This ESO Picture of the Week shows the centre of a galaxy named NGC 5643. This galaxy is located 55 million light-years from Earth in the constellation of Lupus (The Wolf), and is known as a Seyfert galaxy. Seyfert galaxies have very luminous centres — thought to be powered by material being accreted onto a supermassive black hole lurking within — that can also be shrouded and obscured by clouds of dust and intergalactic material.

Water is a key molecule to probe dense and warm regions in the interstellar medium, because of its chemistry as well as its coupling to the far-infrared. This work presents the first detection of the ortho-H2O 4_23 – 3_30 transition at 448 GHz in space. Continue reading
An international team of astronomers lead by the spanish astronomer Santiago García-Burillo (OAN, Madrid), and with the participation of CAB scientists (Almudena Alonso Herrero and Luis Colina), have been able to resolve for the first time the dusty torus around the massive black hole in the nucleus of the nearby active galaxy NGC 1068.
