Picture of the Day

As the Earth spins on its axis, the sky seems to rotate around us. This motion, called diurnal motion, produces the beautiful concentric trails traced by stars during time exposures.

Partial-circle star trails are pictured above over Oregon, USA last month. Near the middle of the circles is the North Celestial Pole (NCP), easily identified as the point in the sky at the center of all the star trail arcs.

The star Polaris, commonly known as the North Star, made the very short bright circle near the NCP.

Moon Games 

The Moon's measured diameter is around 3,476 kilometers (2,160 miles). But apparent angular size, or the angle covered by an object, can also be important to Moon enthusiasts. Angular size depends on distance, the farther away an object is, the smaller an angle it covers. Since the Moon is 400,000 kilometers away, its angular size is only about 1/2 degree, a span easily covered by the tip of our finger held at arms length, or a measuring tape held in the distance by a friend.

Far Above...

Where is your viewpoint in life?
Is it from the Mountain-top or from the Pit-beneath?

What would it be like to stand atop the tallest mountain on Earth? To see a full panoramic vista from there. Visible are snow peaked mountains near and far, tremendous cliffs, distant plateaus, the tops of clouds, and a dark blue sky.

Mt. Everest stands 8.85 kilometers above sea level, roughly the maximum height reached by international airplane flights, but much less than the 300 kilometers achieved by a space shuttle. Mt. Everest lies in the Himalayan mountains in the country of Nepal. In the native language of Nepal, the mountain's name is "Sagarmatha" which means "forehead of the sky."

Who says you are not wonderful?

Did You Know?

The human brain consists of more than 100 billion nerve cells (neurons) through which the brain's commands are sent in the form of electric pulses. These pulses travel at more than 400 km/h (250 mph), creating enough electricity to power a lightbulb. The brain consumes more energy than any other organ, burning up a whopping one-fifth of the food we take in.

It can process many operations at the same time (such as thinking, talking and walking at the same time). This is called parallel processing. I call it Multi-tasking!

It is estimated that the mental capacity of a 100-year old human with perfect memory could be represented by computer with 10 to the power of 15 bits (one petabit- i.e. 1,000,000,000,000,000). However, that represents just memory capacity, not the extremely complex processes of thought creation and emotions.

"I praise You because of the wonderful way You created me. Everything You do is marvelous! Of this I have no doubt."- Psalm 139:14

Castle & Sky

This strikingly beautiful picture was featured as the Astronomy Picture of the Day in the month of January 2007. It is a  picture of the brilliant Venus and a slender crescent Moon overlooking a small Spanish town, along with a well-lit Castle Almodovar.

Does it strike-up any scriptural image in your mind???

Let me know what you think!

Picture of the Day!

This picture taken on the 1st of October 2006 shows what the Earth looks like at night. Can you find your country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earth's surface, including the seaboards of Europe, the eastern United States, and Japan. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the orbiting DMSP satellites.
