The chemical elements in these grains are forged inside stars and are scattered across the cosmos when the stars die, most spectacularly in supernova explosions, the final fate of short-lived, massive stars.

Determining the timing of this \u201ccosmic dawn\u201d is one of the holy grails of modern astronomy, and it can be indirectly probed through the study of early interstellar dust.<\/p>\n<p dir=\"ltr\">The team estimates that A2744_YD4 contained an amount of dust equivalent to 6 million times the mass of our Sun, while the galaxy\u2019s total stellar mass \u2014 the mass of all its stars \u2014 was 2 billion times the mass of our Sun. The team also measured the rate of star formation in A2744_YD4 and found that stars are forming at a rate of 20 solar masses per year \u2014 compared to just one solar mass per year in the Milky Way <a href=\"#3\">[3]<\/a>.<\/p>\n<p dir=\"ltr\" style=\"padding-left: 30px;\">\u201c<em>This rate is not unusual for such a distant galaxy, but it does shed light on how quickly the dust in A2744_YD4 formed<\/em>,\u201d explains Richard Ellis (ESO and University College London), a co-author of the study. \u201c<em>Remarkably, the required time is only about 200 million years \u2014 so we are witnessing this galaxy shortly after its formation<\/em>.\u201d<\/p>\n<p dir=\"ltr\">This means that significant star formation began approximately 200 million years before the epoch at which the galaxy is being observed. This provides a great opportunity for ALMA to help study the era when the first stars and galaxies \u201cswitched on\u201d \u2014 the earliest epoch yet probed. Our Sun, our planet and our existence are the products \u2014 13 billion years later \u2014 of this first generation of stars.
