Imagens do Mundo - Scotland says no!

"No nos dejéis así". Ese es el titular del día de la votación del tabloide británico 'Daily Mirror', acompañado de la bandera inglesa. Todo lo contrario a la portada del día siguiente, la de hoy, en la edición especial, con un gran no, con la Union Jack de fondo.

Poesia - Manuel Maria Barbosa du Bocage - "A vida"

"A vida"
A vida é filha da puta, A puta, é filha da vida ; nunca vi tanto filho da puta na puta da minha vida.

Explanation: For astrobiologists, these may be the four most tantalizing moons in our Solar System. Shown at the same scale, their exploration by interplanetary spacecraft has launched the idea that moons, not just planets, could have environments supporting life. The Galileo mission to Jupiter discoveredEuropa's global subsurface ocean of liquid water and indications ofGanymede'sinterior seas. At Saturn, the Cassini probe detected erupting fountains of water ice from Enceladus indicating warmer subsurface water on even that small moon, while finding surface lakes of frigid but still liquid hydrocarbons beneath the dense atmosphere of large moon Titan. Now looking beyond the Solar System,new research suggests that sizable exomoons, could actually outnumberexoplanets in stellarhabitable zones. That would make moons the most common type of habitable world in the Universe.
