ASTRONOMY: Hubble Serves Up a Holiday Snow Angel

Hi My Friends: A VUELO DE UN QUINDE EL BLOG., Hubble’s Wide Field Camera 3 has captured this image of a giant cloud of hydrogen gas illuminated by a bright young star. The image shows how violent the end stages of the star-formation process can be, with the young object shaking up its stellar nursery.

This image shows Sh 2-106, or S106 for short. This is a compact star forming region in the constellation Cygnus (The Swan). A newly-formed star called S106 IR is shrouded in dust at the centre of the image, and is responsible for the the surrounding gas cloud’s hourglass-like shape and the turbulence visible within. Light from glowing hydrogen is coloured blue in this image. The image combines observations from the Hubble Space Telescope (in the centre) with images from the National Astronomical Observatory of Japan’s Subaru Telescope to extend the field of view around the edges of the image.

This picture, there is nothing peaceful about star forming region Sh 2-106, or S106 for short. A devilish young star, named S106 IR, lies in it and ejects material at high speed, which disrupts the gas and dust around it. The star has a mass about 15 times that of the Sun and is in the final stages of its formation. It will soon quieten down by entering the main sequence, the adult stage of stellar life.
For now, S106 IR remains embedded in its parent cloud, but it is rebelling against it. The material spewing off the star not only gives the cloud its hourglass shape but also makes the hydrogen gas in it very hot and turbulent. The resulting intricate patterns are clearly visible in this Hubble image. This image shows a ground-based telescope image of the region around star forming region Sh 2-106, or S106 for short. S106 is a compact star-forming region in the constellation of Cygnus (the Swan). Credits: NASA/ESA/Digitized Sky Survey 2 (Acknowledgement: Davide De Martin).

The young star also heats up the surrounding gas, making it reach temperatures of 10 000 degrees Celsius. The star’s radiation ionises the hydrogen lobes, making them glow. The light from this glowing gas is coloured blue in this image.
Separating these regions of glowing gas is a cooler, thick lane of dust, appearing red in the image. This dark material almost completely hides the ionising star from view, but the young object can still be seen peeking through the widest part of the dust lane.
S106 was the 106th object to be catalogued by the astronomer Steward Sharpless in the 1950s. It is a few thousand light-years distant in the direction of Cygnus (The Swan). The cloud itself is relatively small by the standards of star-forming regions, around 2 light-years along its longest axis. This is about half the distance between the Sun and Proxima Centauri, our nearest stellar neighbour.

Hubble Serves Up a Holiday Snow Angel
The bipolar star-forming region, called Sharpless 2-106, looks like a soaring, celestial snow angel. The outstretched "wings" of the nebula record the contrasting imprint of heat and motion against the backdrop of a colder medium. Twin lobes of super-hot gas, glowing blue in this image, stretch outward from the central star. This hot gas creates the "wings" of our angel. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an "hourglass" shape.

This composite picture was obtained with the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope. It results from the combination of two images taken in infrared light and one which is tuned to a specific wavelength of visible light emitted by excited hydrogen gas, known as H-alpha. This choice of wavelengths is ideal for targetting star-forming regions. The H-alpha filter isolates the light emitted from hydrogen in gas clouds while the infrared light can shine through the dust that often obscures these

ASTRONOMY: Dark Murky Clouds in the Bright Milky Way

Hi my Friends: A VUELO DE UN QUINDE EL BLOG., These dark clouds are so dense that if you were located in the middle of one of them, you wouldn't be able to see anything--no stars, no galaxies, only darkness. This dense material will eventually result in the formation of new stars and planets.

Typically if an astronomer wants to see into or through a thick dark cloud in space, they will use an infrared-sensing telescope. However, in this infrared image from NASA's Wide-field Infrared Survey Explorer, or WISE, there are some clouds that are so cool and thick that even infrared light coming from within or the background can't penetrate them. The black areas in this image -- called infrared dark clouds -- are exceptionally cold, dense cloud cores seen in silhouette against the bright diffuse infrared glow of the plane of the Milky Way galaxy. The clouds are a great example of why it is so useful for astronomers to be able to observe in many different wavelengths of light.

