I talk to Dr Maria Lugaro on the topic of pre-solar grains. Topics we cover include:

– What are pre-solar grains?
– Do they only exist in our solar system?
– How big are they?
– How do we capture pre-solar grains on Earth?
– How do we determine if grains are pre-solar?
– How do the grains form?
– What percentage of material in the solar system is pre-solar?
– How is the information from these grains useful in understanding the solar system, and the evolution of the solar system?
– The age of this area of study.
– How these grains are studied and analysed.

Also featured is the listener of the episode, and listener feedback.
