“Joya cósmica”: Un telescopio en Chile capta una galaxia con un agujero negro supermasivo



El telescopio VLT (Very Large Telescope) del Observatorio Europeo Austral (ESO, por sus siglas en inglés), situado en el desierto Atacama en Chile, ha captado una impresionante imagen de una galaxia espiral, informa este miércoles la página web del organismo.

La foto de la galaxia NGC 3981, que se encuentra en la constelación de Crater, fue tomada en mayo de este año en el marco del proyecto del ESO denominado Joyas Cósmicas. La imagen fue obtenida con ayuda del reductor focal y espectrógrafo de baja dispersión FORS2 instalado en el VLT.

El reductor de alta sensibilidad permitió al telescopio captar los brazos espirales de la galaxia con regiones de formación estelar y su disco central luminoso, que alberga jóvenes estrellas calientes. Asimismo, en el centro luminoso de NGC 3981 se observa la existencia de una región altamente energética que contiene un agujero negro supermasivo.

Además, en la foto se pueden ver unas estructuras espirales periféricas estiradas hacia el exterior de la galaxia, lo que podría ser una señal de un pasado encuentro galáctico.

NGC 3981 se encuentra a unos 65 millones años luz de nuestro planeta y forma parte de un grupo de la gran Nube de Cráter, que es, por su parte, un componente más pequeño del Supercúmulo de Virgo, una gran colección de galaxias que alberga nuestra Vía Láctea.

    One thing I would really like to touch upon is that fat reduction plan fast may be possible by the proper diet and exercise. Someone’s size not merely affects the look, but also the entire quality of life. Self-esteem, melancholy, health risks, along with physical abilities are impacted in fat gain. It is possible to do everything right but still gain. In such a circumstance, a condition may be the reason. While an excessive amount of food rather than enough workout are usually responsible, common health concerns and popular prescriptions might greatly enhance size. Thanks a bunch for your post in this article.

When Associate Certification are a great way to start, completing ones Bachelors reveals many entrance doors to various professions, there are numerous on-line Bachelor Course Programs available coming from institutions like The University of Phoenix, Intercontinental University Online and Kaplan. Another issue is that many brick and mortar institutions present Online variations of their college diplomas but generally for a extensively higher cost than the corporations that specialize in online degree programs.
