This was taken at Theater of the Sea, a marine animal park in Islamorada, Florida in 1997. Although I do not believe in the Zoo or the Aquarium, I found the curiosity and affection between these two animals adorable.
I hope that one day soon all creatures will be left where they belong instead of being confined or condemned for human enjoyment. It's just wrong :(
Earth's upper atmosphere—below freezing, nearly without oxygen, flooded by UV radiation—is no place to live. But last winter, scientists from the Georgia Institute of Technology discovered that billions of bacteria actually thrive up there. Expecting only a smattering of microorganisms, the researchers flew six miles above Earth's surface in a NASA jet plane. There, they pumped outside air through a filter to collect particles. Back on the ground, they tallied the organisms, and the count was staggering: 20 percent of what they had assumed to be just dust or other particles was alive. Earth, it seems, is surrounded by a bubble of bacteria.
It’s Alive! & Airborne: In the midst of airborne sea salt and dust, researchers from Georgia Tech unexpectedly found thousands of living fungal cells and bacteria, including E. coli and Streptococcus.
Scientists don't yet know what the bacteria are doing up there, but they may be essential to how the atmosphere functions, says Kostas Konstantinidis, an environmental microbiologist on the Georgia Tech team. For example, they could be responsible for recycling nutrients in the atmosphere, like they do on Earth. And similar to other particles, they could influence weather patterns by helping clouds form. However, they also may be transmitting diseases from one side of the globe to the other. The researchers found E. coli in their samples (which they think hurricanes lifted from cities), and they plan to investigate whether plagues are raining down on us. If we can find out more about the role of bacteria in the atmosphere, says Ann Womack, a microbial ecologist at the University of Oregon, scientists could even fight climate change by engineering the bacteria to break down greenhouse gases into other, less harmful compounds.

Calment was born in Arles, France on February 21, 1875. Her lifespan has been documented by scientific study.
Proof that Keith Richards can still get it up.
Io, Europa, Ganymede & Callisto (i.e: the four moons of jupiter in photo order)Surface features, such as furrows, grooves and impact craters are illustrated on this 360 degree view of the moon. The best imagery from NASA's Voyager 1 and 2 and Galileo spacecrafts were used to create it. Galileo Galilei discovered it in 1610.
Could Ganymede, Europa and/or Callisto support life?
The Jupiter Icy moons Explorer – JUICE is the first Large-class mission chosen as part of ESA’s Cosmic Vision 2015-2025 program. It will be launched in 2022 from Europe’s spaceport in Kourou, French Guiana, on an Ariane 5, arriving at Jupiter in 2030 to spend at least three years making detailed observations. Jupiter’s diverse Galilean moons – volcanic Io, icy Europa and rock-ice Ganymede and Callisto – make the Jovian system a miniature Solar System in its own right.
With Europa, Ganymede and Callisto all thought to host internal oceans, the mission will study the moons as potential habitats for life, addressing two key themes of Cosmic Vision: what are the conditions for planet formation and the emergence of life, and how does the Solar System work?
