GALAXIA NGC 1097.......UNA GRAN AGRUPACIÓN DE ESTRELLAS EN FORMA ESPIRAL CON UN HOYO NEGRO AL CENTRO

Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido de la NASA una espectacular vista panoràmica de la GALAXIA NGC 1097 , fotografiada por el Telescopio Espacial Spitzer . Aquí apreciamos en la vista panóramica la GALAXIA NGC 1097, es una agrupación de estrellas en forma espiral y con un OJO CENTRAL según los científicos ese brillante centro que apreciamos es un Monstruoso Agujero Negro supermasivo, y es tan inmenso que es 100 veces mayor que nuestro Sistema Solar ; en la parte azul de la izquierda se aprecia una galaxia mas pequeña , que actúa como una compañera, esta, está envuelta en los grandes brazos de la Galaxia NGC 1097, está ubicada 50 millones de años luz de la tierra.

Coiled Creature
NASA's Spitzer Space Telescope has imaged a wild creature of the dark -- a coiled galaxy with an eye-like object at its center.
The 'eye' at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white.

The galaxy, called NGC 1097 and located 50 million light-years away, is spiral-shaped like our Milky Way, with long, spindly arms of stars.

The black hole is huge, about 100 million times the mass of our sun, and is feeding off gas and dust, along with the occasional unlucky star. Our Milky Way's central black hole is tame in comparison, with a mass of a few million suns.

The ring around the black hole is bursting with new star formation. An inflow of material toward the central bar of the galaxy is causing the ring to light up with new stars. And, the galaxy's red spiral arms and the swirling spokes seen between the arms show dust heated by newborn stars. Older populations of stars scattered through the galaxy are blue. The fuzzy blue dot to the left, which appears to fit snugly between the arms, is a companion galaxy. Other dots in the picture are either nearby stars in our galaxy, or distant galaxies.

This image was taken during Spitzer's cold mission, before it ran out of liquid coolant. The observatory's warm mission is ongoing, with two infrared channels operating at about 30 degrees Kelvin (-406 degrees Fahrenheit).
