and it will recombine if given time to heal its wounds."     ---- Hannes Alfvén

Dust Work

I'm an INAF and PSI researcher investigating the charging processes and the dynamics of cosmic dust in circumplanetary magnetospheres.

The dust wakes out of its slumber and I follow its passage. From volcanoes on moons, through comet breezes, Atop bookshelves in rooms, expelled by human sneezes, From disks of new stars into emerald-blue planets, The dust is a piece of me, or am I a piece of dust? We fly from the ecliptic brightness, feel comforted by the local fluff, and drink a ceylon tea at the cosmic tea table with our friends from beta Pic. They don't laugh at my jokes, but I smile anyway. Amara Lynn Graps March 2001
