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.
