Lynds Bright Nebula 159.

Over 150 light-years across, this cosmic maelstrom of gas and dust is not too far away, with massive stars forming within. The bright, compact, butterfly-shaped nebula (see Featured Image Above) above and left of center likely contains massive stars in a very early stage of formation. This spectacular region of star formation is located in the constellation of Dorado, south of the Tarantula Nebula (NGC 2070) in our satellite galaxy, the Large Magellanic Cloud (LMC), a mere 180,000 light-years distant from Earth. These young stars are emitting intense ultraviolet light, which causes nearby hydrogen gas to glow, with the torrential stellar winds carving out ridges, arcs, and filaments from the surrounding material. Their energetic radiation and powerful stellar winds sculpt the gas and dust and power the glow of this ionized hydrogen HII region, surrounded by cooler, neutral hydrogen, entered into the Henize catalogue of emission stars and nebulae in the Magellanic Clouds, as N159.

At the heart of this cosmic cloud lies the Papillon Nebula, a butterfly-shaped region of nebulosity. Resolved for the first time in Hubble images, this small, dense object is classified as a High-Excitation Blob, and is thought to be tightly linked to the early stages of massive star formation. Reasons for the bipolar shape of the Papillon Nebula are currently unknown, but might indicate the presence of unseen high-mass stars and a thick gaseous disk. This colour image (hi-res version) was made from separate exposures taken in the visible and near-infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS).

The Guna, known as Kuna prior to an orthographic reform in 2010, and historically as Cuna, are an indigenous people of Panama and Colombia. In the Kuna language, they call themselves Dule or Tule, meaning "people," and the name of the language in Kuna is Dulegaya, literally "people-mouth." Most Gunas live on small islands off the coast of the comarca of Kuna Yala known as the San Blas Islands. Each community has its own political organization, led by a saila, who is traditionally both the political and religious leader of the community; he memorizes songs which relate the sacred history of the people and transmits them to the people. Traditionally, Guna families are matrilinear, with the groom moving to become part of the bride's family and taking the last name of the bride as well.

The Tadpoles of IC 410.

This close-up shows the otherwise faint emission nebula IC 410 in striking false-colours, featuring two remarkable inhabitants of the cosmic pond of gas and dust above and left of centre: the tadpoles of IC 410. The narrowband data traces atoms in the nebula, with emission from sulfur atoms in red, hydrogen atoms in green, and oxygen in blue. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars that energizes the glowing gas. Composed of denser cooler gas and dust the tadpoles are around 10 light-years long, potential sites of ongoing star formation, and sculpted by wind and radiation from the cluster stars, their tails trail away from the cluster's central region. IC 410 lies some 12,000 light-years away, toward the constellation Auriga.

The current flag of Myanmar was adopted on 21 October 2010. The new flag was introduced along with implementing changes to the country's name, which were laid out in the 2008 Constitution. The design of the flag has three horizontal stripes of yellow, green and red with a five-pointed white star in the middle. The three colours of the stripes are meant to symbolise solidarity, peace and tranquility, and courage and decisiveness. The white star that symbolised the Union of Burma.

The Elgin Marbles are a collection of Classical Greek marble sculptures made under the supervision of Phidias and his assistants in c. 447 to 438 BC; originally part of the temple of the Parthenon. From 1801 to 1812, agents of Thomas Bruce, 7th Earl of Elgin removed about half of the surviving sculptures and transported them to Britain. The half not removed is now displayed in the Acropolis Museum. In Britain, the acquisition of the collection was not supported by some, and the Earl's actions was likened to vandalism. Following a public debate in Parliament and its subsequent exoneration of Elgin, he sold the Marbles to the British government in 1816. They were then passed to the British Museum, where they are now on display in the purpose-built Duveen Gallery.
