Are we alone in the universe?

­Claude Canizarez – principal investigator on NASA's Chandra X-ray Observatory

Today my guest is Claude Canizares.

The universe and space travel have occupied people’s minds since they found out what the universe was. Science fiction books and movies keep speculating about the possible scenarios of encounters with space aliens, saying we would either be saved or doomed. Tabloids are full of those who claim they were kidnapped by UFOs. Today on Spotlight, we will hear a clear and authoritative voice among this hullaballoo from the principal investigator on NASA's Chandra X-ray Observatory, Claude Canizares.
