![]() ![]() Wikimedia Commons users Kieff and LucasVB, annotations by E. greatest amounts of heavy elements the fastest, but the less massive ones are more numerous and are responsible for large fractions of the lower-mass elements found in nature. The next step up in mass, to Sun-like stars, makes a big difference for a large slew of elements present in our Solar System today.ĭifferent colors, masses and sizes of main-sequence stars. About 80-90% of the stars ever created are still fusing hydrogen into helium, and will remain doing so until more time than the present age of the Universe has gone by. The more numerous, less massive stars will burn through their fuel slowly, living extremely long times. During a starburst, that gas gets rapidly converted into stars of all masses and in enormous varieties of groupings: singles, binaries, trinaries, all the way up to at least sextuple systems. These events will gravitationally perturb the hydrogen gas present within a galaxy, triggering an event known as a starburst. Over the history of the Universe, the most massive periods of star formation occur when galaxies interact, merge together, or fall into massive groups and clusters. X-ray (NASA/CXC/Virginia/A.Reines et al) Radio (NRAO/AUI/NSF) Optical (NASA/STScI) This can result in severely increased rates of star-formation, similar to what we observe inside the nearby galaxy Henize 2-10, located 30 million light years away. hydrogen and helium gas present within them. When major mergers of similarly-sized galaxies occur in the Universe, they form new stars out of the. ![]()
