Interactive video lesson plan for: Rare Earths in a Globular Cluster (M92) - Deep Sky Videos

Activity overview:

SEE LINKS BELOW... The composition of stars in M92 are fascinating - and great images of a Comet Garradd "passing" the cluster show us why Messier compiled his famous catalogue in the first place.

Speaking in this video are Professor Mike Merrifield from the University of Nottingham and Professor Paul Crowther from the University of Sheffield.
