Segundo Deus, o espírito pode também jorrar do nosso corpo, afim de dar à luz na sombra estonteante de uma vela moribunda, algo pálida, contrariando todo o tesão de antes apertado e ardente...

Astronomy picture of the day - 2017 February 28 - A White Oval Cloud on Jupiter from Juno
Image Credit: NASA, JPL-Caltech, SwRI, MSSS; Processing: Roman Tkachenko
Explanation: This storm cloud on Jupiter is almost as large as the Earth. Known as a white oval, the swirling cloud is a high pressure system equivalent to an Earthly anticyclone. The cloud is one of a "string of pearls" ovals south of Jupiter's famous Great Red Spot. Possibly, the Great Red Spot is just a really large white oval than turned red. Surrounding clouds show interesting turbulence as they flow around and past the oval. The featured image was captured on February 2 as NASA's robotic spacecraft Juno made a new pass just above the cloud tops of the Jovian world. Over the next few years, Juno will continue to orbit and probe Jupiter, determine atmospheric water abundance, and attempt to determine if Jupiter has a solid surface beneath its thick clouds.

Astronomy picture of the day - 2017 February 27 - Four Quasar Images Surround a Galaxy Lens
Image Credit: ESA/Hubble, NASA, Sherry Suyu et al.
Explanation: An odd thing about the group of lights near the center is that four of them are the same distant quasar. This is because the foreground galaxy -- in the center of the quasar images and the featured image -- is acting like a choppy gravitational lens. A perhaps even odder thing is that by watching these background quasars flicker, you can estimate the expansion rate of the universe. That is because the flicker timing increases as the expansion rate increases. But to some astronomers, the oddest thing of all is that these multiply imaged quasars indicate a universe that is expanding a bit faster than has been estimated by different methods that apply to the early universe. And that is because ... well, no one is sure why. Reasons might include an unexpected distribution of dark matter, some unexpected effect of gravity, or something completely different. Perhaps future observations and analyses of this and similarly lensed quasar images will remove these oddities.

Astronomy picture of the day - 2017 February 26 - A Supercell Thunderstorm Cloud Over Montana

Explanation: Is that a spaceship or a cloud? Although it may seem like an alien mothership, it's actually a impressive thunderstorm cloud called a supercell. Such colossal storm systems center on mesocyclones -- rotating updrafts that can span several kilometers and deliver torrential rain and high winds including tornadoes. Jagged sculptured clouds adorn the supercell's edge, while wind swept dust and rain dominate the center. A tree waits patiently in the foreground. The above supercell cloud was photographed in 2010 July west of Glasgow, Montana, USA, caused minor damage, and lasted several hours before moving on.

Astronomy picture of the day - 2017 February 25 - All Planets Panorama
Image Credit & Copyright: Tunç Tezel (TWAN)
Explanation: For 360 degrees, a view along the plane of the ecliptic is captured in this remarkable panorama, with seven planets in a starry sky. The mosaic was constructed using images taken during January 24-26, from Nacpan Beach, El Nido in Palawan, Philippines. It covers the eastern horizon (left) in dark early morning hours and the western horizon in evening skies. While the ecliptic runs along the middle traced by a faint band of zodiacal light, the Milky Way also cuts at angles through the frame. Clouds and the Moon join fleeting planet Mercury in the east. Yellowish Saturn, bright star Antares, and Jupiter lie near the ecliptic farther right. Hugging the ecliptic near center are Leo's alpha star Regulus and star cluster M44. The evening planets gathered along the ecliptic above the western horizon, are faint Uranus, ruddy Mars, brilliant Venus, and even fainter Neptune. A well labeled version of the panorama can be viewed by sliding your cursor over the picture, or just following this link.

Expressões populares portuguesas - Do tempo da Maria Cachucha
Significado:
Muito antigo.
Origem:
A cachucha era uma dança espanhola a três tempos, em que o dançarino, ao som das castanholas,
começava a dança num movimento moderado, que ia acelerando, até terminar num vivo volteio.
Esta dança
teve uma certa voga em França, quando uma célebre dançarina, Fanny Elssler, a dançou na Ópera de Paris.
Em
Portugal, a popular cantiga Maria Cachucha (ao som da qual, no séc. XIX, era usual as pessoas do povo
dançarem) era uma adaptação da cachucha espanhola, com uma letra bastante gracejadora, zombeteira.
