Behold, our wondrous blue planet. This is the Earth’s atmosphere and its moon as seen from the International Space Station. Just look at the Earth’s atmosphere in all of its glory. This layer of gas surrounds our planet and is retained by the Earth’s gravity. Although the moon appears to be right outside our atmosphere, it is actually 238,900 miles away from us. Most humans will never get the chance to see this view for themselves, but at least we get to enjoy this stellar photography. Thanks to our friends @Tech for the sweet post! #science #earth #space #tech #travel #adventure #technology #awesome #bestof

🌞 This stunning photograph was taken in the Serengeti, an ecosystem and geographical region in East Africa. Of the approximately 70 large mammals found in the region, the giraffe is one of the easiest to spot due to the fact that it is the tallest living terrestrial animal. To account for its towering height, the giraffe has developed several evolutionary adaptations, many of which involve its circulatory system. Giraffes are so tall that their hearts must generate almost double the blood pressure required for a human to maintain blood flow to the brain. When the animal lowers its head, blood rushes down fairly unopposed, and a rete mirabile (a complex of arteries and veins) in the upper neck prevents excess blood flow to the brain. When it raises its head, blood vessels constrict and direct blood into the brain so that the animal does not faint. Talk about a head rush!

Some of us just need a little personal space, okay? 🌳✋ A few tree species experience a phenomenon called "crown shyness" in which the crowns of trees do not touch, resulting in a canopy with tight gaps. There are many hypotheses for why this occurs. One hypothesis states that the "behavior" might hinder the spread of leaf-eating insect larvae. Another contends that the interlocking of branches leads to “reciprocal pruning” of adjacent trees as trees collide with each other during winds, resulting in what looks like crown shyness. A prominent hypothesis is that the phenomenon involves a photoreceptor-mediated shade avoidance response in which trees detect their encroaching neighbors and direct growth away from them. These camphor trees (Dryobalanops aromatica) were found in the Kepong Forest Reserve in Malaysia. Tag a friend who’s always up in your personal space!

☃️🔷 Lake Baikal is a continental rift lake in Russia, located in southern Siberia, that holds some impressive titles. To start things off, it is the largest freshwater lake by volume in the world, containing 22–23% of the world s fresh surface water. Lake Baikal is also the world’s deepest lake, with a maximum depth of 1,642 m (5,387 ft.). The records don’t stop there: the freshwater lake is also considered to be the planet’s oldest lake, having been created roughly 25 million years ago. Records aside, Lake Baikal is renowned for having incredibly clear and beautiful ice that attracts visitors in the wintertime. When the lake freezes, huge shards of ice form, resulting in the magical phenomenon of turquoise ice. Tag someone you’d take to see the turquoise ice of Lake Baikal!

Imagine you’re a photographer in the heart of Africa*. You see a beautiful Lion alone, so you think to drive up real close & personal. Moments after stepping out of your cruiser and setting up the camera, the lion pounces and rushes towards you. Do you, A) run as fast as you can? Or B) take the photograph of a lifetime? Well luckily for @atifsaeedfineartphotography, he managed to get this chilling photograph and survive to tell the tale. (*Editorial correction)

You like groovin’ to get in the mood? So does the peacock spider! These male jumping spiders in the Maratus genus really like to put on a show for their possible mate, lifting their brightly colored tail flaps into the air and kicking their legs up like a Rockette during the holiday season. They also use their legs to drum up a sick beat, thumping on the ground (and even their conquest’s head) in order to get the point across. Also, if the female is dissatisfied with the male’s dancing, she’ll sometimes straight up eat him, which is a practice that we believe should be instated in every club in the world. Also, you can’t tell from this photo, but peacock spiders are teeny tiny, with the biggest getting to be about ¾ of a centimeter (⅓ of an inch). They’re also incredibly venomous, but the peacock spider has such a small jaw that it couldn’t possibly pierce its fangs into a chunk of human.

Using a 3D-printer, a group of high-school students was able to build a fully-functional prosthetic arm for an eight-year-old-girl named Hope. The prosthetic arm only cost $30, and it is pink, purple and white, because those are Hope’s favorite colors. "The more that she has it and works with it she ll figure out what she can do, or what it will help her be able to do,” said Hope’s mother, Kelley. Hopefully this is a step towards making prosthetics more available for everyone. Thanks @tech for sharing this awesome story. #tech #future #awesome #bestof

The most heavy metal chicken of them all! 🤘🐔 The Ayam Cemani is a rare and unusual breed of chicken from Java, Indonesia, famous for its black coloration that is more than skin-deep. The breed has a dominant gene that causes hyperpigmentation, making the bird completely black – from feathers to internal organs. Even their beaks, meat, and bones appear black. This strange occurrence is called ‘fibromelanosis,’ and was studied by a research team led by Leif Andersson, a Swedish geneticist at Uppsala University. The team concluded that this form of fibromelanosis is caused by a mutation that affects how pigment-producing cells travel during the early stages of development. On the island of Java, the Ayam Cemani is a fowl with elevated status, used in rituals perhaps as long ago as the 12th century.

Rock and roll? Well, almost. 🌬️ This photo comes to us courtesy of @arbylipmanphoto, and shows one of the famous sailing stones of the Racetrack Playa. The Racetrack, one of California’s most surreal sights, is a dry lakebed (playa) located in Death Valley National Park best known for its puzzling geological mystery. Scattered across the playa are hundreds of dolomite and syenite rocks – ranging from a few hundred grams to as much as 320 kilograms – that appear to have been pushed across the surface, often leaving behind trails that can stretch for hundreds of meters. To investigate the phenomenon, a research team led by Scripps Institution of Oceanography, UC San Diego, paleobiologist Richard Norris studied the famous rocks and their movements by installing a weather station and fitting 15 rocks with motion-activated GPS units. Due to the fact that the stones can sit for a decade or more without moving, the team then waited for what one of the co-authors described as “the most boring experiment ever.” Thankfully, the researchers did not have to wait too long for an answer to the mystery. On a field visit in December 2013, Norris and others arrived in Death Valley to discover that the Racetrack was covered with a shallow pond. Shortly after, the rocks began moving before them. Their research shows that rock movement requires a rare combination of events. First, the playa fills with water deep enough to allow the formation of floating ice during cold winter nights, but shallow enough to expose the rocks. As nighttime temperatures drop, the pond freezes to form thin sheets of ice that must be thick enough to maintain strength. On sunny days, the ice melts and breaks up into floating panels, which light winds drive across the playa pool. The ice sheets then push rocks in front of them, and the moving rocks leave trails in the soft mud bed below. Now you know!

🍭👽 This alien landscape is actually a sample of iridescent goethite crystals photographed at the Natural Science Museum of Álava (MCNA) in Vitoria, Spain. Goethite is typically a reddish-brown or yellowish-brown mineral consisting of oxyhydroxide iron, and it is the main component of rust. Although it is normally a dark, uninspiring mineral, rainbow-like specimens from a selection of special locations around the world (such as Munday s Hill Quarry in England and the Filón Sur Mine in Spain) are prized for their marvelous, iridescent crystal growths.

🌈 This multi-colored beauty is a lilac-breasted roller (Coracias caudatus), an African bird famous for its bright plumage. Found throughout sub-Saharan Africa and the southern Arabian Peninsula, these birds prefer environments like woodlands and savanna that offer high vantage points from where they can scout out ground-dwelling prey like insects and small vertebrates. They are especially abundant in Kenya, where they are considered to be the unofficial national bird. The lilac-breasted roller pictured above was spotted in South Luangwa National Park, Zambia.
