How does gas cycle through galaxies
WebJul 4, 2024 · The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun. The leftover material from the star's birth is used to create planets and other objects that orbit the central star. WebApr 11, 2024 · Gas from intergalactic space constantly falls onto the Milky Way due to its gravity, adding new gas to the interstellar medium. Conversely, in giant molecular clouds where gas collects together due to gravity, the gas can collapse to form new stars, as discussed in The Birth of Stars and the Discovery of Planets outside the Solar System.

This process allows galaxies to build successive generations of stars stretching over billions of years.
WebSep 15, 2016 · The reason galaxies die, according to new research, lies with the supermassive black holes that lurk at the centers of dead galaxies. In a recent paper, scientists revealed these black holes are spewing out energy that heats up gas in lifeless galaxies—gas that otherwise would cool and condense into new generations of stars.
