ALMA image maps cold gas in galaxy M83

Original: Captured by ALMA, this image of galaxy M83 depicts the light emitted by cold gas molecules, the ingredients of star form

Astronomers using the ALMA observatory have released an image of the southern spiral galaxy Messier 83 showing light emitted by cold molecular gas, the raw material for star formation. The Southern European Observatory says such images allow researchers to map how the density and temperature of gas clouds vary across different regions of a galaxy, offering insight into where new stars are born.

Why now: Space enthusiasts are sharing striking new ALMA imagery that reveals the star-forming raw material inside a nearby galaxy.
