Over the Top
Explanation: The central bulge of our Milky Way Galaxy rises above a sea of clouds in this
ethereal scene. An echo of the Milky Way's dark dust lanes,
the volcanic peak in foreground silhouette is on France's
RĂ©union Island in the southern Indian Ocean. Taken in February, the photograph was voted the winner of the
2014 International Earth and Sky Photo Contest's Beauty of the Night Sky Category. This and other winning and noteable images from the contest were selected from over a thousand entries from 55 countries around
planet Earth. Also featured in the contest
compilation video (vimeo), the moving images are a testament to the importance and beauty of our world at night.

Awesome image. And I liked the compilation video showing the runners-up and honorable mentions.
Very nice!

I notice that the link address for "RĂ©union Island" is
http://apod.nasa.gov/apod/astropix.html. This seems to me to be incorrect.

<<It is natural that the human species has been adapted to lowland environment where oxygen is generally abundant. When people from the general lowlands go to altitudes above 2,500 metres (8,200 ft), they experience mountain sickness, which is a type of hypoxia, a clinical syndrome of severe lack of oxygen. Complications include fatigue, dizziness, breathlessness, headaches, insomnia, malaise, nausea, vomiting, body pain, loss of appetite, ear-ringing, blistering and purpling and of the hands and feet, and dilated veins. The sickness is compounded by related symptoms such as cerebral oedema (swelling of brain) and pulmonary oedema (fluid accumulation in lungs). For several days, they breathe excessively and burn extra energy even when the body is relaxed. The heart rate then gradually decreases. Hypoxia, in fact, is one of the principal causes of death among mountaineers. In women, pregnancy can be severely affected, such as development of high blood pressure, called preeclampsia, which causes premature labour, low birth weight of babies, and often complicated with profuse bleeding, seizures, and death of the mother. There are distinctive characteristics of high-altitude environments, including low concentration of available oxygen (which is due to lower barometric pressure), increased solar radiation, greater daily temperature fluctuation, aridity, low biomass, and limitation on energy production. At elevations above 7,600 metres (24,900 ft), lack of oxygen becomes seriously lethal.>>

That should read
some people. The vast majority of people can go that high with nothing more than a tendency to get out of breath when they exercise. Typical aircraft cabin altitudes are 7000-8000 feet, and virtually nobody has problems. Most non-acclimated people don't experience significant mountain sickness symptoms until they are over 10,000 feet; 12,000 feet is more common. Even at 14,000 feet or more, serious problems remain rare.
20,000 feet, however, is a different matter.
