads elsewhere that discussed that and said this new information does not negate the likelihood of dark matter.
