ESA Gaia EDR3 is next week! I have been trying to get ready in various ways. Today Ana Bonaca (Harvard) showed me remarkable evidence that the cold stellar streams in the Milky Way halo are clustered in kinematic space, maybe also with the halo globular clusters! We discussed things to do in this area. It's perfect for EDR3 because if the clustering is real, it should improve with the improved precision of the EDR3 data.
