Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido de la Agencia espacial NASA una belleza sin igual de la Supernova Remnant SN 1006, con ocasión de celebrar el 50 Aniversario de la Investigación Espacial por Rayos X, y se ha tomado como ejemplo la Supernova Remanente SN 1006. Constituye un asombroso adelanto en medio siglo.
Cuando el objeto nosotros ahora llamado SN 1006 aparecido durante el 1 de mayo de 1006 el Año de Cristo., era mucho más brillante que el planeta Venus y visible durante el día durante semanas. Astrónomos en China, Japón, Europa, y el mundo árabe todos han documentado esta vista espectacular. Con el advenimiento de la Era Espacial en los años 1960, los científicos fueron capaz de lanzar instrumentos y detectores encima de la atmósfera de la Tierra para observar el universo en las longitudes de onda que son bloqueadas de la tierra, incluyendo rayos X. SN 1006 era una de las fuentes de rayo X más débiles descubiertas por la primera generación de satélites de rayo X.

Supernova Remnant SN 1006
This year, astronomers around the world have been celebrating the 50th
anniversary of X-ray astronomy. Few objects better illustrate the
progress of the field in the past half-century than the supernova
remnant known as SN 1006.
When the object we now call SN 1006 first appeared on May 1, 1006 A.D., it was far brighter than Venus and visible during the daytime for weeks. Astronomers in China, Japan, Europe, and the Arab world all documented this spectacular sight. With the advent of the Space Age in the 1960s, scientists were able to launch instruments and detectors above Earth's atmosphere to observe the universe in wavelengths that are blocked from the ground, including X-rays. SN 1006 was one of the faintest X-ray sources detected by the first generation of X-ray satellites.
A new image of SN 1006 from NASA's Chandra X-ray Observatory reveals this supernova remnant in exquisite detail. By overlapping ten different pointings of Chandra's field-of-view, astronomers have stitched together a cosmic tapestry of the debris field that was created when a white dwarf star exploded, sending its material hurtling into space. In this new Chandra image, low, medium, and higher-energy X-rays are colored red, green, and blue respectively.
The new Chandra image provides new insight into the nature of SN 1006, which is the remnant of a so-called Type Ia supernova. This class of supernova is caused when a white dwarf pulls too much mass from a companion star and explodes, or when two white dwarfs merge and explode. Understanding Type Ia supernovas is especially important because astronomers use observations of these explosions in distant galaxies as mileposts to mark the expansion of the universe.
The new SN 1006 image represents the most spatially detailed map yet of the material ejected during a Type Ia supernova. By examining the different elements in the debris field -- such as silicon, oxygen, and magnesium -- the researchers may be able to piece together how the star looked before it exploded and the order that the layers of the star were ejected, and constrain theoretical models for the explosion.
Scientists are also able to study just how fast specific knots of material are moving away from the original explosion. The fastest knots are moving outward at almost eleven million miles per hour, while those in other areas are moving at a more leisurely seven million miles per hour. SN 1006 is located about 7,000 light years from Earth. The new Chandra image of SN 1006 contains over eight days worth of observing time by the telescope. These results were presented at a meeting of High Energy Astrophysics Division of the American Astronomical Society in Monterey, CA.
