Se presentan algunos comentarios sobre el origen probable del agua en nuestro planeta, en el contexto de la fonnación del sistema solar a partir de una nebulosa de gases y polvo posiblemente similar a la de la constelación de Orión. Las nebulosas y las nubes moleculares frías contienen, entre otras sustancias, cantidades importantes de agua como hielo y como gas, de modo que el agua del sistema solar habría estado presente en la nebulosa precursora. La degasificación planetaria sería la responsable de la liberación del agua de hidratación de las rocas como vapor, el que una vez condensado habría originado los océanos. Alternativamente, el agua planetaria podría haber sido aportada por el intenso bombardeo de cometas (ricos en hielo) que siguió al periodo acrecional. Independientemente de la teoría que se considere, nla existencia de agua en la Galaxia y su presencia en nuestro planeta se discuten en relación con la estabilidad molecular. En sendos apartados se mencionan los estudios sobre hielos antárticos antiguos y se discute someramente aspectos relativos a la estabilidad de las uniones químicas involucradas en la molécula de agua. Se incluyen además notas aclaratorias.
