He said that scientists assume most stellar - remnant black holes — which result from the collapse of massive stars at the end of their lives — will be about the same mass as our sun.

Sobral adds: «But star formation at this rate leads to a lot of massive, short - lived stars coming into being, which explode as supernovae a few million years later.

Elements heavier than hydrogen and helium were more abundant later in the star - forming boom as more massive stars ended their lives early and enriched the galaxy with material that served as the building blocks of planets and even life on Earth.

It is unfortunate, then, that some of the easiest planets to detect are the so - called hot Jupiters: massive bodies hugging tight to their host stars and therefore subject to extremely high (and probably life - negating) temperatures.
