SUMMARY:The Milky Way Bulge
DESCRIPTION:The Milky Way Bulge\nDr. Manuela Zoccali\n\nThe structure, kine
 matics and stellar population of the Galactic bulge is very complex. Only 
 three years ago the bulge was discovered to be X-shaped, a structure belie
 ved to originate from the dynamical instabilities of a disk, through the f
 ormation and posterior heating of a bar. The study of its kinematics revea
 ls a cylindrical rotation, typical of a bar, suggesting the absence of a s
 pheroidal component. Nevertheless, the bulge stellar population is old, ha
 s a radial metallicity gradient, and element ratio indicative of a short f
 ormation timescale. All these elements conflict with a simplistic view of 
 the bulge as a heated bar, formed via "secular" evolution of a disk. I wil
 l review our knowledge of the bulge properties as traced by the 3D structu
 re, kinematics, and chemical composition of its red clump stars.
