Sri Parthasarathi Brahmothsavam 2017 : day 4 - Chandra Prabhai

Today,  15th Apr 2o17  is day 4 of  Brahmothsavam of  Sri Parthasarathi -  it was the radiant Surya prabhai in the morning and the pleasant ‘Chandra prabhai’ in the evening.

The moon is the easiest celestial object  found  in the night sky — when it is there. One that is visible to naked eye.  Earth's only natural satellite hovers above us bright and round until it seemingly disappears for a few nights. The rhythm of the moon's phases has guided humanity for millennia — for instance, calendar months are roughly equal to the time it takes to go from one full moon to the next. Moon phases and the moon's orbit are mysteries to many. For example, the moon always shows us the same face. That happens because it takes 27.3 days both to rotate on its axis and to orbit Earth. We see either the full moon, half moon or no moon (new moon) because the moon reflects sunlight. How much of it we see depends on the moon's position in relation to Earth and the sun.

Moon’s  influence on Earth's cycles, notably tides, has been charted by many cultures in many ages. The moon moderates Earth's wobble on its axis, leading to a relatively stable climate over billions of years.  The Moon (Lunar) is one of the largest natural satellites in the Solar System, and, among planetary satellites, the largest relative to the size of the planet it orbits (its primary). The Moon is thought to have formed approximately 4.5 billion years ago, not long after Earth. There are several hypotheses for its origin; the most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a Mars-sized body called Theia.

திருவல்லிக்கேணி பிரம்மோத்சவத்தில் நான்காம் நாள் காலை பெருமாள் சூர்யப் பிரபையிலும்;   மாலைகுளிர்ச்சியான வெள்ளி நிறமுடைய சந்திரப் பிரபையிலும்
புறப்பாடு கண்டு அருளினார்.

சந்திரன் குளிர்ச்சியானவன்முழுமதி மிகவும் சந்தோஷத்தை தர வல்லது. சந்திரனுக்கு நிலாஅம்புலி  என பெயர்கள் உண்டு. நிலவை  நோக்கி  கைநீட்டி, தன் குழந்தையுடன் விளையாட வருமாறு அம்புலியை  ழைக்கும்பருவம் - அம்புலிபருவம். பெரியாழ்வார் கண்ணனை வளர்க்கும் பருவத்தில்,  தனது  'பெரியாழ்வார் திருமொழியில்  'பத்து பாடல்களில்சந்திரனை வளரும் அழகு  கண்ணனுடன்’  விளையாட அழைக்கிறார். மேகத்தில் மறையாமல் விளையாட  வரச் சொல்லி  "மஞ்சில் மறையாதே மாமதீ மகிழ்ந்தோடி வா" என்கிறார்.

More on Moon :  A tiny moon of Saturn has most of the conditions necessary for life, Nasa announced  couple of days back, unveiling a discovery from an underground ocean that makes the world a leading candidate for organisms as humans know them. Scientists stressed that the discovery on a moon named Enceladus is not evidence that life has in fact developed on another world, but they have managed to establish the existence of the water, chemistry and energy sources that are necessary for it.

“We now know that Enceladus has almost all of the ingredients that you need to support life as we know it on Earth,” said  a project scientist who said the finding essentially confirmed vents on the moon’s seafloor. Another one  involved in the project added,   the discovery showed that the moon’s ocean contained a potential chemical feast for microbes. “We have made the first calorie count on an alien ocean.” Beneath its frozen surface, Enceladus has a saltwater ocean, and the hydrogen – produced in a reaction between heated water and rocks – indicates that the moon has active energy sources, possibly akin to the undersea vents that teem with life on planet Earth.

Interesting !!
