Star forming regions form stars in associations or clusters as a consequence of the gravitational collapse of clouds. Typically, in the Milky Way star forming regions form hundreds to few thousands of stars. However, there exist also very massive star forming regions which form tens to hundreds of thousands stars, together with some of the most massive stars known in» Read more

Massive stars are enormous chemical laboratories where heavy chemical elements are synthesized. For instance, the alpha-elements (O, Mg, Si, Ca, and Ti) are produced by nucleosynthetic processes in the interior of massive stars. Moreover, the lifetime of massive stars is much shorter than that of low mass stars: few million years for the former compared to several billion of years» Read more

Supernovae explosions are among the most spectacular phenomena in the Universe. These cosmic fireworks mark the death of massive stars, releasing in few seconds the same amount of energy the Sun releases in its whole evolution. Besides, the outer envelopes of the exploding stars are ejected with velocities in excess of 10000 km/sec, forming a supernova remnants. Several supernova» Read more
