nebulae
Interstellar gas formations
Nebulae is the plural of nebula, a vast cloud of gas and dust in space.
Some nebulae are stellar nurseries where new stars form; others are the remnants of dying stars.
The term comes from the Latin word for cloud or mist.
The Hubble telescope captured stunning images of distant nebulae.
The anglicized plural nebulas is also used.
