10,000 Galaxies

 
10,000 Galaxies

Those specks of light aren't stars. They're entire galaxies.
Look closer at the Hubble Ultra Deep Field.

No telescope has ever captured more cosmic beauty than the Hubble Space Telescope--or produced an image more humbling than the Hubble Ultra Deep Field.

From the ground, the spot of space that Hubble's scientists studied for the image seems empty and desolate. But when Hubble focused its sensitive eyes there for a million seconds, 10,000 galaxies came into view--some more than 13 billion light years away. It's the farthest (and furthest back in time) that human eyes have ever seen.

One image, one spot of sky, 10,000 galaxies. That's humbling enough. But if a single image can reveal 10,000 galaxies, just how many galaxies are there? How many "billions and billions" of stars light the night sky?
