Astronomy picture of the day - 03-02-2015 - Jets from Comet Churyumov-Gerasimenko

Explanation: Where do comet tails come from? Although it is common knowledge that comet tails and comas originate from comet nuclei, exactly how that happens is an active topic of research. One of the best images yet of emerging jets is shown in the featured image, taken last November by the robotic Rosetta spacecraft in orbit around the Comet 67P/Churyumov-Gerasimenko (Comet CG), and released last month. The overexposed picture shows plumes of gas and dust escaping numerous places from the Comet CG's nucleus as it nears the Sun and heats up. Although Comet CG is currently further out from the Sun than Mars, its orbit will take it almost as close as the Earth this coming August, at which time its jet activity is expected to increase by a factor of about 100. You've likely seen some debris from comet nuclei before but in another form -- when sand-sized bits end their journey through the Solar System by impacting the atmosphere of Earth as meteors.

Astronomy picture of the day - 02-02-2015 - Titan Seas Reflect Sunlight
Image Credit: VIMS Team, U. Arizona, ESA, NASA
Explanation: Why would the surface of Titan light up with a blinding flash? The reason: a sunglint from liquid seas. Saturn's moon Titan has numerous smooth lakes of methane that, when the angle is right, reflect sunlight as if they were mirrors. Pictured here in false-color, the robotic Cassini spacecraft orbiting Saturn imaged the cloud-covered Titan last summer in different bands of cloud-piercing infrared light. This specular reflection was so bright it saturated one of Cassini's infrared cameras. Although the sunglint was annoying -- it was also useful. The reflecting regions confirm that northern Titan houses a wide and complex array of seas with a geometry that indicates periods of significant evaporation. During its numerous passes of our Solar System's most mysterious moon, Cassini has revealed Titan to be a world with active weather -- including times when it rains a liquefied version of natural gas.

Le Qatar achète tout!
Mondial de Handball-Qatar 2015. L’Emirat du Qatar organise actuellement le Mondial de Qatar, une compétition dans laquelle l’Equipe de France est favorite. Mais, outres les questions de nationalisation de joueurs étrangers afin de présenter une équipe compétitive, la communauté internationale se pose aussi la question de savoir d’où viennent les supporters.
Un championnat du monde de handball au Qatar. Si le Qatar n’avait pas autant investi dans le sport, la question ne se poserait même pas. Mais le petit Etat, propriétaire, entre autres, du club de football du Paris Saint Germain, ne pouvait pas montrer le désintérêt des habitants de son Emirat pour ce sport au monde entier. Des stades ont été construits, un investissement a été fait, et l’image du pays est en jeu.
Le Qatar, qui présente une sélection de joueurs lors de ce Mondial 2015, ne fait pas figure de favori dans la compétition, mais se doit de présenter une équipe compétitive. De ce fait, ils ont « nationalisé » des joueurs de différentes nationalités, qui n’étaient pas retenus avec leur sélection. Tout comme ils avaient tenté de le faire en football, en nationalisant notamment l’ancien attaquant du Werder Brême, le brésilien Ailton, en 2004, comme le révélait à l’époque l’Equipe.fr. Ainsi, deux Monténégrins, un Français, deux Bosniens, un Tunisien, un Cubain, un Espagnol, un Egyptien et sept Qataris compose l’équipe qui représente le Qatar pour ce Mondial.
Mais pour le Qatar, tout s’achète, même les supporters. C’est en partant de cet adage que l’Emirat a choisi de recruter,entre autres, 60 espagnols, afin de les faire venir au Qatar dans le but d’encourager la sélection qatari. Comme le révèle l’Express, ces derniers sont en grande partie des supporters des 3 clubs suivants : Ciudad Encantada, Puerto Sagunto et Villa de Aranda. Les « mercenaires » chantent à tue-tête tambours battants pour encourager les qatari, moyennant finances. Mais cela va même plus loin.
Afin que les stades paraissent remplis, le Qatar a payé les frais de déplacements de plus d’une vingtaine de fans de chaque nation représentée dans la compétition. L’un d’entre eux a témoigné sur la chaine d’informations BFM TV : le Qatar nous a payé l’avion au départ de Paris, l’hôtel… un palace cinq étoiles, avec le petit-déjeuner, le repas du midi, le repas du soir. On a le transfert à chaque match de l’équipe de France et les places bien sûr ».

Portugal: "Virar a pagina"
A deputada do Bloco de Esquerda Catarina Martins considerou hoje, no decorrer da "Marcha da Mudança" do Podemos, em Madrid, que a Europa está a viver "um virar de página" que também chegará a Portugal.
"Estamos a viver um virar de página na Europa. Nada ficará na mesma depois da Grécia, há pela primeira vez um governo eleito contra a austeridade. Mas para que haja mudança precisamos que essa luta contra a austeridade se estenda a outros países", considerou a deputada bloquista, no meio de uma multidão de várias dezenas de milhares de apoiantes do Podemos.
A "Marcha da Mudança", convocada pelo Podemos, encheu a Praça Cibeles, em Madrid, e um segmento da rua Alcala, rumo à Porta do Sol, passando em frente ao Banco de Espanha. "Espanha pode ser o próximo país a conseguir um governo contra a austeridade. Julgo que os países são diferentes - a realidade na Grécia é diferente da realidade de Espanha, Portugal e da Irlanda -, mas se há alguma esperança para a Europa, para o futuro, ela passa pelos países do Sul, que foram tão martirizados com memorandos da Troika", acrescentou Catarina Martins.
Para a deputada, estes países "têm populações que não foram derrotadas, que sabem fazer frente à finança, que dizem chega de alternância, chega do rotativismo, chega dos mesmos de sempre" a ser eleitos.
"A Grécia levantou-se, a Espanha está a levantar-se, Portugal também terá de fazer o seu caminho. São percursos diferentes. Mas em Portugal, quem tem hoje 18, 20, 30 anos olha para o seu país e diz 'Eu quero viver aqui' e sabe que tem de fazer parte deste movimento dos países dos Sul da Europa, contra a austeridade e o rotativismo", concluiu. Presente na marcha está igualmente a deputada Marisa Matias.

Astronomy picture of the day - 01-02-2015 - NGC 4676: When Mice Collide
Image Credit: ACS Science & Engineering Team, Hubble Space Telescope, NASA
Explanation: These two mighty galaxies are pulling each other apart. Known as the "Mice" because they have such long tails, each spiral galaxy has likely already passed through the other. The long tails are created by the relativedifference between gravitational pulls on the near and far parts of each galaxy. Because the distances are so large, the cosmic interaction takes place in slow motion -- over hundreds of millions of years. NGC 4676 lies about 300 million light-years away toward the constellation of Bernice's Hair (Coma Berenices) and are likely members of the Coma Cluster of Galaxies. The above picture was taken with the Hubble Space Telescope's Advanced Camera for Surveys in 2002. These galactic mice will probably collide again and again over the next billion years until they coalesce to form a single galaxy.
