Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido de la Agencia Espacial NASA, una espectacular vista de la explosión masiva de una estrella denominada : SNR 0519-69.0, que sucedió en la Galaxia La Gran Nube de Magallanes, que es una galaxia muy próxima a nuestra Vía Láctea.
Esta maravillosa vista captada por los telescopios de NASA, nos enriquecen la celebración del Año Internacional de la Luz, y las Tecnologías basadas en la Luz; proclamado por las Naciones Unidos el 19 de enero del 2015.
Chandra Celebrates the International Year of Light
The year of 2015 has been declared the International Year of Light (IYL) by
the United Nations. Organizations, institutions, and individuals involved in the
science and applications of light will be joining together for this yearlong
celebration to help spread the word about the wonders of light.
NASA’s Chandra X-ray
Observatory explores the universe in X-rays, a high-energy form of light.
By studying X-ray data and comparing them with observations in other types of
light, scientists can develop a better understanding of objects likes stars and
galaxies that generate temperatures of millions of degrees and produce
X-rays.
To recognize the start of IYL, the Chandra X-ray Center is releasing a set of
images that combine data from telescopes tuned to different wavelengths of
light. From a distant galaxy to the relatively nearby debris field of an
exploded star, these images demonstrate the myriad ways that information about
the universe is communicated to us through light.
In this image, an expanding shell of debris called SNR 0519-69.0 is left
behind after a massive star exploded in the Large Magellanic Cloud, a satellite
galaxy to the Milky Way. Multimillion degree gas is seen in X-rays from Chandra,
in blue. The outer edge of the explosion (red) and stars in the field of view
are seen in visible light from the Hubble Space Telescope.

Chandra Celebrates the International Year of Light
To celebrate the International Year of Light, five
Chandra images (M51, SNR E0519-69.0, MSH 11-62, Cygnus A, and RCW 86) have been
released.

In many ways, astronomy uses the science of light. By building telescopes
that can detect light in its many forms, from radio waves on one end of the
“electromagnetic spectrum” to gamma rays on the other, scientists can get a
better understanding of the processes at work in the Universe.

To recognize the start of IYL, the Chandra X-ray Center is releasing a set of
images that combine data from telescopes tuned to different wavelengths of
light. From a distant galaxy to the relatively nearby debris field of an
exploded star, these images demonstrate the myriad ways that information about
the Universe is communicated to us through light.
The images, beginning at the upper left and moving clockwise, are:
Messier 51 (M51): This galaxy, nicknamed the “Whirlpool,” is
a spiral galaxy, like our Milky Way, located about 30 million light years from
Earth. This composite image combines data collected at X-ray wavelengths by
Chandra (purple), ultraviolet by the Galaxy Evolution Explorer (GALEX, blue);
visible light by Hubble (green), and infrared by Spitzer (red).
SNR 0519-69.0: When a massive star exploded in the Large
Magellanic Cloud, a satellite galaxy to the Milky Way, it left behind an
expanding shell of debris called SNR 0519-69.0. Here, multimillion degree gas is
seen in X-rays from Chandra (blue). The outer edge of the explosion (red) and
stars in the field of view are seen in visible light from Hubble.
MSH 11-62: When X-rays, shown in blue, from Chandra and
XMM-Newton are joined in this image with radio data from the Australia Telescope
Compact Array (pink) and visible light data from the Digitized Sky Survey (DSS,
yellow), a new view of the region emerges. This object, known as MSH 11-62,
contains an inner nebula of charged particles that could be an outflow from the
dense spinning core left behind when a massive star exploded.
RCW 86: This supernova remnant is the remains of an exploded
star that may have been witnessed by Chinese astronomers almost 2,000 years ago.
Modern telescopes have the advantage of observing this object in light that is
completely invisible to the unaided human eye. This image combines X-rays from
Chandra (pink and blue) along with visible emission from hydrogen atoms in the
rim of the remnant, observed with the 0.9-m Curtis Schmidt telescope at the
Cerro Tololo Inter-American Observatory (yellow).
Cygnus A: This galaxy, at a distance of some 700 million
light years, contains a giant bubble filled with hot, X-ray emitting gas
detected by Chandra (blue). Radio data from the NSF’s Very Large Array (red)
reveal “hot spots” about 300,000 light years out from the center of the galaxy
where powerful jets emanating from the galaxy’s supermassive black hole end.
Visible light data (yellow) from both Hubble and the DSS complete this view.
In addition to these newly released images, the Chandra X-ray Center has
created a new online repository of images called “Light: Beyond the Bulb” for
IYL. This project places astronomical objects in context with light in other
fields of science and research.
NASA's Marshall Space Flight Center in Huntsville, Alabama, manages the
Chandra program for NASA's Science Mission Directorate in Washington. The
Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, controls
Chandra's science and flight operations.
