ALMA sees super stellar nurseries at heart of starburst galaxy

Starburst galaxies transmute gas into new stars up to 1,000 times faster than typical spiral galaxies like the Milky Way. To try and understand why, an international team of astronomers used the Atacama Large Millimeter/submillimetre Array (ALMA) to dissect a cluster of star-forming clouds at the heart of NGC 253 — one of the nearest starburst galaxies.
