In 2003, the Hubble
telescope focused on a patch of blank space for about a
million seconds
–
11 days. What it found
has been called "the most important photo ever taken"
because it looked back about 13 billion years to the
beginning of the universe
–
across expanding space
perhaps 46 billion light years away
–
and found 10,000 galaxies.
Even in the farthest reaches
of space, we can see thousands of galaxies of perhaps
100 billion stars each. |
