Light is the only connection we have with the Universe beyond our solar
system, and the only connection our ancestors had with anything beyond
Earth. Follow the light and we can journey from the confines of our
planet to other worlds that orbit the Sun without ever dreaming of
spacecraft. To look up is to look back in time, because the ancient
beams of light are messengers from the Universe's distant past.
