In 1974 We Transmitted a Message Toward the Globular Cluster

question 3

Multiple Choice

In 1974 we transmitted a message toward the globular cluster M13 which is 21,000 ly away. What is one reason that this object was probably not ideal for sending a message to?

• A) it is so far away that we will probably have stopped communicating before we receive and return signal
• B) globular clusters contain young, high mass stars with insufficiently long main sequence lifetimes and hence are unsuitable places for life
• C) the message will be absorbed by interstellar dust before it reaches the cluster
• D) globular clusters contain, old, low mass stars with fewer heavy elements and hence are not ideal places for life
