The photo at right is the earliest image ever taken of our universe.It represents looking back in time 13 billion years. The picture was taken by the Hubble telescope.
The universe is about 13.7 billion years old, and scientists want to see far enough out in space to catch images of the first galaxies and stars formed after the Big Bang. To achieve this, a new telescope—the $4.5 billion James Webb telescope—will be launched in about 4 years.
If successful, the James Webb telescope will be able to see across time to the very earliest years of the universe, perhaps within a few million years of its creation.
Our question is: what existed before the Big Bang?
