Corvus Eye Observatory, Athens & Syros, Greece: Total Solar Eclipse

Our Srar

Our Star
Its image is mesmerizing - out of this world - through a solar telescope...
A star full of life, willing to talk to you, sometimes through its carefree fairies (prominences), dancing at the disk limbs or its black halos (sun spots) and serpentine figures (filaments), crawling on its surface making any observer gazing at them in awe...

A fascinating spectacle changing every day without repeating the magic of the previous day...
This is what makes it a unique, worth observing celestial object by amateur and professional astronomers alike....

Total Solar Eclipse, Queensland,Australia 2012

Many thanks to Panasonic Team. Here's a few snapshots of the total solar eclipse, Australia 2012 from the life by "Solar Power 1" and "Solar Power 2".... It was a great transmission for all of us that we were not lucky to be there..!!

OUR STAR....

The star around which the Earth revolves, and the gravitational center of the Solar System; it lies about 270,000 times closer to us than the next nearest star. The Sun is a solitary, yellow dwarf star of spectral type G2 (see G star) that has been on the main sequence for about 4.6 billion years.

The Sun consists largely of hydrogen (71% by mass) and helium (27%), with much smaller amounts of heavier elements. It puts out 400 trillion trillion watts of energy, produced by the fusion of hydrogen to helium by the carbon-nitrogen cycle in its core. The Sun is 109 times wider than the Earth. It spins on its axis with a period that varies from 25 days at the equator to 33.5 days near the poles.

The visible surface, or photosphere, is surrounded by the chromosphere and, beyond this, the corona.
