There is a lot of exiting stuff: observing Einstein cross visually, GAI mapping mission, MACHO detection... Perhaps we could start with that...

  > There is a lot of exiting stuff: observing Einstein cross visually, GAI mapping mission, MACHO detection... Perhaps we could start with that... I am not sure what you mean. We have had optical observations of at least one Einsten cross since the late 80s / early 90s[0, 1]. Signs of MACHOs were detected in 1995[2]. I don't know what a "GAI mapping mission" is, so I cannot comment on that.
