For most of human history, the only light we knew came from the sky. By day, the sun. By night, an uncountable number of stars. From the beginning, our ancestors believed that the sun and the stars were heavenly, out of this world and they were right.
We've been watching the sky for thousands of years, but until recently we couldn't see well enough to understand our connection to the cosmos. But now, our astronomical vision has sharpened; we can see farther and clearer. We can observe objects that are invisible to human eyes. Our increasingly improving vision has allowed us to make great discoveries revealing an astonishing and wonderful universe. What follows are some of the greatest discoveries of astronomy.
