The problem of our Galaxy is that when you try to get to the heart of it you end up rather frustrated. As well as being in a difficult position to study it,- right in the plane, and about half way from the centre to the edge, the main obstacle is interstellar dust which blocks our line of sight to the Galactic nucleus, where there is a very strong indication that a

By IVÁN JIMÉNEZ Twenty years ago an exceptional discovery blurred forever the boundary between what we call stars and what we call planets. A star is characterized by producing nuclear reactions in its interior. However in 1995 a group of researchers of the Instituto de Astrofísica de Canarias (IAC), among them Maria Rosa Zapatero Osorio (now at the Centre for Astrobiology (CAB-CSIC-INTA) discovered an object which appeared to be a star, but without sufficient mass to produce significant nuclear reactions. Although it was given the name Teide-1, the scientists had in fact found a type of

The European Week of Astronomy and Space Science EWASS 2015 which is being celebrated during this week on the Guajara Campus of the University of La Laguna (Tenerife) includes 40 parallel sessions in which the lates advances in astronomy are presented.
