Galilean Moons of Jupiter Diagram

Galileo’s discovery proved the importance of the telescope as a tool for astronomers by showing that there were objects in space to be discovered that until then had remained unseen by the naked eye. More importantly, the discovery of celestial bodies orbiting something other than Earth dealt a blow to the then-accepted Ptolemaic world system, which held that Earth was at the center of the universe and all other celestial bodies revolved around it. Galileo’s Sidereus Nuncius (Starry Messenger), which announced celestial observations through his telescope, does not explicitly mention Copernican heliocentrism, a theory that placed the Sun at the center of the universe. Nevertheless, Galileo accepted the Copernican theory.



Beneath The Icy Crust Of Enceladus. The research paper written by scientists with the Cassini mission, published in the journal Science, suggests the presence of hydrogen gas. Hydrogen gas, that could potentially provide a chemical energy source for life, is pouring into the subsurface ocean of Enceladus from hydrothermal activity on the seafloor of this bewitching, distant moon-world. o follow the Moon waxing and waning throughout the different zodiac signs is an elegant way to be more aware of your own constant change in the emotional landscape and how your emotional outlook is coloring the perception of events and circumstances. The Moon is the fastest moving planet we observe in astrology and is known for her fickle nature. Every 2 ½ days there is a variation in the way we subtly feel and react from that gut level instinct. The Moon is representing our emotional filter and the way we perceive life. The position of the Moon in your personal chart is one of the most important points of an astrological reading. Earlier infrared data did not have sufficient resolution to separate MK 2 from Makemake's veiling glare. The astronomers' reanalysis, however, based on the more recent HST observations, indicates that much of the warmer surface spotted earlier in infrared light may simply be the dark surface of the companion MK 2.
