The Superwind Galaxy NGC 4666 is located ~ 80 million ly from Earth. Gravitational interactions between NGC 4666 and NGC 4668 (to the lower left) triggered intense star formation.
Galaxy M74.
Bright pink (HII) regions decorating the spiral arms are huge and relatively short-lived, clouds of hydrogen gas which glow due to the strong radiation from hot, young stars embedded within them.
