Aurora, A Mysterious Light In The Night Sky

An aurora is a mysterious and unpredictable display of light in the night sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.  Auroras in the northern hemisphere are called aurora borealis or northern lights, and in the southern hemisphere aurora australis, or southern lights.

Auroras can appear as long, narrow arcs of light, often extending east to west from horizon to horizon. At other times they stretch across the night sky in bands that kink, fold, and swirl, or even ruffle like curtains. They can spread out in multi-colored rays usually green but often showing shades of blue and red, and sometimes yellow or white.

Auroras are caused at altitudes of 100 to more than 400 km (60 to more than 250 miles) by fast-moving energetic particles (electrons and protons) from the Earth’s magnetosphere, the region of space controlled by Earth’s magnetic field. When a large number of energetic particles enter the upper atmosphere and bombard the gases in the atmosphere, causing them to emit enough light for the eye to detect, giving us beautiful auroral displays.

The color of the aurora depends upon how fast the electrons are moving, or how much energy they have at the time of their collisions with upper atmosphere gased (Oxygen and Nitrogen). High energy electrons cause oxygen to emit green light (the most familiar color of the aurora), while low energy electrons cause a red light. Nitrogen generally gives off a blue light. The blending of these colors can also lead to purples, pinks, and whites. The different shapes of auroras are a mystery that scientists are still trying to unravel. The shape seems to depend on where in the magnetosphere the electrons originate, what causes them to gain their energy, and why they dive into the atmosphere.

206 Stones Removed From Man’s Kidney

A group of doctors under supervision of urologist Ravindra Patil from Patil Lithotripsy and Nursing Home, Gulbarga, India, have removed as many as 206 stones from the left kidney of Mr.Nawaz, a 41-year-old man, through the surgery employing the Percutaneous Nephrolithotomy technique on 20 February 2015.  


"Removed stones are varied size from 8 mm to 15 mm. Nawaz was discharged from hospital 48 hours after the operation." said Dr.Patil.

Dr. Patil hopes to get an entry in the Guinness World Records for the medical feat. “The world record of removing the highest number (more than 130) stones of different sizes from the kidney of a patient at OPEC Hospital in Raichur a couple of years ago is held by Deepak Bolbunde, ” he said.

The patient was awake throughout the three-hour-long surgery and his blood loss was minimal. He was neither given any fluids nor blood transfusion, Dr. Patil said.Mr. Nawaz, a tailor and father of three, had undergone a surgery 10 years ago in the Government General Hospital in Gulbarga to remove stones from his right kidney. He hails from Rangampet in Surpur taluk of Gulbarga district. Dr. Patil said: “Keyhole surgery is performed by making a small opening in the skin. With the help of an image intensifier guidance system, an entry is made into the affected kidney and with the help of a nephroscope, the stones are picked up one by one and removed through a port.” Dr. Patil

On his website, Tobbe explains: "The bolts are from an old farm in the heart of a the area Bergsladen in Sweden. I found them in a barn. They had been lying there for a long time and they might well have continued to lie there until they had rusted away and returned to their original mineral form. The bolts reminded me of human forms, and I felt they had something to tell. I heated them, forged, bent and twisted. I tried to create relations, meetings and situations and suddenly stories emerged about sorrow, joy, pain, warmth and humour. A kind of poetry was created, hence the title."

Tianzi Mountains, China

Tianzi Mountains, located in Zhangjiajie in the Hunan Province of China, are pillar like structures characterized by old, weathered sandstone mountain-peak remnants, some in the form of massive blocks and some in the form of freestanding sandstone obelisks, or towers.

'Tianzi' which means 'Son of Heaven' is named after a farmer who lived in this area. The highest peak here is 1,262 meters (about 4,140 feet) above the sea level. Unsurprisingly, this is the place that served as inspiration to the floating mountains featured in Avatar.

The base of these peak structures has a bit of limestone bedrock which has produced 'Karst caves' as a result of aeons of water erosion. In addition to the stunning landscape, the region is also known for the number of endangered plant and animal species that inhabit it, such as the Chinese giant salamander, Asiatic wild dog, Asiatic black bear, and the Clouded leopard.

Visitors can take a ride using cable car service that travel horizontally high above the mountains to have glimpse of peaks.