If you were to look at this same region of the sky through a backyard telescope, you would see a sea of stars packed together, similar to the thousands of blue stars seen here. You might also notice small patches of darkness that appear to block out the stars behind them. But what you wouldn't see are these beautiful clouds colored green, yellow and red in this image from WISE. Those are only seen in infrared light. In fact, the places where you see dark patches with your eyes are often the places where WISE sees bright clouds with its infrared "eyes." This is because those clouds are dense enough to block visible light, but not dense enough to block longer wavelengths of infrared light that WISE detects. In addition, they are too cool to shine in visible light but still warm enough to glow brightly in infrared light.

However, the darkest areas here are places where the cloud is extremely compact and chilly, so much so that it is opaque even in the infrared wavelengths that WISE sees. To see them glow, one would need to look in even longer wavelengths, for example those detected by the European Space Agency's Herschel mission, which has important NASA contributions

These dark clouds are so dense that if you were located in the middle of one of them, you wouldn't be able to see anything--no stars, no galaxies, only darkness. This dense material will eventually result in the formation of new stars and planets.

This image was made from observations by all four infrared detectors aboard WISE. Blue and cyan (blue-green) represent infrared light at wavelengths of 3.4 and 4.6 microns, which is primarily light from stars. Green and red represent light at 12 and 22 microns, which is primarily light from warm dust.

JPL manages the Wide-field Infrared Survey Explorer for NASA's Science Mission Directorate, Washington. The principal investigator, Edward Wright, is at UCLA. The mission was competitively selected under NASA's Explorers Program managed by the Goddard Space Flight Center, Greenbelt, Md. The science instrument was built by the Space Dynamics Laboratory, Logan, Utah, and the spacecraft was built by Ball Aerospace & Technologies Corp., Boulder, Colo. Science operations and data processing take place at the Infrared Processing and Analysis Center at the California Institute of Technology in Pasadena. Caltech manages JPL for NASA.

ASTRONOMÍA: UNA ESTRELLA FUGITIVA SURCA A TRAVÉS DEL ESPACIO

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido la información de la NASA sobre el movimiento de alejamiento de la estrella "Zeta Ophiuchi" de su compañera que explotó y la disparó al espacio como una bala, está en la Constelación del Ofiuco y pertenece a la clase de supergigante azul fue captada por el Wide-Field infrared Survey Explorer, y queda a 460 millones de años luz de La Tierra; este es el informe de la NASA:

"Una estrella masiva se aleja volando de su anterior compañera, está surcando el polvo espacial . El resultado es un brillante arco de choque, que se aprecia como un arco amarillo es una nueva imagen tomada por el Wide-field infrared Survey Explorer, o WISE , de la NASA.Aquí en la imagen observamos una fotografía de la Estrella " Zeta Ophiuchi" que surca el espacio cuya masa es más de 20 veces la del El Sol. Fuente: Nasa.

La estrella, llamada Zeta Ophiuchi, es enorme , con un masa de unas 20 veces la de nuestro Sol . En la imagen de WISE , en la que la luz infrarroja ha sido traducida a colores visibles que podemos ver con nuestros ojos , la estrella es el punto azul dentro del arco de choque.

La estrella Zeta Ophiuchi, orbitó en tiempos alrededor de una estrella masiva . Pero cuando la estrella explotó como supernova. Zeta Ophiuchi salió disparada como una bala. Está viajando a unos vertiginosos 24 kilómetros por segundo, dirigiéndose hacia la dirección superior izquierda de la imagen . Mientras la estrella surca el espacio. Sus potentes vientos apartan el gas y el polvo que se encuentra por el camino, formando lo que se denomina un arco de choque.

El material del arco de choque se encuentra tan comprimido que brilla en luz infrarroja detectable por WISE. El efecto es similar a lo que ocurre cuando un barco viaja por el agua, formando una ola delante de él . Este arco de choque está completamente oculto a la luz visible por los humanos . Imágenes infrarrojas como las del WISE son, por lo tanto, importantes para arrojar nueva luz sobre la región.

Según los especialistas que trabajan con el WISE , la Estrella Zeta Ophiuchi está condenada al mismo fin que su vieja compañera : Existirá otros 4 millones de años antes que se consuma todo su "combustible" y explote , convirtiéndose en una supernova.

