The possible astrophysical role of superstrings is discussed. Type II superstrings (if somehow phenomenologically viable) might be seen as gravitational lenses. The superstrings of the new O(32) and E8×E8 string theories are boundaries of axion domain walls. These theories are also likely to generate more "conventional" string-like objects-stable vortex lines and flux tubes.
