How does gas cycle through galaxies

WebSummary of Galactic Recycling • Stars make new heavy elements by fusion. • Dying stars expel gas and new elements, producing hot bubbles of gas (~106K). These emit X-rays. • This hot gas cools, allowing atomic hydrogen clouds to form (~100-10,000 K). This hydrogen emits at 21-cm wavelength emission line.

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. WebThe bar structure is believed to act as a type of stellar nursery, channeling gas inwards from the spiral arms through orbital resonance, fueling star birth in the vicinity of its center.
