Capturan imágenes del agujero negro más extraño



En la página oficial del telescopio espacial Hubble, publicaron la ultima imagen capturada por el artefacto. Se trata de un agujero negro que se ubica en el centro de una pequeña galaxia.

El agujero ha sido considerado único en su tipo, ya que posee un alto grado de luminosidad. Aunque hace años los científicos han estado detrás de su pista, es la primera fotografía en la que se ve más iluminado.

Lo extraño y lo que sorprende a los expertos, es que el agujero termina desafiando y en contra de lo que dictan las leyes de la física.

Por ahora, el compromiso es a seguirle el paso al extraño agujero negro y buscar otros objetos espaciales que puedan mostrar las mismas características e incluso marque más diferencias.



This image taken with the Advanced Camera for Surveys (ACS) onboard the NASA/ESA Hubble Space Telescope captures a galaxy in the Virgo constellation. This camera was installed in 2002, and its wide field of view is double that of its predecessor, capturing superb images with sharp image quality and enhanced sensitivity that can be seen here. The beautiful spiral galaxy visible in the centre of the image is catchily known as RX J1140.1+0307, and it presents an interesting puzzle. At first glance, this galaxy appears to be a normal spiral galaxy, much like the Milky Way, but first appearances can be deceptive! The Milky Way galaxy, like most large galaxies, has a supermassive black hole at its centre, but some galaxies are centred on lighter, intermediate-mass black holes. RX J1140.1+0307 is such a galaxy — in fact, it is centred on one of the lowest black hole masses known in any luminous galactic core. What puzzles scientists about this particular galaxy is that the calculations don’t add up. With such a relatively low mass for the central black hole, models for the emission from the object cannot explain the observed spectrum; unless there are other mechanisms at play in the interactions between the inner and outer parts of the accretion disc surrounding the black hole.
