A Ghost Remains
This composite image shows a small region of the Chandra Deep Field North. The diffuse blue object near the center of the image is believed to be a cosmic ‘ghost’ generated by a huge eruption from a supermassive black hole in a distant galaxy. This X-ray ghost, a.k.a. HDF 130, remains after powerful radio waves from particles traveling away from the black hole at almost the speed of light, have died off.
HDF 130 is more than 10 billion light years away and existed at a time 3 billion years after the Big Bang, when galaxies and black holes were forming at a high rate. Near the center of the X-ray ghost is a radio point source indicating the presence of a growing supermassive black hole.
Asi que la imagen del centro es un agujero negro, lo que no entiendo es que si eso engulle hasta los rayos de luz, como la refleja?. Tendria que ser totalmente negro, como un borron en el espacio donde nada se reflejara, no?:cold:
