Webb reveals warm space dust in far-off Makani galaxy’s circumgalactic medium

In a distant galaxy called Makani, particles of dust were warmed by the light of newborn stars before being flung out into space by a massive starburst-driven wind. Over the course of 100 million years, the dust traveled farther and farther from Makani’s center, ultimately ending up in the reservoir of hot gas that surrounds a galaxy, known as the circumgalactic medium (CGM).
