A volcano in Indonesia produces lava that looks BLUE!

Though the molten sulfur looks red in daylight, during the night, the blue flames that reach heights of 5 meters (16 feet) are highly visible. The sulfur, which is right around its melting point at 115°C (240 °F), is pumped away from the volcano so it can cool and be collected by miners for 680 rupiahs per kilogram (about 2.5 cents per pound).

A 2-year-old albino kangaroo has been spotted in Canberra’s Namadgi National Park. Albino kangaroos in the wild usually don’t survive because they stand out and become an easy target for predators. Albino animals also have a genetic predisposition towards sight and hearing issues, making life in the wild almost impossible—but Rene(e), which is always surrounded by its mob, has survived against all odds.

These beautiful birds are called purple-crowned fairy wrens, endemic to northern Australia. The picture was taken by ornithologists (bird banders) studying the birds as part of population monitoring in Australia. The way they are holding them is called "photographer's grip" which gently secures the legs while keeping the rest of the bird free. Handling time is generally very short.

The Bali myna (Leucopsar rothschildi) is one of the rarest birds in the world. Thanks to poaching, their wild population hit an all-time low of just six individuals in 2001, but their numbers have since increased to around 50 wild mature birds. And just this month, the Bali Starling Conservation Project, which is home to 100 Bali mynas, has celebrated the birth of four healthy chicks to add to their breeding program. ...

Meet the green jumping spider (Mopsus mormon), Australia’s largest—and perhaps cutest—jumping arachnid. These spiders hunt in the day time, moving fast to attack their prey, and camouflaging against green leaves. If you see one, leave it alone. Although their bite won’t kill you, it’s extremely painful.

The Monticello Dam holds back Lake Berryessa in Napa County, California, USA. The morning glory spillway associated with the dam is the largest in the world; it is a funnel-shaped outlet that allows water to bypass the Monticello Dam when it reaches capacity (1370 m³/s).

The Glory Hole is located about 61m from the dam; the distance from the funnel to the exit point - which is situated in the south side of the canyon - is about 213m. The outside diameter is 22m, slowly narrowing to 8.5m at the exit.

Water spills over the lip of the Glory Hole when the lake reaches 1,976,037,908 cubic metres (1,602,000 acre-feet). The spillway is designed to handle a maximum of 1,370,319 litres of water per second (362,000 gallons of water per second); this ha ...
