Astronomy picture of the day - 30-12-2014 - Observatory, Mountains, Universe
Image Credit & Copyright: Boris Dmitriev (Night Scape)
Explanation: The awesomeness in this image comes in layers. The closest layer, in the foreground, contains the Peak Terskol Observatory located in the northern Caucasus Mountains of Russia. The white dome over the 2-meter telescope is clearly visible. The observatory is located on a shoulder of Mt. Elbrus, the highest mountain in Europe, with other peaks visible in a nearby background layer. Clouds are visible both in front of and behind the mountain peaks. The featured three-image composite panorama was taken in 2014 August. Far in the distance is the most distant layer: the stars and nebulas of the night sky, with the central band of the Milky Way rising on the image right.

Astronomy picture of the day 2014-12-25 - This Comet Lovejoy
Image Credit & Copyright: Damian Peach
Explanation: Comet Lovejoy, C/2014 Q2, is framed like a cosmic Christmas tree with starry decorations in this colorful telescopic portrait, snapped on December 16th. Its lovely coma is tinted green by diatomic C2 gas fluorescing in sunlight. Discovered in August of this year, this Comet Lovejoy is currently sweeping north through the constellation Columba, heading for Lepus south of Orion and bright enough to offer good binocular views. Not its first time through the inner Solar System, this Comet Lovejoy will pass closest to planet Earth on January 7, while its perihelion (closest point to the Sun) will be on January 30. Of course, planet Earth's own 2015 perihelion passage is scheduled for January 4. A long period comet, this Comet Lovejoy should return again ... in about 8,000 years.

El pueblo pesquero de Nazaré, a 120 kilómetros al norte de Lisboa, ha sido escenario en los últimos años de hasta tres récords consecutivos de la ola más grande nunca surfeada. Esta semana, la costa portuguesa ha vuelto a recibir una fuerte marejada, pero de momento no se ha logrado batir la ola de 30 metros que el estadounidense Garret McNamara recorrió el en enero de 2013. En la imagen, un surfista no identificado se las apaña para bajar uno de estos gigantes de agua y espuma.
Astronomy picture of the day - 24-12-2014 - IC 1795: The Fishhead Nebula
Image Credit & Copyright: Bill Snyder (Bill Snyder Photography)
Explanation: To some, this nebula looks like the head of a fish. However, this colorful cosmic portrait really features glowing gas and obscuring dust clouds in IC 1795, a star forming region in the northern constellation Cassiopeia. The nebula's colors were created by adopting the Hubble false-color palette for mapping narrow emission from oxygen, hydrogen, and sulfur atoms to blue, green and red colors, and further blending the data with images of the region recorded through broadband filters. Not far on the sky from the famous Double Star Cluster in Perseus, IC 1795 is itself located next to IC 1805, the Heart Nebula, as part of a complex of star forming regions that lie at the edge of a large molecular cloud. Located just over 6,000 light-years away, the larger star forming complex sprawls along the Perseus spiral arm of our Milky Way Galaxy. At that distance, this picture would span about 70 light-years across IC 1795.

Morreu Joe Cocker - "Don't let me be misunderstood" - Video - Music
"Don't let me be misunderstood"
Joe Cocker morreu esta segunda-feira aos 70 anos. O cantor, mais conhecido pela cover dos Beatles With A Little Help From My Friends, morreu vítima de cancro do pulmão. Cocker teve uma carreira de mais de 40 anos, com sucessos como You Are So Beautiful, Up Where We Belong, You Can Leave Your Hat On ou Unchain My Heart. Joe Cocker: 'With a Little Help From My Friends' O agente do cantor, Barrie Marshall, avançou a notícia da morte do músico à BBC. Barrie Marshall disse que Joe Cocker "era simplesmente único". "Será impossível preencher o espaço que deixa nos nossos corações ", afirmou o agente. A Sony Music confirmou também a morte do músico em comunicado e avançou a causa do óbito: "John Robert Cocker, mais conhecido pela família, amigos e comunidade de fãs como Joe Cocker, morreu no dia 22 de dezembro de 2014, depois de uma dura batalha contra o cancro do pulmão." As melhores fotos de Joe Cocker Joe Cocker nasceu no dia 20 de maio de 1944 em Sheffield, em Inglaterra, onde viveu até aos 20 anos. Em 2007, foi agraciado pela rainha de Inglaterra. Reações à morte de Cocker Entre os artistas que prestaram tributo a Joe Cocker, está o baterista Ringo Starr, que escreveu no Twitter: "Adeus e que Deus te abençoe Joe Cocker." Para além do ex-Beatle, muitos outros prestaram a sua homenagem: Ronan Keating (cantor) publicou também no Twitter: "Estou muito triste por saber da morte de Joe Cocker. Que voz mais brilhante e única. Paz." Barrie Marshall, agente de Joe Cocker, referiu em comunicado: "É com muito pesar que soube do falecimento do nosso Joe Cocker. Ele foi, sem dúvida, a maior voz de rock/soul a sair da Grã-Bretanha – e continuou o mesmo homem ao longo de toda a vida." O vocalista dos Aerosmith, Steven Tyler, é outro dos famosos a prestar homenagem a Cocker. No Twitter escreveu: "Amamos-te para sempre, vamos sentir sempre a tua falta… Descansa em paz Joe Cocker." Já Bryan Adams escreveu: "Morreu Joe Cocker. Descansa em paz meu bom amigo, foste um dos melhores cantores de rock de sempre." Edgar Berger, pesidente executivo da Sony Internacaional, responsável pelo contrato inicial de Cocker, fez questão de prestar também um pequeno tributo: "Joe Cocker é um artista lendário da história do rock e do blues e, no entanto, era um dos homens mais humildes que já conheci."

Astronomy picture of the day - 23-12-2014 - The Cliffs of Comet Churyumov–Gerasimenko
Image Credit & Licence (CC BY-SA 3.0 IGO): ESA, Rosetta spacecraft, NAVCAM; Additional Processing: Stuart Atkinson
Explanation: These high cliffs occur on the surface of a comet. They were discovered to be part of the dark nucleus of Comet Churyumov–Gerasimenko (CG) by Rosetta, a robotic spacecraft launched by ESA which began orbiting the comet in early August. The ragged cliffs, as featured here, were imaged by Rosetta about two weeks ago. Although towering about one kilometer high, the low surface gravity of Comet CG would likely make a jump from the cliffs, by a human, survivable. At the foot of the cliffs is relatively smooth terrain dotted with boulders as large as 20 meters across. Data from Rosetta indicates that the ice in Comet CG has a significantly different deuterium fraction -- and hence likely a different origin -- than the water in Earth's oceans. The Rosetta spacecraft is scheduled to continue to accompany the comet as it makes its closest approach to the Sun in 2015 August.

Astronomy picture of the day - 22-12-2014 - The Mysterious Methane of Mars
Illustration Credit: Methane Workshop, Frascati Italy, Villanueva et al. 2009, NASA
Explanation: What's creating methane on Mars? Recent measurements from the robotic Curiosity rover currently rolling across Mars indicate a surprising 10-fold increase in atmospheric methane between measurements only months apart. Life is a major producer of methane on Earth, and so speculation is rampant that some sort of life -- possibly microbial life -- is creating methane beneath the surface of Mars. Other possibilities do exist, though, with a leading model being the sudden release of methane produced by the mixing of specific soil chemicals with underground water. Proposed origins of Martian methane are depicted in the featured illustration. The origin of Mars' methane is a very active area of research, with missions like Curiosity and India's Mars Orbiter Mission searching for clues by measuring methane abundance changes and possible byproducts of different methane-producing processes.
