question 14

Multiple Choice

A charming friend of yours who has been reading a little bit about astronomy accompanies you to the campus observatory and asks to see the kind of star that our Sun will ultimately become, long, long after it has turned into a white dwarf. Why is the astronomer on duty going to have a bit of a problem satisfying her request?

• A) after being a white dwarf, the Sun will explode, and there will be nothing left to see
• B) the universe is not even old enough to have produced any white dwarfs yet
• C) all the old stars in our Galaxy are located in globular clusters and all of these are too far away to be seen with the kind of telescope a college or university campus would have
• D) after a white dwarf cools off it becomes too cold and dark to emit visible light
• E) astronomers only let people with PhD's look at these stellar corpses; it's like an initiation rite for those who become astronomers
