Perspectives

ASTRONOMY:
Putting Galaxies on the Scale

Francesco Bertola

The properties of galaxies are increasingly becoming accessible to observational astronomy. Comparison of near and distant galaxies provides clues to their evolution. In his Perspective, Bertola reports from a recent workshop that covered one crucial aspect of this comparison: galactic mass. Topics discussed in the Perspective range from the mass of our own galaxy to how galaxies may have evolved.
