Astronomy picture of the day - 2015 September 16 - Pluto from above Cthulhu Regio
Image Credit: NASA, Johns Hopkins Univ./APL, Southwest Research Inst.
Explanation: New high resolution images of Pluto are starting to arrive from the outer Solar System. The robotic New Horizons spacecraft, which zoomed by Pluto in July, has finished sending back some needed engineering data and is now transmitting selections from its tremendous storehouse of images of Pluto and its moons. The featured image, a digital composite, details a surprising terrain filled with craters, plains, landscape of unknown character, and landforms that resemble something on Earth but are quite unexpected on Pluto. The light area sprawling across the upper right has been dubbed Sputnik Planum and is being studied for its unusual smoothness, while the dark cratered area just under the spacecraft is known as Cthulhu Regio. So far, New Horizons has only shared a few percent of the images and data it took during its Pluto flyby, but will continue to send back new views of the dwarf planet even as it glides outward toward even more distant explorations.

Astronomy picture of the day - 2015 September 15 - A Spiral Aurora over Iceland
Image Credit & Copyright: Davide Necchi
Explanation: What's happened to the sky? Aurora! Captured late last month, this aurora was noted by Icelanders for its great brightness and quick development. The aurora resulted from a solar storm, with high energy particles bursting out from the Sun and through a crack in Earth's protective magnetosphere a few days later. Although a spiral pattern can be discerned, creative humans might imagine the complex glow as an atmospheric apparition of any number of common icons. In the foreground of the featured image is the Ölfusá River, while the lights illuminate a bridge in Selfoss City. Just beyond the low clouds is a nearly full Moon. The liveliness of the Sun -- and the resulting auroras on Earth -- is slowly diminishing as the Sun emerges from a Solar maximum of surface activity and evolves towards a historically more quite period in its 11-year cycle. In fact, solar astronomers are waiting to see if the coming Solar minimum will be as unusually quiet as the last one, where sometimes months would go by with no discernible sunspots or other active solar phenomena.

Astronomy picture of the day - 2015 September 13 - A Partial Solar Eclipse over Texas
Image Credit & Copyright: Jimmy Westlake (Colorado Mountain College) & Linda Westlake
Explanation: It was a typical Texas sunset except that most of the Sun was missing. The location of the missing piece of the Sun was not a mystery -- it was behind the Moon. Featured here is one of the more interesting images taken of a partial solar eclipse that occurred in 2012, capturing a temporarily crescent Sun setting in a reddened sky behind brush and a windmill. The image was taken about 20 miles west of Sundown, Texas, USA, just after the ring of fireeffect was broken by the Moon moving away from the center of the Sun. Today a new partial solar eclipse of the Sun will be visible from Earth. Unfortunately for people who live in Texas, today's eclipse can only be seen from southern Africa and Antarctica.

Astronomy picture of the day - 2015 September 11 - A Giant Squid in the Flying Bat
Image Credit & Copyright: Steve Cannistra (StarryWonders)
Explanation: Very faint but also very large on planet Earth's sky, a giant Squid Nebula cataloged as Ou4, and Sh2-129 also known as the Flying Bat Nebula, are both caught in this scene toward the royal constellation Cepheus.Composed with a total of 20 hours of broadband and narrowband data, the telescopic field of view is almost 4 degrees or 8 Full Moons across. Discovered in 2011 by French astro-imager Nicolas Outters, the Squid Nebula's alluringbipolar shape is distinguished here by the telltale blue-green emission from doubly ionized oxygen atoms. Though apparently completely surrounded by the reddish hydrogen emission region Sh2-129, the true distance and nature of the Squid Nebula have been difficult to determine. Still, a recent investigation suggests Ou4 really does lie within Sh2-129 some 2,300 light-years away. Consistent with that scenario, Ou4 would represent a spectacular outflow driven by atriple system of hot, massive stars, cataloged as HR8119, seen near the center of the nebula. If so, the truly giant Squid Nebula would physically be nearly 50 light-years across.

Texto - "O Pifaro leiteiro" - Documento invulgar do nosso correspondente Peter Abrunheira do Riacho de fevereiro
Preciosidade alentejana. Beja, ano de 1771. Fenomenal! Isto é uma reliquia. Descrição peculiar, num português precioso usado na época . O rapaz usou o pífaro leiteiro ( já tinha ouvido chamar-lhe muitos nomes, este é mais um ) no vaso da rapariga. (so faltava referir as partes fodengas!)
"Vistos os autos, se prova que , indo a autora para a fonte, lhe saiu ao encontro o réu, e, levantando-lhe o faldistério, lhe encaixou o pifaro leiteiro no vaso natural, e, esgaravatando, ficou consumada a desfloração. Portanto condeno o réu a que pague as custas e selos e receba a moça e o absolvo das garras da lei. Beja, 25 de novembro de 1771. O juiz (a) Doutor Manuel da Costa Silva Araujo"
