Astronomy picture of the day - 2016 May 12 - A Transit of Mercury
Image Credit & Copyright: Howard Brown-Greaves
Explanation: On May 9, the diminutive disk of Mercury spent about seven and a half hours crossing in front of the Sun as viewed from the general vicinity of Earth. It was the second of 14 transits of the Solar System's innermost planet in the 21st century. Captured from Fulham, London, England, planet Earth the tiny silhouette shares the enormous solar disk with prominences, filaments, and active regions in this sharp image. But Mercury's round disk (left of center) appears to be the only dark spot, despite the planet-sized sunspots scattered across the Sun. Made with an H-alpha filter that narrowly transmits the red light from hydrogen atoms, the image emphasizes the chromosphere, stretching above the photosphere or normally visible solar surface. In H-alpha pictures of the chromosphere, normally dark sunspot regions are dominated by bright splotches called plages.

Roberto Carlos - "Olhando estrelas" - Musica
"Olhando estrelas"
Esta noite, debruçando-me à janela do meu quarto, com um céu de uma pureza limpida, as estrelas cintilantes envolvendo um quarto de crescente lua, vi como nunca antes tinha visto, um astro magnifico de luminosidade intensa, tentando dissimular o teu sorriso malicioso... Não te escondas "Pierre" (Pedro Teixeira), sei que és tu!
Astronomy picture of the day - 2016 May 11 - A Mercury Transit Music Video from SDO

Explanation: What's that small black dot moving across the Sun? Mercury. Possibly the clearest view of Mercury crossing in front of the Sun earlier this week was from Earth orbit. The Solar Dynamics Observatory obtained an uninterrupted vista recording it not only in optical light but also in bands of ultraviolet light. Featured here is a composite movie of the crossing set to music. Although the event might prove successful scientifically for better determining components of Mercury' ultra-thin atmosphere, the event surely proved successful culturally by involving people throughout the world in observing a rare astronomical phenomenon. Many spectacular images of this Mercury transit from around (and above) the globe are being proudly displayed.

Simulação excepcional - Veja o Titanic a afundar em tempo real - Video
Tem duas horas e quarenta minutos para preencher? Então pode assistir ao naufrágio do Titanic... em tempo real. Sim, é possível acompanhar ao minuto o que aconteceu após o trágico embate do famoso barco com um icebergue, através de uma simulação que tenta representar todos os momentos do acidente. E, ao contrário do que acontece na versão cinematográfica do evento, tudo se processou de forma bem mais lenta... No primeiro minuto, vemos o fatídico embate e, nos longos minutos que se seguem, a simulação dá-nos um olhar privilegiado do interior e exterior do barco enquanto este vai (lentamente) afundando. O resto é história.

Astronomy picture of the day - 2016 May 10 - Saturn and Mars visit Milky Way Star Clouds
Image Credit & Copyright: Carlos Eduardo Fairbairn ; Rollover Annotation: Judy Schmidt
Explanation: Planets, stars, nebulas and a galaxy -- this impressive image has them all. Closest to home are the two planets Mars (right) and Saturn (center), visible as the two bright orange spots in the upper half of the featured image. On the central right are the colorful Rho Ophiuchus star clouds featuring the bright orange star Antares lined up below Mars. These interstellar clouds contain both red emission nebulas and blue reflection nebulas. At the top right of the image is the Blue Horsehead reflection nebula. On the lower left are many dark absorption nebulas that extend from the central band of our Milky Way Galaxy. The featured deep composite was composed of multiple deep exposures taken last month from Brazil. Although you need a telescope to see the nebulosities, Saturn and Mars will remain visible to the unaided eye this month toward the east, just after sunset.
