Astronomy picture of the day - 2017 August 22 - A Total Solar Eclipse over Wyoming
Image Credit & Copyright: Ben Cooper
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
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.

Astronomy picture of the day - 2017 August 18 - Perseids over the Pyrénées
Image Credit & Copyright: Jean-Francois Graffand
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.

Astronomy picture of the day - 2017 August 17 - NGC 2442: Galaxy in Volans
Image Credit & Copyright: Processing - Robert Gendler, Roberto Colombari
Data - Hubble Legacy Archive, European 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.
