  We summarize the Focus Meeting (FM10) "Nano Dust in Space and Astrophysics"
held in Vienna, Austria on 28-29 August 2018 during the 30th General Assembly
of the International Astronomical Union (IAU). The theme of this focus meeting
is related to the detection, characterization and modeling of nano particles
--- cosmic dust of sizes of roughly 1 to 100 nm --- in space environments like
the interstellar medium, planetary debris disks, the heliosphere, the vicinity
of the Sun and planetary atmospheres, and the space near Earth. Discussions
focus on nano dust that forms from condensations and collisions and from
planetary objects, as well as its interactions with space plasmas like the
solar and stellar winds, atmospheres and magnetospheres. A particular goal is
to bring together space scientists, astronomers, astrophysicists, and
laboratory experimentalists and combine their knowledge to reach cross
fertilization of different disciplines.
