Artigo - Oceanario de Lisboa - Melhor aquario do mundo

Ocenario de Lisboa



O site de viagens Trip Advisor reuniu avaliações deixadas por viajantes de todo o mundo e atribuiu o título de Melhor Aquário do Mundo ao Oceanário de Lisboa, que é o segundo maior da Península Ibérica.

Desde que foi inaugurado, em 1998, tem recebido cerca de um milhão de visitantes por ano, que lá vão ver várias espécies de peixes, anfíbios, aves, invertebrados, mamíferos, plantas e algas, distribuídos por quatro habitats marinhos diferentes, desde as águas temperadas, às tropicais e frias, recriados em vários espaços.

O aquário principal, com cinco milhões de litros de água salgada, simula o puro oceano e é a principal atração, com tubarões, peixes-lua e outras tantas espécies a nadar em liberdade.

Explanation: Orbiting above the lunar nearside on August 21, the Lunar Reconnaissance Orbiter turned to look back on a bright, Full Earth. As anticipated its Narrow Angle Camera scanned this sharp view of our fair planet, catching the shadow of the Moon racing along a path across the United States at about 1,500 miles per hour. In fact, the dark lunar shadow is centered over Hopkinsville, Kentucky at 1:25:30 Central Daylight Time. From there, the New Moon blocked the Sun high in clear skies for about 2 minutes and 40 seconds in a total solar eclipse.

Artigo - Cuba desenvolveu vacina contra o cancro




Todos nós sabemos que o câncer hoje infelizmente é um dos negócios mais rentáveis.

Muitas empresas, como laboratórios farmacêuticos, faturam bilhões com essa doença.

Mas nós acreditamos na ciência do bem.

Existem sim pesquisadores que dedicam a vida para encontrar a cura de doenças consideradas incuráveis.

Um exemplo disso é o grupo de médicos e microbiologistas cubanos, que, com um orçamento muito limitado, conseguiu desenvolver a primeira vacina mundial contra o câncer de pulmão - a CIMAvax EGF.

Essa vacina já foi usada em mais de 4 mil pessoas que sofrem com a doença.

O resultado é incrível!

Ela é capaz de prolongar e melhorar o tempo de vida dos pacientes, mesmo quando o câncer já está bem avançado.

Foram necessários 16 anos de pesquisa para se chegar à fórmula da vacina.

O melhor é que ela não causa efeitos colaterais graves.

O mais interessante é que um país pobre e subdesenvolvido como Cuba conseguiu alcançar uma expressiva vitória contra a maior doença dos tempos modernos, mas os gigantes farmacêuticos, com toda a sua força econômica, não chegaram nem perto de algo parecido.


A vacina funciona atacando uma proteína chamada "fator de crescimento epidérmico", ou EGF, que permite que células cancerígenas do pulmão cresçam.

A CIMAvax estimula o sistema imunológico a criar anticorpos que se ligam ao EGF, impedindo que esta proteína alimente as células cancerosas.

A vantagem é que ela poupa a pessoa de se submeter às altas doses de quimioterapia, garantindo mais tempo de vida e com mais qualidade.

Com a administração dessa vacina, o paciente sofre menos falta de ar e, às vezes, esse sintoma até desaparece definitivamente.

Da mesma forma, ocorre com a dor.

Além disso, a pessoa volta a ganhar peso, melhora o apetite e passa a ter mais energia no dia a dia.

A vacina já está chegando em outros países, como na Bósnia, Herzegovina, Colômbia, Paraguai e Peru.

Saturn in Blue and Gold 
Image Credit: Cassini Imaging TeamSSIJPLESANASA
Explanation: Why is Saturn partly blue? The featured picture of Saturn approximates what a human would see if hovering close to the giant ringed world. The image was taken in 2006 March by the robot Cassini spacecraft now orbiting Saturn. Here Saturn's majestic rings appear directly only as a thin vertical line. The rings show their complex structure in the dark shadows they create on the image left. Saturn's fountain moon Enceladus, only about 500 kilometers across, is seen as the bump in the plane of the rings. The northern hemisphere of Saturn can appear partly blue for the same reason that Earth's skies can appear blue -- molecules in the cloudless portions of both planet's atmospheres are better at scattering blue light than red. When looking deep into Saturn's clouds, however, the natural gold hue of Saturn's clouds becomes dominant. It is not known why southern Saturn does not show the same blue hue -- one hypothesis holds that clouds are higher there. It is also not known why Saturn's clouds are colored gold. Next month, Cassini will end its mission with a final dramatic dive into Saturn's atmosphere.

