A region of space is filled with stars and clumps of glowing orange and tan dust. A small portion of the sky at the center of the image is outlined with a white box. The background of the image is filled with stars and galaxies of various shapes and colors.

Summary

Planet-building material found even in environments lacking the needed ingredients

The early universe may have been poor in heavy elements, but it was rich in creativity. In environments that lacked many of the ingredients astronomers associate with dust and planets today, new research is showing stars still found ways to build solid material.

Using NASA’s James Webb Space Telescope, astronomers have found unexpected types of dust in the nearby dwarf galaxy Sextans A, showing that stars were able to assemble solid grains from limited ingredients and offering a new window into how the first dusty galaxies took shape.
