Brasil - De três para duas dimensões: com pintura corporal, artista transforma modelos em quadros
A artista Alexa Meade, radicada em Los Angeles (Califórnia, EUA), decidiu reverter a tendência que dar tons 3D a pinturas em duas dimensões. Usando modelos como tela, ela transforma homens e mulheres em quadros com pintura corporal.
"Ao contrário de pinturas tradicionais que faz o truque de uma pintura em 2D parecer 3D, eu pego o mundo em 3D e crio a ilusão de que se trata de uma pintura 2D", explicou ao site "Night Flight" Alexa, que já expôs seus quadros vivos em Washington, Londres e Paris, entre outras cidades.

Brasil - Aeronáutica proíbe uso de drones em áreas públicas
RIO — De olho na segurança dos Jogos Olímpicos, o Departamento de Controle do Espaço Aéreo (Decea), da Aeronáutica, publicou, em dezembro, a regulamentação para o uso do espaço aéreo por aeronaves remotamente pilotadas, conhecidas como drones. Segundo a norma, a operação desses aparelhos sobre áreas povoadas e aglomerados de pessoas está, a princípio, proibida. Para utilizá-los, será necessário pedir autorização ao próprio Decea. Já o emprego de drones no interior de prédios e outras construções, total ou parcialmente fechadas, como ginásios e arenas, será de responsabilidade dos proprietários desses lugares, que deverão dar permissão para a atividade.

Astronomy picture of the day - 2016 January 5 - The Lagoon Nebula in Hydrogen, Sulfur, and Oxygen
Image Credit & Copyright: John Nemcik
Explanation: The majestic Lagoon Nebula is filled with hot gas and the home for many young stars. Spanning 100 light years across while lying only about 5000 light years distant, the Lagoon Nebula is so big and bright that it can beseen without a telescope toward the constellation of the Archer (Sagittarius). Many bright stars are visible from NGC 6530, an open cluster that formed in the nebula only several million years ago. The greater nebula, also known as M8and NGC 6523, is named "Lagoon" for the band of dust seen to the right of the open cluster's center. The featured image was taken in the light emitted by Hydrogen (shown in brown), Sulfur (red), and Oxygen (blue) and displayed inenhanced color. The featured picture is a newly processed panorama of M8, capturing twice the diameter of the Full Moon. Star formation continues in the Lagoon Nebula as witnessed by the many globules that exist there.

Astronomy picture of the day - 2016 January 4 - Earthset from the Lunar Reconnaissance Orbiter

Explanation: On the Moon, the Earth never rises -- or sets. If you were to sit on the surface of the Moon, you would see the Earth just hang in the sky. This is because the Moon always keeps the same side toward the Earth. Curiously, the featured image does picture the Earth setting over a lunar edge. This was possible because the image was taken from a spacecraft orbiting the Moon - specifically the Lunar Reconnaissance Orbiter (LRO). In fact, LRO orbits the Moon so fast that, from the spacecraft, the Earth appears to set anew about every two hours. The featured image captured one such Earthset about three months ago. By contrast, from the surface of the Earth, the Moon setsabout once a day -- with the primary cause being the rotation of the Earth. LRO was launched in 2009 and, while creating a detailed three dimensional map of the Moon's surface, is also surveying the Moon for water and possible good landing spots for future astronauts.

Astronomy picture of the day - 2016 January 3 - A Starry Night of Iceland
Explanation: On some nights, the sky is the best show in town. On this night, the sky was not only the best show in town, but a composite image of the sky won an international competition for landscape astrophotography. Thefeatured winning image was taken in 2011 over Jökulsárlón, the largest glacial lake in Iceland. The photographer combined six exposures to capture not only two green auroral rings, but their reflections off the serene lake. Visible in the distant background sky is the band of our Milky Way Galaxy and the Andromeda galaxy. A powerful coronal mass ejection from the Sun caused auroras to be seen as far south as Wisconsin, USA. Solar activity over the past week has resulted in auroras just over the past few days.