Artigo - Futebol, Corruptos e Cia. Ilimitada

Raramente aqui falo de futebol e mesmo dos triunfos do Benfica, tantos eles são que dava para enjoar os adversarios...Mas é que o Sporting, o seu "presidente" Bruno Carvalho e o fantastico JJ, não conseguindo protagonismo positivo no relvado lanção-se em poléticas palermices em que são mestres de obra...
Mas que culpa têm muitos dos excelentes atletas do Sporting que lhes tenha sido atribuido semelhantes e dirigentes parolos !
Mais um queixumezinho : querem agora, que Eliseu seja castigado pela "entrada" sobre Diogo Viana, no Benfica-Belenenses do passado sábado, que gerou «alarme social ! ».
E no entretanto o Sporting vai alegando, protestando, denunciando, como se o mundo além dele não existisse. Coitadinhos : até parece que o mundo inteiro conhece e està contra o Sporting (de Lisbonne) como é conhecido.
O Sporting espera agora uma análise rápida da Comissão de Instrutores, na expectativa de uma decisão em processo sumário, tendo em conta que há reunião do Conselho de Disciplina nesta terça.feira. (bla, bla, bla, bla,... faz vender jornais e até o "Correio da Manhã"

A Total Solar Eclipse over Wyoming

Explanation: Will the sky be clear enough to see the eclipse? This question was on the minds of many people attempting to view yesterday's solar eclipse. The path of total darkness crossed the mainland of the USA from coast to coast, from Oregon to South Carolina -- but a partial eclipse occurred above all of North America. Unfortunately, many locations saw predominantly clouds. One location that did not was a bank of Green River Lake, Wyoming. There, clouds blocked the Sun intermittantly up to one minute before totality. Parting clouds then moved far enough away to allow the center image of the featured composite sequence to be taken. This image shows the corona of the Sun extending out past the central dark Moon that blocks our familiar Sun. The surrounding images show the partial phases of the solar eclipse both before and after totality.

Astronomy picture of the day - 2017 August 20 - Time-Lapse: A Total Solar Eclipse

Time-Lapse: A Total Solar Eclipse 
Video Credit & Copyright: Colin Legg
Explanation: Have you ever experienced a total eclipse of the Sun? This time-lapse movie depicts such an eclipse in dramatic detail, seen from Australia in 2012. As the video begins, a slight dimming of the Sun and the surrounding Earth is barely perceptible. As the Moon moves to cover nearly the entire Sun, darkness sweeps in from the left -- the fully blocked part of the Sun. At totality, only the bright solar corona extends past the edges of the Moon, and darkness surrounds you. Distant horizons are still bright, though, as they are not in the darkest part of the shadow. At mid-totality the darkness dips to the horizon below the eclipsed Sun, created by the shadow cone -- a corridor of shadow that traces back to the Moon. As the total solar eclipse ends -- usually after a few minutes -- the process reverses and Moon's shadow moves off to the other side. Tomorrow afternoon's total solar eclipse -- visible as at least a partial eclipse over all of North America -- can be experienced at social gatherings, some of which are being organized by local libraries.

Explanation: This mountain and night skyscape stretches across the French Pyrenees National Park on August 12, near the peak of the annual Perseid meteor shower. The multi-exposure panoramic view was composed from the Col d'Aubisque, a mountain pass, about an hour before the bright gibbous moon rose. Centered is a misty valley and lights from the region's Gourette ski station toward the south. Taken over the following hour, frames capturing some of the night's long bright perseid meteors were aligned against the backdrop of stars and Milky Way.

Data - Hubble Legacy ArchiveEuropean Southern Observatory
Explanation: Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy's two spiral arms extending from a pronounced central bar have a hook-like appearance in wide-field images. But this mosaicked close-up, constructed from Hubble Space Telescope and European Southern Observatory data, follows the galaxy's structure in amazing detail. Obscuring dust lanes, young blue star clusters and reddish star forming regions surround a core of yellowish light from an older population of stars. The sharp image data also reveal more distant background galaxies seen right through NGC 2442's star clusters and nebulae. The image spans about 75,000 light-years at the estimated distance of NGC 2442.

