I took this photo from the top of "Siegessäule", facing the skyline of Berlin, Germany.

Skógafoss is a waterfall situated on the Skógá River in the south of Iceland at the cliffs of the former coastline and is one of the biggest waterfalls in the country with a width of 25 m (82 feet) and a drop of 60 m (200 ft).

According to legend, the first Viking settler in the area buried a treasure in a cave behind the waterfall but I couldn't find it...

This composite image combines a near-infrared view from the Hubble Space Telescope, an infrared view from the Spitzer Space Telescope, and an X-ray view from the Chandra X-ray Observatory into one multi-wavelength picture.

It features the spectacle of stellar evolution: from vibrant regions of star birth, to young hot stars, to old cool stars, to seething remnants of stellar death called black holes. This activity occurs against a fiery backdrop in the crowded, hostile environment of the galaxy's core, the center of which is dominated by a supermassive black hole nearly four million times more massive than our Sun. Permeating the region is a diffuse blue haze of X-ray light from gas that has been heated to millions of degrees by outflows from the supermassive black hole as well as by winds from massive stars and by stellar explosions. Infrared light reveals more than a hundred thousand stars along with glowing dust clouds that create complex structures including compact globules, long filaments, and finger-like "pillars of creation," where newborn stars are just beginning to break out of their dark, dusty cocoons.

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.

Taken at the beautiful Moraine Lake, just outside of Banff, Canada. This lake is also close to Lake Louise, but is often missed since the hype to see Lake Louise is stronger. Moraine is far more beautiful in my opinion. Turquoise water and cascading mountains all around.

At the heart of a Belgian forest, by a bright and slightly foggy morning, i captured this particular atmosphere that i miss as a citizen.
