Astronomy picture of the day - 15-01-2015 - Venus and Mercury at Sunset

Explanation: Inner planets Venus and Mercury can never wander far from the Sun in Earth's sky. This week you've probably seen them both gathered near the western horizon just after sunset, a close conjunction of bright celestial beacons in the fading twilight. The pair are framed in this early evening skyview captured on January 13 from the ruins of Szarvasko Castle in northwestern Hungary. Above the silhouette of the landscape's prominent volcanic hill Venus is much the brighter, separated from Mercury by little more than the width of two Full Moons. On Friday, planet Earth's early morning risers will also be treated to a close conjunction, when Saturn meets an old crescent Moon near the southeastern horizon at dawn.

Cuba, le charme de l'ancien
Le 17 décembre, Washington et La Havane annonçaient la reprise de relations bilatérales. De ses cinquante années d'isolement, Cuba sort avec un certain retard, mais aussi une certaine authenticité, argue le journaliste et écrivain William Ospina dans une tribune publiée par le quotidien colombien El Espectador.
Cuba, explique-t-il, "est le seul pays du continent à n'avoir pas détruit son magnifique patrimoine architectural. Ce qui, dans le reste de l'Amérique latine, a été démoli par une fièvre triviale de modernisation, Cuba l'a sauvé – parce qu'il n'avait pas les moyens matériels de le démolir, mais aussi parce que ces demeures [construites] pour un seul maître et cent esclaves se sont transformées en solution de logements pour les pauvres".
Ce retard, implore Ospina, doit devenir une force : "Le fait de n'avoir pas pâti des périodes les plus polluantes de l'industrie devrait permettre à Cuba d'entrer dans un processus industriel avec la prudence de la modernité".

Astronomy picture of the day - 13-01-2014 - The Soap Bubble Nebula
Explanation: Adrift in the rich star fields of the constellation Cygnus, this lovely, symmetric nebula was only recognized a few years ago and does not yet appear in some astronomical catalogs. In fact, amateur astronomer Dave Jurasevich identified it as a nebula on 2008 July 6 in his images of the complex Cygnus region that included the Crescent Nebula (NGC 6888). He subsequently notified the International Astronomical Union. Only eleven days later the same object was independently identified by Mel Helm at Sierra Remote Observatories, imaged by Keith Quattrocchi and Helm, and also submitted to the IAU as a potentially unknown nebula. The nebula, appearing on the left of thefeatured image, is now known as the Soap Bubble Nebula. What is the newly recognized nebula? Most probably it is a planetary nebula, a final phase in the life of a sun-like star.
