Earth is 4.5 trillion years old. It’s about 8,000 miles equatorial in diameter. It weighs 6,600,000,000,000,000,000,000 short tons. Surface area is 196,800,000 square miles. Earth travels through space at 66,700 miles per hour.  The crust is about 5 miles deep. Highest Point is Mt Everest 29, 028 above sea level. Lowest Land Point Dead Sea 1,302 below sea level. The word ‘Earth’ means land or ground.

6 billion humans and 10 million different species call it home. Nearly 7,000 different languages are spoken on it. 11 percent of the earth’s surface is used to grow food. 7 continents. 3158 cities. 5 oceans.

A senator of Wisconsin founded Earth Day and the day is credited for creating the environmentalism movement.

The following photos reveal the largeness of wonder that is our adored planet, and our profound luckiness to be here at this time, to see images from such an incredible and rare perspective.

Cumulonimbus Cloud

High above the African continent, tall, dense cumulonimbus clouds, meaning ‘column rain’ in Latin, are the result of atmospheric instability. The clouds can form alone, in clusters, or along a cold front in a squall line. The high energy of these storms is associated with heavy precipitation, lightning, high wind speeds and tornadoes.

This other worldly landscape is actually Dagze Co, one of many inland lakes in Tibet. In glacial times, the region was considerably wetter, and lakes were correspondingly much larger, as evidenced by the numerous fossil shorelines that circle the lake and attest to the presence of a previously larger, deeper lake. Over millennia changes in climate have resulted in greater aridity of the Tibetan Plateau.

African fires of 2002. The fires are shown as tiny particles with each particle depicting the geographic region in which fire was detected. The color of a particle represents the number of days since a sizable amount of fire was detected in that region, with red representing less than 20 days, orange representing 20 to 40 days, yellow representing 40 to 60 days, and gray to black representing more than 60 days.

What’s the Earth without the sun?  Dark and chilly.  2 mind blowing images of the sun, new from NASA, we couldn’t resist including here.  This is the sun heating and cooling, what is does best.

THE SUN

An extreme ultraviolet image of the sun taken by Space Dynamics Observatory on March 30, 2010. Reds are relatively cool (about 107,540 Fahrenheit); blues and greens are hotter (greater than 1.8 million Fahrenheit)