Texto - Os pirolitos do Mestre Gaudêncio

Ai esta o Senhor Gaudencio! ‘bora amigos qu’hoje vai ser igual a todas as quartas-feiras. Gaudêncio oferecia  sempre alguns pirolitos para a malta (e aquele berlinde apetitoso…)

Era uma alegria intensa ;  o mais importante, além da gasosa, eram os brindes na parte escondida de trás da rolha que revelava, de quando em vez, (mas muito raramente uma gasosa, outro pirolito ou então, prémio supremo, um “Canada Dry”).

Pouco importa, éramos tão felizes naqueles tempos. Tudo servia pr’a brincadeira. Era na Escola de Regentes Agrícolas, era o padrinho Chico Boazinha, era a madrinha bondososa, eram as corridas com arco até à “Mitra 2” e os regressos ansiosos por uma gota de agua…

Se o céu existe (ai tenho algumas duvidas), vamos passar tempos memoriais até que… passemos para outra vida. De qualquer forma ficaremos sempre a ganhar.

Astronomy picture of the day - 2017 August 14 - Charon Flyover from New Horizons


Charon Flyover from New Horizons 
Video Credit: NASAJHUAPLSwRI, P. Schenk & J. Blackwell (LPI); Music: Juicy by ALBIS
Explanation: What if you could fly over Pluto's moon Charon -- what might you see? The New Horizons spacecraft did just this in 2015 July as it zipped past Pluto and Charon with cameras blazing. The images recorded allowed for a digital reconstruction of much of Charon's surface, further enabling the creation of fictitious flights over Charon created from this data. One such fanciful, minute-long, time-lapse video is shown here with vertical heights and colors of surface features digitally enhanced. Your journey begins over a wide chasm that divides different types of Charon's landscapes, a chasm that might have formed when Charon froze through. You soon turn north and fly over a colorful depression dubbed Mordor that, one hypothesis holds, is an unusual remnant from an ancient impact. Your voyage continues over an alien landscape rich with never-before-seen craters, mountains, and crevices. The robotic New Horizons spacecraft has now been targeted at Kuiper Belt object 2014 MU 69, which it should zoom past on New Year's Day 2019.

Explanation: Only in the fleeting darkness of a total solar eclipse is the light of the solar corona easily visible. Normally overwhelmed by the bright solar disk, the expansive corona, the sun's outer atmosphere, is an alluring sight. But the subtle details and extreme ranges in the corona's brightness, although discernible to the eye, are notoriously difficult to photograph. Pictured here, however, using multiple images and digital processing, is a detailed image of the Sun's corona taken during the 2008 August total solar eclipse from Mongolia. Clearly visible are intricate layers and glowing caustics of an ever changing mixture of hot gas and magnetic fields. Bright looping prominences appear pink just above the Sun's limb. A similar solar corona might be visible through clear skies in a thin swath across the USA during a total solar eclipse that occurs just one week from tomorrow.

Explanation: A darkened sky holds bright planet Venus, the New Moon in silhouette, and the shimmering corona of the Sun in this image of a total solar eclipse. A composite of simultaneous telephoto and wide angle frames it was taken in the path of totality 18 years ago, August 11, 1999, near Kastamonu, Turkey. That particular solar eclipse is a member of Saros 145. Known historically from observations of the Moon's orbit, the Saros cycle predicts when the Sun, Earth, and Moon will return to the same geometry for a solar (or lunar) eclipse. The Saros has a period of 18 years, 11 and 1/3 days. Eclipses separated by one Saros period belong to the same numbered Saros series and are very similar. But the path of totality for consecutive solar eclipses in the same Saros shifts across the Earth because the planet rotates for an additional 8 hours during the cycle's fractional day. So the next solar eclipse of Saros 145 will also be a total eclipse, and the narrow path of totality will track coast to coast across the United States on August 21, 2017.

