MASSIVE stars undergo violent deaths, forming the type II supernovae believed to result from gravitational collapse of the stellar cores. Such an event may be recognised by the optical outburst which occurs when

The life and death of stars. Nothing brightens the cosmos like a supernova. The demise of a star releases enormous quantities energy and material that's like pollen for a new generation of stars, planets and life itself. Ultimately, humankind's fascination with the stars in the heavens is ...

All that remains of a massive star that ended its life in a powerful explosion around 11,000 years ago is this wispy structure of pink and orange clouds. Whenmassive stars reach the end of their life, they often go out with a bang, in anoutburstcalled asupernova. These massive ...
really massive stars are rare (seeThe Stars: A Celestial Census). This is similar to the music business where only a few musicians ever become superstars. Furthermore, many stars with an initial mass much greater than 1.4MSunwill be reduced to that level by the time they die. For example...
Death of Massive Stars As iron core grows, the immense weight is supported by electron degeneracy pressure--ie, electron gas Eventually the electron gas is compressed to the point that the electron degeneracy pressure is overcome by gravity--electrons combine with protons forming neutrons and emittin...
there is a cluster of massive, hot young stars that are only a few million years old. Above and to the right of the cluster, there is an isolated star surrounded by a ring of gas. Perpendicular to the ring and on either side of it, there are two bluish blobs of gas. The ring ...
Using the ALMA, astronomers have observed star birth and potential death sites in a galaxy 13.2 billion light-years away. Their observations revealed an ionization process by newly formed stars and a massive cavity that might represent a “superbubble” from supernova explosions, marking ...
The death of a star.The death of a star.The article offers information on the death of stars. The most massive stars end their brief lives of a few million years in cataclysmic explosions that we call supernovae. But dwarf stars like the Sun end their 10-billion-year lifetimes in a mu...