NASA.............PRIMERAS IMÁGENES DEL OBSERVATORIO "WISE" DE LA GALAXIA ANDRÓMEDA

Hola amigos: A VUELO DE UN QUINDE EL BLOG; la agencia espacial norteamericana NASA , todos los días nos enriquece con sus nuevos descubrimientos espaciales por medio de sus telescopios y observatorios espaciales, nuevamente el Observatorio WISE o Wide-field Infrared Survey Explorer nos muestra en la imagen de nuestra galaxia vecina ANDRÓMEDA.
La imnesa galaxia Andrómeda , nuestra vecina, también conocida como Messier 31 o simplemente M31, es captada por completo en esta nueva imagen del Explorador de Revisión Amplio de campaña Infrarrojo de la NASA, o WISE. El mosaico cubre un equivalente de área con más de 100 lunas llenas, o cinco grados a través del cielo. WISE ha usado todos los cuatro de sus detectores infrarrojos para capturar este cuadro(imagen) (3.4-y la luz de 4.6 micras es coloreado azul; la luz de 12 micras es verde; y la luz de 22 micras es roja). Toques de luz azules maduran estrellas, mientras el polvo de espectáculo amarillo y rojo acalorado por estrellas recién nacidas, masivas.

Our Neighbor Andromeda:

The immense Andromeda galaxy, also known as Messier 31 or simply M31, is captured in full in this new image from NASA's Wide-field Infrared Survey Explorer, or WISE. The mosaic covers an area equivalent to more than 100 full moons, or five degrees across the sky. WISE used all four of its infrared detectors to capture this picture (3.4- and 4.6-micron light is colored blue; 12-micron light is green; and 22-micron light is red). Blue highlights mature stars, while yellow and red show dust heated by newborn, massive stars.

Andromeda is the closest large galaxy to our Milky Way galaxy, and is located 2.5 million light-years from our sun. It is close enough for telescopes to spy the details of its ringed arms of new stars and hazy blue backbone of older stars. Also seen in the mosaic are two satellite galaxies, known as M32, located just a bit above Andromeda to the left of center, and the fuzzy blue M110, located below the center of the great spiral arms. These satellites are the largest of several that are gravitationally bound to Andromeda.

The Andromeda galaxy is larger than our Milky Way and contains more stars, but the Milky Way is thought to perhaps have more mass due to its larger proportion of a mysterious substance called dark matter. Both galaxies belong to our so-called Local Group, a collection of more than 50 galaxies, most of which are tiny dwarf systems. In its quest to map the whole sky, WISE will capture the entire Local Group.

Comet Siding Spring appears to streak across the sky like a superhero in this new infrared image from NASA's Wide-field Infrared Survey Explorer, or WISE. The comet, also known as C/2007 Q3, was discovered in 2007 by observers in Australia. The snowball-like mass of ice and dust spent billions of years orbiting in the deep freeze of the Oort Cloud, a spherical cloud of comets surrounding our solar system. At some point, it got knocked out of this orbit and onto a course that brings it closer to the sun. On October 7, 2009, it passed as close as 1.2 astronomical units from Earth and 2.25 astronomical units from the sun (an astronomical unit is the distance between the sun and Earth).

Now, the comet is leaving the warmer, more hospitable neighborhood of the solar system and heading back out to chillier parts.In this view, longer wavelengths of infrared light are red and shorter wavelengths are blue. The comet appears red because it is more than ten times colder than the surrounding stars, for example, the bright blue star in the foreground.

Colder objects give off more of their light at longer wavelengths. An ice cube, for example, pours out a larger fraction of its light at longer infrared wavelengths than a cup of hot tea emits.A comet like this one can be thought of as a time capsule leftover from the formation of our solar system 4.5 billion years ago. After spending most of its long, lonely life in the darkest, coldest parts of our solar system, it warms up as it approaches the sun.

The sunlight causes it to shed ices and dust in a long tail that trails behind it. Comet Siding Spring, having experienced this "spring" awakening, is glowing in infrared light that WISE can see. Once it moves too far from the sun's warmth and light, it will disappear from view for the foreseeable future.Astronomers will use these measurements to learn about the comet's size, composition, reflectivity, and the size and makeup of the dust particles in its coma (the hazy cloud surrounding its nucleus) and its tail.

WISE data on this and other comets will help unlock clues that lay within these icy time capsules, teaching us about our solar system's evolution.In this image, 3.4-micron light is colored blue; 4.6-micron light is green; 12-micron light is orange; and 22-micron light is red. It was taken on Jan. 10, 2010.
