A rarity: Venus transit in front of the sun – Planeta Venus trece in fata soarelui
Romanian: Maiestria lui Dumnezeu in ordinea universului. Planeta Venus trece in fata soarelui doar de doua ori la fiecare suta de ani. Cu ochiul liber (protejat de echipament special) planeta se vede doar ca un disc negru cand trece prin fata soarelui. Au fost inregistrate doar 6 de “transits” (treceri prin fata soarelui) de cand s-a inventat telescopul in anii urmatori – 1631 si 1639, 1761 si 1769, 1874 si 1882, 2004 si 2012 (Iunie 5) (Notite din al doilea video) Primul video este filmat folosind “lungimi de unde ultraviolete extreme şi o parte a spectrului vizibil”.
English: What’s Up for June? It won’t happen again until December 2117. On June 5th, 2012, Venus will transit(pass in front of) the face of the sun in an event of both historical and observational importance. First video shows Venus’ transit and the second video explains it.
Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun’s atmosphere, magnetic field and also provide a better understanding of the role the sun plays in Earth’s atmospheric chemistry and climate. SDO provides images with resolution 8 times better than high-definition television and returns more than a terabyte of data each day.On June 5 2012, SDO collected images of the rarest predictable solar event–the transit of Venus across the face of the sun. This event lasted approximately 6 hours and happens in pairs eight years apart, which are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117.The videos and images displayed here are constructed from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. The red colored sun is the 304 angstrom ultraviolet, the golden colored sun is 171 angstrom, the magenta sun is 1700 angstrom, and the orange sun is filtered visible light. 304 and 171 show the atmosphere of the sun, which does not appear in the visible part of the spectrum.
