High Energy Andromeda

Explanation: A mere 2.5 million light-years away, the Andromeda Galaxy, also known as M31, really is just next door as large galaxies go. In this (inset) scan, image data from NASA's Nuclear Spectrosopic Telescope Array has yielded the best high-energy X-ray view yet of our large neighboring spiral, revealing some 40 extreme sources of X-rays, X-ray binary star systems that contain a black hole or neutron star orbiting a more normal stellar companion. In fact, larger Andromeda and our own Milky Way are the most massive members of the local galaxy group. Andromeda is close enough that NuSTAR can examine its population of X-ray binaries in detail, comparing them to our own.The background image of Andromeda was taken by NASA's Galaxy Evolution Explorer in energetic ultraviolet light.

Astronomy picture of the day - 2016 January 6 - Comets and Bright Star

Explanation: This timely, telescopic, two panel mosaic spans about 10 full moons across planet Earth's predawn skies. Recorded as the year began from Tenerife, Canary Islands, near the top of the frame are the faint coma and tail ofComet Borrelly (P/19). A comet with a seven year orbital period, Borrelly's nucleus was visited by the ion propelled spacecraft Deep Space 1 near the beginning of the 21st century. Anchoring the scene at the bottom is brilliant star Arcturus (Alpha Bootes) and Comet Catalina (C/2013 US10) a first time visitor from the Oort Cloud. Catalina's yellowish dust tail extends below and right. Buffeted by winds and storms from the Sun, the comet's complex ion tail sweeps up and toward the right, across most of the field of view. Remarkably, one of the composition's 30 second exposure subframes also caught the trail of a bright meteor, slashing toward the left between comets and bright star.

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

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.
