Some say Ireland is the land of rainbows. Maybe its because there is a lot of rain, maybe its because there are a lot of leprechauns.

If you chase the rainbow you may find its end. And as reward you'll find a pot of gold - or leprechaun headquarters.

Although there is certainly a poetry to the world when it's alive and full of people, there is simply nothing that can possibly compare to that same world when no one else is around. It is stripped of the extraneous energy and second hand emotion that occurs when you're lost in a crowd (even if that crowd is small). You're seeing it raw… bare. It's an otherworldly experience to say the least.

Now add sunrise to the mix. That's the time when the earth itself wakes up. Shades of understated grey give way to hues of lilac, violet, and lemon that simply don't exist later in the day. It is the visual equivalent of listening to an orchestra tuning up just before the performance of a lifetime.

This shot features a private boathouse along the main river of Perth. (If you've visited the area, you may know it well!)

At sunrise on this crisp winter morning, it appeared wise… knowing. A loan witness to this beautiful world at this extraordinary time of day, there at the end of that simple, weathered pier.

Baishi Mountain is located in Taiyuan county, west region of China's Hebei province. Its main ridge line is over 7,000 meters long and the highest peak is 2,096 meters high. The fog at high altitudes make the mountain a fairyland on Earth.

Planetary nebulae like the Helix are sculpted late in a Sun-like star's life by a torrential gush of gases escaping from the dying star. They have nothing to do with planet formation, but got their name because they look like planetary disks when viewed through a small telescope. With higher magnification, the classic "donut-hole" in the middle of a planetary nebula can be resolved. Based on the nebula's distance of 650 light-years, its angular size corresponds to a huge ring with a diameter of nearly 3 light-years. That's approximately three-quarters of the distance between our Sun and the nearest star.

The Helix Nebula is a popular target of amateur astronomers and can be seen with binoculars as a ghostly, greenish cloud in the constellation Aquarius. Larger amateur telescopes can resolve the ring-shaped nebula, but only the largest ground-based telescopes can resolve the radial streaks. After careful analysis, astronomers concluded the nebula really isn't a bubble, but is a cylinder that happens to be pointed toward Earth.

Located on Tanjung Aru, Kota Kinabalu, Sabah, Borneo, Malaysia, Shangri-La Tanjung Aru Resort is a man-made beach resort that gives a very great view of sunsets every single day. Shot on the rocky side of the small private beach provided by the resort over-viewing the Sunset Bar in the vicinity.
