Volunteers try to keep alive some of the hundreds of stranded pilot whales after one of the country's largest recorded mass whale strandings, in Golden Bay, at the top of New Zealand's south island, February 10, 2017. Volunteers in New Zealand managed to refloat about 100 surviving pilot whales on Saturday, February 11, 2017 and are hoping they will swim back out to sea after more than 400 of the creatures swam aground at a remote beach.

A masked Bulgarian dancer takes part in the second competition day of the 24th International Festival of Masquerade Games “Surva” in the town of Pernik, Bulgaria Saturday, January 31, 2015. Some 5,000 people are expected to take part in the three-day festival devoted to an ancient Bulgarian pagan rite. Surva is performed by costumed men, some in sheepskin, or other colorful garments, bells and masks, who walk around and dance to scare away the evil spirits, in hope to provide a good harvest, health, fertility, and happiness.

Each day as we look in the mirror, we think that we know ourselves. We are used to the image that we see before us, but the mirror can show us much more than we ever hoped to see. Sometimes it only shows basic emotions, while at other times it can highlight the deepest crevices of our soul. If you wish, in the reflection of the mirror you can see your deepest thoughts, masks that you wear every day, your desires, and of course the people that you think about. But are you brave enough to look deep within your soul? Will you dive headlong or shy away from your true image? Those that will muster up the courage necessary will realize it was well worth the effort. (Photo by Devin Mitchell)

“Are you here for the Winery Tour?” This is a Western Grey Kangaroo caught lounging in the wineries of the Adelaide Hills in South Australia. This past Autumn has been a spectacular time for wildlife viewing and I got lucky to spot this guy while mountain biking in the hills. Such a funny stance it just begs the question... Have you been drinking? ...and or... Are you here for the Winery Tour? Such a spontaneous moment I figured it would be perfect for an entry. I hope you like it! Cheers. Photo location: Adelaide Hills, South Australia, Australia. (Photo and caption by Greg Snell/National Geographic Photo Contest)

“The V-30 Warhawk was designed by Blackshaw Avionics as a long-range fighter and was primarily used by the Arcadian Air Force for escort duties. The plane pictured is the “Spirit of Freedom” and was one of the four planes that escorted the Arcadian Royal Airship during and after the Great War. The three other fighters were the “Spirit of Hope”, the “Spirit of Justice” and the “Spirit of Destiny”. All pilots were hand-picked by the Head of Airborne Forces and included some of the very finest pilots in the Kingdom. The crew consisted of one pilot and one gunner although both cabins were fitted so that if either crew member was killed the other could take over their duties. Each Warhawk was fitted with four Haverlock “Banshee” engines and four 24mm machine guns”. (Photo and comment by Jon Hall)

An employee holds a plant with roots at the Plant Advanced Technologies (PAT) company greenhouse in Laronxe near Nancy, Eastern France, June 19, 2015. The farmers employed at the site in Laronxe are growing plants in a special way with a view to “milking” them for use in medicines, cosmetics and agrochemicals. Several major brands, including Germany's BASF and France's Chanel, have teamed up with Plant Advanced Technologies (PAT) in the hope of securing privileged access to the so-called “biomolecules” it extracts through the use of a patented technique.

Usually, we can only expect mischief from a group of overactive students. However, three talented students from Germany have amazed us with their dedication for beautifying their hometown. The electrical towers were always considered to be big ugly things. Most of the time, the electrical towers look awkward and completely ruin the beautiful landscape behind them. Nevertheless, the young minds have thought of a way to turn these towers into multicolored lighthouses, which immediately draw the attention of all the passersby and look as if they were brought here from a different world. All that was needed to achieve this was a little bit of imagination, colored plastic, and some spare time. Let us hope that this is only the beginning of the journey of these young artists.
