It’s Full of Stars — One of the Densest Star Clusters Ever Discovered
This recently released photograph from the Hubble Telescope captures the spectacular glory of Messier 15 located about 35,000 light-years away. It might be hard to believe, but if you were to look up in the sky and locate the constellation Pegasus, this entire cluster of stars is located inside of it. It is one of the densest clusters of stars ever discovered. Via the ESA:
Both very hot blue stars and cooler golden stars can be seen swarming together in the image, becoming more concentrated towards the cluster’s bright centre. Messier 15 is one of the densest globular clusters known, with most of its mass concentrated at its core. As well as stars, Messier 15 was the first cluster known to host a planetary nebula, and it has been found to have a rare type of black hole at its centre.
Iceland’s Massive Dinosaur Rock
Located in North Iceland, in the Gulf of Húnaflói, stands a massive rock that looks like a grazing dinosaur called Hvítserkur. The spectacular structure is a natural formation on the landscape that adds an intriguing, mystical touch to the surrounding environment. In fact, legend has it that the colossal boulder was once a giant troll seeking to attack a neighboring abbey, but was petrified into a slab of stone when caught in the rising sun.
Whether one believes in folklore or not, it adds to the story of Hvítserkur, which used to be a volcano. The structure is the remains of a 15-meter-high volcano that has almost completely eroded away. Photographers both in and out of Iceland seek to capture shots of the beautiful, monumental rock.

Adorable Photos of Dogs Caught in Mid-Bath
Some look confused, others startled, but all of these incredibly cute dogs look just plain adorable. Wet Dogs is a series of portraits of dogs caught mid-bath. Bath time for dogs can be a vulnerable and messy experience as the expressions on their faces clearly communicate. These pooches are being photographed seconds before they shake the water off their fur.
Photographer Sophie Gamand’s Wet Dog series reveals another layer of the human-animal bond — one with shampoo mohawks and wet fur. The photographer wanted to capture the complex relationship between humans and their pets. Their is a lot of codependence between the two and Gamand wants others to see dogs for what they are: more than just animals, they are life companions.
Rare Ice Disks
Although extremely rare, ice disks, also known as ice circles, do indeed appear naturally from time to time when conditions are perfect. Above are a few examples of people who have been lucky enough to stumble onto one while holding a camera.
Ice discs form on the outer bends in a river where the accelerating water creates a force called ‘rotational shear’, which breaks off a chunk of ice and twists it around. As the disc rotates, it grinds against surrounding ice — smoothing into a circle. A relatively uncommon phenomenon, one of the earliest recordings is of a slowly revolving disc was spotted on the Mianus River and reported in a 1895 edition of Scientific American.
The Man Who Had an Iron Spike Go Completely Through his Head and Lived — The Sad and Bizarre Story of Phineas Gage
Phineas Gage is the most famous person to have survived severe damage to the brain. His accident illustrates the first medical knowledge gained on the relationship between personality and brain damage. After his injury, he turned into a completely different person - an entirely new personality.
A well-liked and successful construction foreman, Phineas Gage was contracted to work for the Rutland & Burlington Railroad in Vermont. In September 1848 while Gage was preparing a railroad bed, an accidental explosion of a charge he had set, blew a 13-pound tamping iron straight through his head.
The tamping iron was 1 1/4 inches in diameter. It went in point first under his left cheek bone and completely out through the top of his head, landing about 25 to 30 yards behind him.
Despite his torn scalp and fractured skull, Gage remained lucid and rational during the ride to the hospital and was even able to speak. Cage not only survived losing a chunk of his brain, he was able to returned home in only 10 weeks. Unfortunately, Gage’s recovery was not a complete success.
The once friendly and well-liked man became mean, impatient, rude, and seemed to have lost any empathy toward others. Those who knew him before the accident said he was “no longer Gage.”
Cage worked in several livery stables for the next ten years until 1859 when his health began to fail. He moved to San Francisco to live with his mother and began to experience the epileptic seizures that would lead to his death in 1860. The tale is heart-breaking.
His story is still standard content in medical, anatomy, and psychology textbooks. His skull and the tamping iron are currently on display in the Warren Museum Exhibition Gallery in Boston, Massachusetts.
