Hubble Deep Field

This image from the Hubble Space Telescope provides a glimpse at a tiny sliver of the universe?like looking at the sky through a straw. It shows at least 1,500 galaxies at varying distances and at different stages of evolution. Some galaxies are so far away, we see them as they were billions of years ago, representing what the universe looked like in its earliest stage?perhaps less than a billion years after the big bang.

To create this image, scientists pointed the Hubble Space Telescope at a single spot for 10 days to capture even the faintest objects. By studying Hubble deep field, scientists hope to answer many questions about the number, evolution, and ultimate fate of galaxies in the universe.
