Description
I will present new results concerning the interstellar medium within
15 parsecs of the Sun. The analysis of high resolution ultraviolet spectra for
the lines of sight toward a large number of nearby stars provides radial
measurements that are consistent with 15 velocity vectors describing the flow
of gas in warm interstellar clouds. This work provides new and very interesting
information on the dynamics and physical properties of these clouds and
locations in the sky where cloud-cloud interactions may occur. One unexpected
result is that the large amplitude radio scintillation observed toward several
AGN and pulsars can now be simply explained by turbulence where nearby clouds
interact.
