This mission will provide a very large data set ( ˜ 10^9 stars) with an unprecedent level of detail in phase space (tens of μs). However, before recovering useful information, sampling biases, observational errors and the stellar galactic background must be taken into account....

The Magellanic Stream was also thought to have formed during previous close orbits, but again, astronomers must seek another explanation. It seems that there are still many secrets to be revealed and stories to be told about our nearest galactic neighbor. Until we have those answers, just marv...
. On the other hand, these are also those GCs for which more precise data can be obtained. A similar bias can of course be present in case spectroscopy is used to define the populations fractions. It would be interesting to extend the same kind of studies to a sample fully representative...
