HENRY      star; however, we know that there were no hot stars within
(CONT'D)
           our field of view.   Therefore, the most conservative inter-

           pretation, I think, is that what we're seeing is light from

           hot stars in the galactic plane going up out of the plane

           and reflecting off interstellar dust.   There are certain

           characteristics of the spectrum, though, that don't fit that

           theory, and it's at least possible that this is extragalactic

           radiation.   I'm looking forward very much to the detailed

           computer study of this, but it's going to take a long time.


           Fifth point:    Lyman-alpha hydrogen radiation is a completely

           separate problem, and Gary Thomas at the University of

           Colorado and Charles Barthum [?] observed this from OGO-5.

           We obtained Just an enormous amount of data on the Apollo

           that's going to straighten out this picture and clarify it

           considerably.    This is hydrogen that is inside our solar

           system.    It's sunlight reflecting off this.   The hydrogen,

           Gary Thomas thinks, is hydrogen from interstellar space

           streaming through the solar system, and he is looking for-

           ward with great anticipation to getting detailed analyses

           of that.


           One more thing:    the spectrum of the Earth.   I keep saying

           "we ? " but these were the guys that were there.   We looked

           at the Earth from outside.    A lot of people have observed
