SUMMARY:Things you should know about the Milky Way\, Astronomy Colloqu
 ium\, Bob Benjamin\, UW-Madison/UW-Whitewater
DESCRIPTION:The last several years have seen truly remarkable advances
  in our understanding of the Milky Way Galaxy\, from the identificatio
 n of stellar streams and stellar ensembles associated with the formati
 on history of our Galaxy  to the identification and characterization o
 f thousands of stellar clusters to the development of remarkably accur
 ate three-dimensional maps of the distribution of interstellar dust ou
 t to three kiloparsecs from the Sun. A lot of these advances are due t
 o the availability of high precisions parallaxes and proper motions fr
 om the ESA Gaia mission and VLBI BeSSeL program\;  large-scale program
 s of stellar spectroscopy and advances in angular resolution and sensi
 tivity of surveys of the gas and star forming content of the Milky Way
  are also major contributing factors. The net effect of all of these c
 hanges is to turn the Milky Way into an excellent laboratory for study
 ing the physical processes by which  galaxies convert their gas into s
 tars\; this is occuring at the same moment as JWST observations are pr
 oviding astounding external views of the same processes in nearby gala
 xies.  In this colloquium\, I will review the history of attempts to a
 scertain the structure of the Galaxy\, highlight some of the key thing
 s we’ve learned about our Galaxy over the last few years\, and provi
 de a preview of things to come.
