Astronomy picture of the day - 2015 August 9 - HCG 87: A Small Group of Galaxies
Image Credit: GMOS-S Commissioning Team, Gemini Observatory
Explanation: Sometimes galaxies form groups. For example, our own Milky Way Galaxy is part of the Local Group of Galaxies. Small, compact groups, like Hickson Compact Group 87 (HCG 87) shown above, are interesting partly because they slowly self-destruct. Indeed, the galaxies of HCG 87 are gravitationally stretching each other during their 100-million year orbits around a common center. The pulling creates colliding gas that causes bright bursts of star formation and feeds matter into their active galaxy centers. HCG 87 is composed of a large edge-on spiral galaxy visible near the image center, an elliptical galaxy visible to its right, and a spiral galaxy visible near the top. The small spiral near the center might be far in the distance. Several stars from our Galaxy are also visible in the foreground. Studying groups like HCG 87 allows insight into how all galaxies form and evolve.

O sua descaradona
Tire a roupa da janela
Que essa camisa sem dona
Lembra-me a dona sem ela
Dependurada com graça
Adejante, colorida
A sua roupa estendida
Afaga o rosto a quem passa
E pede que um pintor faça
Na sua estreita viela
Uma formosa aguarela
Dessa cena fadistona
O sua descaradona
Tire a roupa da janela
Que eu nao posso suportar
A visão que me sugere
Essa roupa de mulherVazia, posta a secar;
Pudera eu cinzelar
Do mundo a estatua mais bela
E inspirava-me naquela
Poupinha que me apaixona
Que essa camisa sem dona
Lembra-me a dona sem ela

25 miradouros em Lisboa - Largo da Academia das Belas Artes
Going down this square in Chiado you come across a terrace used as a parking lot, with a beautiful view over downtown Lisbon. A few steps further down, you get a closer look at the top of the Municipal Palace and of the triumphal arch of Rua Augusta.
Atravessando este largo no Chiado, depara-se com um terraço usado como parque de estacionamento, com uma bela vista da Baixa de Lisboa. Um pouco mais abaixo, é possível ver o topo dos Paços do Concelho e do arco triunfal da Rua Augusta.
Astronomy picture of the day - 2015 August 8 - Curiosity's View
Image Credit: Image Credit: NASA, JPL-Caltech, MSSS
Explanation: By planet Earth's calendar, the Curiosity Mars Rover reached its 3rd anniversary on the surface of the Red Planet on August 6. To celebrate, gaze across this dramatic panoramic view of diverse terrain typical of therover's journey to the layered slopes of Aeolis Mons, also known as Mount Sharp. Recorded with Curiosity's Mast Camera instrument, the scene looks south across gravel, sand ripples, and boulders toward rounded buttes. In the background, higher layers at left are toward the southeast, with southwest at panorama right. The individual images composing the view were taken on Curiosity's mission sols (martian days) 952 and 953 since the rover's landing on August 6, 2012.
