    Has there actually been physical evidence of sunspot activity on other stars other than our own sun?

    Hi Robert,

    Yes, "starspots" have been observed on many other stars. NASA's Kepler mission, which was staring at a bunch of stars to look for extrasolar planets crossing the disk, has greatly increased our observations of sunspots on other stars.
