Hola amigos: A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa que el Telescopio Espacial Hubble captó la Galaxia conocida como "Pequeño Sombrero" más conocida como NGC 7814.
Las galaxias pueden tomar muchas formas y ser orientada modo alguno en relación con nosotros en el cielo. Esto puede hacer que sea difícil de averiguar su morfología actual, como una galaxia puede ver muy distinta desde diferentes puntos de vista. Un caso especial es cuando tenemos la suerte de observar una galaxia espiral directamente desde su borde, que nos proporciona una vista espectacular como el que se ve en esta foto de la semana.
Se trata de NGC 7814, también conocido como el ". Little Sombrero" Su tocayo más grande, la Galaxia del Sombrero, es otro ejemplo impresionante de borde-en galaxia - de hecho, el "Little Sombrero" es aproximadamente el mismo tamaño que su brillante tocayo a unos 60.000 años luz de diámetro, pero ya que se encuentra más lejos, y por lo que parece más pequeño en el cielo.
Hubble's Little Sombrero
Galaxies can take many shapes and be oriented any
way relative to us in the sky. This can make it hard to figure out their actual
morphology, as a galaxy can look very different from different viewpoints. A
special case is when we are lucky enough to observe a spiral galaxy directly
from its edge, providing us with a spectacular view like the one seen in this
picture of the week.
This is NGC 7814, also known as the “Little Sombrero.” Its larger namesake, the Sombrero Galaxy, is another stunning example of an edge-on galaxy — in fact, the “Little Sombrero” is about the same size as its bright namesake at about 60,000 light-years across, but as it lies farther away, and so appears smaller in the sky.
NGC 7814 has a bright central bulge and a bright halo of glowing gas extending outwards into space. The dusty spiral arms appear as dark streaks. They consist of dusty material that absorbs and blocks light from the galactic center behind it. The field of view of this NASA/ESA Hubble Space Telescope image would be very impressive even without NGC 7814 in front; nearly all the objects seen in this image are galaxies as well.
