Turbulent Star-Birth Region Selection Case For The iPad Mini

In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal. Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away near the Tarantula nebula, one of the most active star-forming regions in our Local Group of galaxies. The three-dimensional-looking image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under torrential ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars. The high-energy radiation blazing out from clusters of hot young stars already born in NGC 2074 is sculpting the wall of the nebula by slowly eroding it away. Another young cluster may be hidden beneath a circle of brilliant blue gas at center, bottom. In this approximately 100-light-year-wide fantasy-like landscape, dark towers of dust rise above a glowing wall of gases on the surface of the molecular cloud. The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri. The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution. Dwarf galaxies like the LMC are considered to be the primitive building blocks of larger galaxies. This representative color image was taken on August 10, 2008, with Hubble's Wide Field Planetary Camera 2. Red shows emission from sulfur atoms, green from glowing hydrogen, and blue from glowing oxygen. Source: NASA.

Summer jobs steer teens away from violence

Science Focus

original post »

Violent crime in the United States kills 150 people every day, injuring 6,000 more. Disadvantaged minority youth are disproportionately affected, being more likely to be both perpetrators and victims. This is a population desperately in need of interventions to reduce violent crime.

Conventional wisdom says that if you want to reduce crime, you need to ensure that everyone has a job. In theory, unemployment causes psychological stress, weakens social bonds, and causes people to perceive punishment for crime as less costly, since there’s less to lose. However, empirical social science studies on the impact of youth employment programs don’t have such clear-cut results. Many programs don’t lower crime at all, and those that do are so intense that the costs outweigh the benefits. The theory is sound, but the results don’t show.

A recent randomized, controlled trial published in Science found that certain kinds of employment programs might have an effect after all, if they target the right problems at the right time. Research in medicine and education suggests that intervening before a problem develops leads to better outcomes, with less intensive treatment.

Dumbbell Nebula in Taurus Oval Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space

Dumbbell Nebula in Taurus Oval Stickers

Galaxies, Stars and Nebulae series A great photo from deep space featuring the Dumbbell Nebula - also known as Messier 27 or NGC 6853. It's a typical planetary nebula and is located in the constellation Vulpecula (The Fox).

The distance is rather uncertain, but is believed to be around 1,200 light-years. It was first described by the French astronomer and comet hunter Charles Messier who found it in 1764 and included it as no. 27 in his famous list of extended sky objects.

Despite its class, the Dumbbell Nebula has nothing to do with planets. It consists of very rarefied gas that has been ejected from the hot central star (well visible on this photo), now in one of the last evolutionary stages. The gas atoms in the nebula are excited (heated) by the intense ultraviolet radiation from this star and emit strongly at specific wavelengths.

This image is the beautiful by-product of a technical test of some FORS1 narrow-band optical interference filters. They only allow light in a small wavelength range to pass and are used to isolate emissions from particular atoms and ions.

In this three-colour composite, a short exposure was first made through a wide-band filter registering blue light from the nebula. It was then combined with exposures through two interference filters in the light of double-ionized oxygen atoms and atomic hydrogen. They were colour-coded as “blue”, “green” and “red”, respectively, and then combined to produce this picture that shows the structure of the nebula in “approximately true” colours.

The Winter Shower

more »
Known in the north as a winter meteor shower, the 2014 Geminids rain down on this rugged, frozen landscape. The scene was recorded from the summit of Mt. Changbai along China's northeastern border with North Korea as a composite of digital frames capturing bright meteors near the shower's peak. Orion is near picture center above the volcanic cater lake. The shower's radiant in the constellation Gemini is to the upper left, at the apparent orgin of all the meteor streaks. Paying the price for such a dreamlike view of the celestial spectacle, photographer Jia Hao reports severe wind gusts and wintery minus 34 degree C temperatures near the summit.

Supernova discoveries are reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams, which sends out a circular with the name it assigns to it. The name is the year of discovery, immediately followed by a one or two-letter designation. The first 26 supernovae of the year are designated with a capital letter from A to Z. Afterward pairs of lower-case letters are used: aa, ab, and so on.[36] Since 2000, professional and amateur astronomers find several hundreds of supernovae each year (572 in 2007, 261 in 2008, 390 in 2009). For example, the last supernova of 2005 was SN 2005nc, indicating that it was the 367th[nb 1] supernova found in 2005.[37][38] Historical supernovae are known simply by the year they occurred: SN 185, SN 1006, SN 1054, SN 1572 (Tycho's Nova) and SN 1604 (Kepler's Star). Since 1885 the letter notation has been used, even if there was only one supernova discovered that year (e.g. SN 1885A, 1907A, etc.)—this last happened with SN 1947A. "SN", for SuperNova, is a standard prefix. Until 1987, two-letter designations were rarely needed; since 1988, however, they have been needed every year.

Fires of the Flame Nebula - in Orion Rectangular Sticker

tagged with: breathtaking astronomy images, hfflmnb, star forming, orion constellation, young stars clusters, orion the hunter, flame nebula, awesome space picture, heavens, orions belt, european southern observatory, eso, vista

Galaxies, Stars and Nebulae series A gorgeous outer space picture featuring the spectacular star-forming region known as the Flame Nebula, or NGC 2024, in the constellation of Orion (the Hunter) and its surroundings.

In views of this evocative object in visible light the core of the nebula is completely hidden behind obscuring dust, but in this VISTA view, taken in infrared light, the cluster of very young stars at the object’s heart is revealed. The wide-field VISTA view also includes the glow of the reflection nebula NGC 2023, just below centre, and the ghostly outline of the Horsehead Nebula (Barnard 33) towards the lower right.

The bright bluish star towards the right is one of the three bright stars forming the Belt of Orion. The image was created from VISTA images taken through J, H and Ks filters in the near-infrared part of the spectrum.

The image shows about half the area of the full VISTA field and is about 40 x 50 arcminutes in extent. The total exposure time was 14 minutes and was the first to be released publicly from VISTA, the world’s largest survey telescope.