Explanation: This weekend, meteors will rain down near the peak of the annual Perseid Meteor Shower. Normally bright and colorful, the Perseid shower meteors are produced by dust swept up by planet Earth from the orbit of Comet Swift-Tuttle. They streak from a radiant in Perseus, above the horizon in clear predawn skies. Despite interfering light from August's waning gibbous moon, this year's Perseids will still be enjoyable, especially if you can find yourself in an open space, away from city lights, and in good company. Frames used in this composite view capture bright Perseid meteors from the 2016 meteor shower set against a starry background along the Milky Way, with even the faint Andromeda Galaxy just above center. In the foreground, astronomers of all ages have gathered on a hill above the Slovakian village of Vrchtepla.

Explanation: August's Full Moon is framed in this sharp, high dynamic range composition. Captured before sunrise on August 8 from Sydney, Australia, south is up and the Earth's dark, umbral shadow is at the left, near the maximum phase of a partial lunar eclipse. Kicking off the eclipse season, this time the Full Moon's grazing slide through Earth's shadow was visible from the eastern hemisphere. Up next is the much anticipated total solar eclipse of August 21. Then, the New Moon's shadow track will include North America, the narrow path of totality running coast to coast through the United States.

Spiral Galaxy NGC 1512: The Inner Ring 
Image Credit: NASAESAHubble Space Telescope
Explanation: Most galaxies don't have any rings -- why does this galaxy have two? To begin, the bright band near NGC 1512's center is a nuclear ring, a ring that surrounds the galaxy center and glows brightly with recently formed stars. Most stars and accompanying gas and dust, however, orbit the galactic center in a ring much further out -- here seen near the image edge. This ring is called, counter-intuitively, the inner ring. If you look closely, you will see this the inner ring connects ends of a diffuse central bar that runs horizontally across the galaxy. These ring structures are thought to be caused by NGC 1512's own asymmetries in a drawn-out process called secular evolution. Thegravity of these galaxy asymmetries, including the bar of stars, cause gas and dust to fall from the inner ring to the nuclear ring, enhancing this ring's rate of star formation. Some spiral galaxies also have a third ring -- an outer ring thatcircles the galaxy even further out.

Explanation: On July 11, the Juno spacecraft once again swung near the turbulent Jovian cloud tops. On its seventh orbital closest approach this perijove passage brought Juno within 3,500 kilometers of the Solar System's largest planetary atmosphere. Near perijove the rotating JunoCam was able to record this stunning, clear view of one of Jupiter's signature vortices. About 8,000 kilometers in diameter, the anticyclonic storm system was spotted in Jupiter'sNorth North Temperate Zone in the 1990s. That makes it about half the size of an older and better known Jovian anticyclone, the Great Red Spot, but only a little smaller than planet Earth. At times taking on reddish hues, the enormous storm system is fondly known as a North North Temperate Zone Little Red Spot.

Pelican Nebula Close-up 
Image Credit & Copyright: Sara Wager
Explanation: The prominent ridge of emission featured in this vivid skyscape is designated IC 5067. Part of a larger emission region with a distinctive shape, popularly called The Pelican Nebula, the ridge spans about 10 light-years and follows the curve of the cosmic pelican's head and neck. Fantastic, dark shapes inhabiting the view are clouds of cool gas and dust sculpted by energetic radiation from young, hot, massive stars. But stars are also forming within the dark shapes. Twin jets emerging from the tip of the long, dark tendril left of center are the telltale signs of an embedded protostar cataloged as Herbig-Haro 555 (HH 555). In fact, other Herbig-Haro objects indicating the presence of protostars are found within the frame. The Pelican Nebula itself, also known as IC 5070, is about 2,000 light-years away. To find it, look northeast of bright star Deneb in the high flying constellation Cygnus.

Explanation: Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only realmonster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the featured imageJets and winds of particles emitted from this star are also pushing away ambient gas and dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moons.

Perseid Meteors over Turkey

Explanation: The Perseid Meteor Shower, usually the best meteor shower of the year, will peak late next week. A person watching a clear sky from a dark location might see a bright meteor every minute. These meteors are actually specks of rock that have broken off Comet Swift-Tuttle and continued to orbit the Sun until they vaporize in Earth's atmosphere. The featured composite image shows a outburst of Perseids as they appeared over Turkey during last year's meteor shower. Enough meteors were captured to trace the shower's radiant back to the constellation of Perseus on the far left. The tail-end of the Perseids will still be going during the total solar eclipse on August 21, creating a rare opportunity for some lucky astrophotographers to image a Perseid meteor during the day.
