    The apparent expansion rate a nebula is 0.43 arcsec per year. The apparent size of the nebula is about 4 by 5.7 arcmin. If the expansion rate remains constant, calculate how long it will be until the long axis of the nebula has the same apparent size as the full moon (0.50 degree or 1800 arcsec).

    Yes. I phished Galaxy's password and logged into his account to sabatage his happenings here. The next time he logs on he'll find he's suddenly losing 200 games.

    The black zone of the moon is not transparent.
    The star is behind the moon and shouldn't be visible.

    But in reality it is not a star at all, but an impact of a meteor striking the dark surface of the moon. The artist just draws it as a starlike feature.
