Artigo - “Todos falam da pequena nação marítima”: Portugal entre os países a visitar em 2018
A Lonely Planet, maior editora do mundo de guias de viagem coloca o nosso país como um destino que deve ser incluído na rota de qualquer viajante em 2018.
A Lonely Planet, editora de guia de viagens, é uma referência mundial para milhões de viajantes e a sua lista de tendências de viagem é seguida ‘religiosamente’ por quem adora viajar.
A viver um ‘boom’ sem precedentes na área do turismo, Portugal foi agora colocado numa restrita lista de dez países que devem ser visitados em 2018.
Na lista, o nosso país é destacado como “um centro dinâmico de arte, cultura e cozinha”, acessível em termos económicos e repleto de “maravilhas naturais”. Assim, e no entender da Lonely Planet, não é por acaso que “todos falam da pequena nação marítima”.

Astronomy picture of the day - 2017 October 24 - Haumea of the Outer Solar System
Illustration Credit: Instituto de Astrofísica de Andalucía
Explanation: One of the strangest objects in the outer Solar System has recently been found to have a ring. The object, named Haumea, is the fifth designated dwarf planet after Pluto, Ceres, Eris, and Makemake. Haumea's oblong shape makes it quite unusual. Along one direction, Haumea is significantly longer than Pluto, while in another direction Haumea has an extent very similar to Pluto, while in the third direction is much smaller. Haumea's orbit sometimes brings it closer to the Sun than Pluto, but usually Haumea is further away. Illustrated above, an artist visualizes Haumea as a cratered ellipsoid surrounded by a uniform ring. Originally discovered in 2003 and given the temporary designation of 2003 EL61, Haumea was renamed in 2008 by the IAU for a Hawaiian goddess. Besides the ring discovered this year, Haumea has two small moons discovered in 2005, named Hi'iaka and Namaka for daughters of the goddess.

Artigo - Outra vez (5) - Cristiano Ronaldo The best !
Cristiano Ronaldo é o melhor jogador do Mundo de 2017 para a FIFA.
O internacional português foi distinguido em Londres, na gala The Best.
O avançado do Real Madrid renova assim o título, que conquistou em 2016.
Cristiano Ronaldo vence pela quinta vez a distinção da FIFA, que durante vários anos foi em conjunto com a France Football, que atribui a Bola de Ouro.
Lionel Messi e Neymar Jr eram os outros nomeados.
O internacional português foi o melhor do mundo em 2017, 2016, 2014, 2013 e 2008. Refira-se que em 2008, ainda no Manchester United, o galardão era relativo a FIFA World Player of The Year.

Astronomy picture of the day - 2017 October 23 - NGC 4993: The Galactic Home of an Historic Explosion
Image Credit: NASA & ESA
Explanation: That reddish dot -- it wasn't there before. It's the dot to the upper left of galaxy NGC 4993's center, do you see it? When scanning the large field of possible locations of an optical counterpart to the unprecedentedgravitational wave event GW170817 in August, the appearance of this fading dot quickly became of historic importance. It pinpointed GW170817's exact location, thereby enabling humanity's major telescopes to examine the first everelectromagnetic wave counterpart to a gravitational wave event, an event giving strong evidence of being a short gamma-ray burst kilonova, the element-forming explosion that occurs after two neutron stars merge. The featured image oflenticular galaxy NGC 4993 by Hubble shows the fading dot several days after it was discovered. Analyses, continuing, include the physics of the explosion, what heavy elements formed, the similarity of the speeds of gravitational radiation and light, and calibrating a new method for determining the distance scale of our universe.

Astronomy picture of the day - 2017 October 22 - Two Black Holes Dancing in 3C 75

Explanation: What's happening at the center of active galaxy 3C 75? The two bright sources at the center of this composite x-ray (blue)/ radio (pink) image are co-orbiting supermassive black holes powering the giant radio source 3C 75. Surrounded by multimillion degree x-ray emitting gas, and blasting out jets of relativistic particles the supermassive black holes are separated by 25,000 light-years. At the cores of two merging galaxies in the Abell 400 galaxy cluster they are some 300 million light-years away. Astronomers conclude that these two supermassive black holes are bound together by gravity in a binary system in part because the jets' consistent swept back appearance is most likely due to their common motion as they speed through the hot cluster gas at 1200 kilometers per second. Such spectacular cosmic mergers are thought to be common in crowded galaxy cluster environments in the distant universe. In their final stages the mergers are expected to be intense sources of gravitational waves.
