Taken at the Singapore Botanic Gardens, at the rim of a pond in the middle of the gardens. I've been trying to get a macro shot of a dragonfly's face for the past couple of weeks at that pond, but it is tough because they tend to look out on the water, not back toward where I can perch myself. They also fly away if you're not careful. For some reason, perhaps because it had just rained, this particular dragonfly took very little notice of me and let me get a decent shot-- this is perhaps the best I can do with the current equipment I am using.

A 3-light-year-long pillar, bathed in the glow of light from hot, massive stars to the top of the image. Scorching radiation and fast winds (streams of charged particles) from these stars are sculpting the pillar and causing new stars to form within it. Streamers of gas and dust can be seen flowing off the top of the structure.
Nestled inside this dense structure are fledgling stars. They cannot be seen in this image because they are hidden by a wall of gas and dust. Although the stars themselves are invisible, one of them is providing evidence of its existence. Thin puffs of material can be seen traveling to the left and to the right of a dark notch in the center of the pillar. The matter is part of a jet produced by a young star. Farther away, on the left, the jet is visible as a grouping of small, wispy clouds. A few small clouds are visible at a similar distance on the right side of the jet. Astronomers estimate that the jet is moving at speeds of up to 850,000 miles an hour. The jet's total length is about 10 light-years.
Composed of gas and dust, the pillar resides in a tempestuous stellar nursery called the Carina Nebula, located 7,500 light-years away in the southern constellation Carina.
I took this shot during a balloon ride that my wife and I took during our anniversary. The morning sun was at our back as the pilot descended to skim over a cornfield. I thought that the shadow of our balloon was a nice contrast against the green of the cornfield. The natural color of the corn stalks was a little dull and so I adjusted the color and shadow levels with Picasa.
The form of the coastline around Durdle Door is controlled by its geology--both by the contrasting hardnesses of the rocks, and by the local patterns of faults and folds.The arch has formed on a concordant coastline where bands of rock run parallel to the shoreline. The rock strata are almost vertical, and the bands of rock are quite narrow. Originally a band of resistant Portland limestone ran along the shore, the same band that appears one mile along the coast forming the narrow entrance to Lulworth Cove. Behind this is a 120-metre (390 ft) band of weaker, easily eroded rocks, and behind this is a stronger and much thicker band of chalk, which forms the Purbeck Hills. These steeply dipping rocks are part of the geological structure known as the Lulworth crumple, itself part of a broader monocline (a kinked type of geological fold) produced by the building of the Alps during the mid-Cenozoic.
