Query: Ten Facts of Life for Distant Supersoft Sources   First discovered in the Magellanic Clouds and in the Milky Way, the largest
pools of luminous supersoft X-ray sources (SSSs) now known lie in M31 and in
more distant galaxies. Hundreds of newly-discovered SSSs are helping us to test
models for Type Ia supernovae and to identify SSSs that may represent a wider
range of physical systems, including accreting intermediate-mass black holes.
In this short report we list ten intriguing facts about distant SSSs.
