VLT clears up dusty mystery
Paris (SPX) Jul 11, 2014
The origin of cosmic dust in galaxies is still a mystery [1]. Astronomers know that supernovae may be the primary source of dust, especially in the early Universe, but it is still unclear how and where dust grains condense and grow. It is also unclear how they avoid destruction in the harsh environment of a star-forming galaxy. But now, observations using ESO's VLT at the Paranal Observatory in northern Chile are lifting the veil for the first time. An international team used the X-shooter spectro ... read more
