Astronomical shadows…

May 28, 2008 · 1 Comment

The term eclipse is derived from the ancient Greek noun “ékleipsis“, “I cease to exist.”

A lunar eclipse is an astronomical event that occurs whenever the Moon passes through some portion of the Earth’s shadow. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle.

Hence, there is always a “full moon” the night of a lunar eclipse.

Earthshine

February 21, 2008 · 12 Comments

My friend John Cara sent me this morning a most spectacular photo of the “Lunar Eclipse.”

Lunar eclipses can only occur during a ‘Full moon’ phase. 
Because the Earth casts a shadow larger than the apparent diameter of the moon and Earth’s illuminated atmosphere extends beyond it’s surface, even ‘total’ Lunar eclipses have areas of greater and lesser shadows. The Earth casts it’s central shadow, which is darkest, in a confined area, while it’s partial shadow is cast over a more extended area. Most ‘total’ eclipses of the moon have parts of the lunar surface covered in only the partial shadow of Earth so parts of the moon appear considerably brighter than other parts.

The Earth’s atmosphere casts ‘Earthshine’ which will further illuminate the moon to some extent even during a total lunar eclipse.
On these occasions, “Rays”, the lines radiating from major lunar craters are best illuminated and provide striking detail to the observer.

…call to Vespers.

February 20, 2008 · Leave a Comment

A true call to “vespers” was tonight’s “Full Lunar Eclipse”, an amazing flying color!
The moon appeared to be red because the
only light shining on it comes from dim sunlight filtered red by the Earth’s
atmosphere and refracted into the Earth’s shadow.

George Nguyen and Ion Iftimie catalogued the eclipse’s progression from George Washington University in Washington, DC.,
between 7:30 and 8:30 p.m. ET. They used two digital cameras at 10x zoom.

Art Statement

When I take the time to look and to really see and to apply my "foolish" imagination, there are worlds within worlds within worlds to be discovered.

When I allow my eyes to be excited and fascinated and pleased at what they see, I begin a journey, inventing a path to the place I choose to go; and magic happens!
