Hubble Space Telescope captures image of ionized hydrogen glow in Puppis constellation's nebula RCW 7, revealing newborn stars.

Hubble Space Telescope captured an image of nebula RCW 7, 5,300 light-years away in the Puppis constellation. The newborn stars within the nebula emit ultraviolet radiation that ionizes hydrogen, causing a pinkish glow. These massive protostars transform the nebula into a H II region, as gravity causes molecular clouds to collapse into young, developing stars surrounded by leftover gas and dust.
