This nebula was discovered by the French astronomer Charles Messier while searching for comets in late January 1779. Messier’s report of his independent discovery of Comet Bode reached fellow French astronomer Antoine Darquier de Pellepoix two weeks later, who then independently rediscovered the nebula while following the comet. Darquier later reported that it was “. . . as large as Jupiter and resembles a planet which is fading” (which may have contributed to the use of the “planetary nebula” terminology). It would be entered into Messier’s catalogue as the 57th object. Messier and German-born astronomer William Herschel speculated that the nebula was formed by multiple faint stars that were unresolvable with his telescope.

The "Dagwood Sandwich" Moon. Earlier models of Ganymede's oceans were based on the assumption that the existence of salt didn't change the nature of liquid very much with pressure. However, Dr. Vance and his colleagues found, through laboratory experiments, that salt does increase the density of liquids under the extreme conditions hidden deep within Ganymede and similar icy moons with subsurface bodies of water. Imagine adding table salt to a glass of water. Instead of increasing in volume, the liquid will actually shrink and become denser. The reason for this is that salt ions lure water molecules. "Ganymede's ocean might be organized like a Dagwood sandwich," commented Dr. Steve Vance in a May 1, 2014 statement. Dr. Vance, of NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, went on to explain the weird moon's resemblance to the Blondie cartoon character's famous multi-layered sandwiches. The study, headed by Dr. Vance, provides new theoretical indications for the team's "club sandwich" model, originally proposed in 2013. The research appears in the journal Planetary and Space Science. Bringing Birth Chart Astrology Down To Earth. This the first of a series of articles in which I try to bring Astrology down to Earth, by explaining what each planet represents in us at a basic level. This article explains the Moon, which is one of the Ego planets, Sun and Saturn being the other two, understanding each in turn and learning to see them as sub-personalities that need to work together to make you feel secure, worthwhile and complete. An awareness of these different energies will help in the understanding of your inner core self which is needed before the process of integration can successfully occur.
