Astronomy picture of the day - 2016 August 16 - Five Planets and the Moon over Australia
Image Credit & Copyright: Alex Cherney (Terrastro, TWAN)
Explanation: It is not a coincidence that planets line up. That's because all of the planets orbit the Sun in (nearly) a single sheet called the plane of the ecliptic. When viewed from inside that plane -- as Earth dwellers are likely to do -- the planets all appear confined to a single band. It is a coincidence, though, when several of the brightest planets all appear in nearly the same direction. Such a coincidence was captured just last week. Featured above, six planets and Earth's Moon were all imaged together last week, just before sunset, from Mornington Peninsula in Victoria, Australia. A second band is visible across the top of this tall image -- the central band of our Milky Way Galaxy.

Imagens do Mundo - Sitios lindos de Portugal - Sintra
Sintra é uma vila que mais parece saída de um conto de fadas. A sua paisagem verde é entrecortada aqui e ali por majestosos monumentos. O palácio de Sintra é um dos monumentos Portugueses mais conhecidos internacionalmente e estabelece-se por vezes comparação com o famoso palácio alemão Neuschwanstein, que inspirou os castelos da Walt Disney.
Astronomy picture of the day - 2016 August 15 - Human as Spaceship

Explanation: You are a spaceship soaring through the universe. So is your dog. We all carry with us trillions of microorganisms as we go through life. These multitudes of bacteria, fungi, and archaea have different DNA than you. Collectively called your microbiome, your shipmates outnumber your own cells. Your crew members form communities, help digest food, engage in battles against intruders, and sometimes commute on a liquid superhighway from one end of your body to the other. Much of what your microbiome does, however, remains unknown. You are the captain, but being nice to your crew may allow you to explore more of your local cosmos.

Astronomy picture of the day - 2016 August 14 - The Keyhole in the Carina Nebula
Image Credit: NASA, Hubble Heritage (AURA/STScI)
Explanation: The dark dusty Keyhole Nebula gets its name from its unusual shape. The looping Keyhole, in this featured classic image by the Hubble Space Telescope, is a smaller region inside the larger Carina Nebula. Dramatic dark dust knots and complex features are sculpted by the winds and radiation of the Carina Nebula's many massive and energetic stars. In particular, the shape of the dust cloud on the upper left of the Keyhole Nebula may stimulate the human imagination to appear similar to, for example, a superhero flying through a cloud, arm up, with a saved person in tow below. The region lies about 7,500 light-years away in planet Earth's southern sky. The Keyhole Nebula was created by the dying star Eta Carina , out of the frame, which is prone to violent outbursts during its final centuries.
