Iceland: Jokulsarlon lagoon. A "popular" destination on the south coast of the island. As the glacier melts, a lake is formed and icebergs slowly make their way to the ocean, connected by a short river.

One of my favourite pictures from our trip to Iceland in September 2014. I have not manipulated the image much. To save the flare from that beautiful sunset.

NASA and ESA are celebrating the Hubble Space Telescope's silver anniversary of 25 years in space by unveiling some of nature's own fireworks — a giant cluster of about 3,000 stars called Westerlund 2. The cluster resides inside a vibrant stellar breeding ground known as Gum 29, located 20,000 light-years away in the constellation Carina. The comparatively young, 2-million-year-old star cluster contains some of our galaxy's hottest, brightest, and most massive stars. The largest stars are unleashing a torrent of ultraviolet light and hurricane-force winds that etch away the enveloping hydrogen gas cloud. This creates a fantasy celestial landscape of pillars, ridges, and valleys.

On Wednesday I spent 14 hours and drove around 700 miles chasing storms through Kansas and Oklahoma. The "cap" prevented many of the storms from producing much, but we ended the night with a breathtaking sunset that lasted over an hour! What a sight! This is a photo I took near Enid, Oklahoma while we were enjoying the show.

I was pleased with the clarity of this shot despite the fact that it was taken through the window of a moving helicopter. The white line you see on the sides of the lake is the original water line. Lake Mead is currently down 91 feet.
