| nebulizer |
A Nebulizer is a device used to reduce a liquid to an extremely fine cloud, especially for delivering medication to the deep part of the respiratory tract. A nebulizer can be a very useful tool for those with asthma or allergies, where it is vital that the effective drugs for the condition be delivered directly to lung tissues.

| nebulae |
Before the `Great Debate', this term referred to any resolved nebulosity observed in the sky. It had also been noticed that a there were different types of nebulae (singular: nebula), one of which had spiral structure and so were referred to as "spiral nebulae." Today "spiral nebulae" are referred to as "spiral galaxies" and "nebulae" refer to large gas and dust clouds that populate a galaxy.

| nebula |
The term originally applied to any extended (ie, fuzzy, non-stellar) object in the sky. More recently, it is used to describe clouds of gas in space. Some nebulae are illuminated by nearby stars (bright nebulae), while others remain dark and are only seen if they obscure a brighter object (dark nebulae).

| nebula |
A cloud of gas and/or dust in interstellar space. (The word nebula in Latin means "cloud"; its plural is "nebulae.'') Nebulae can make themselves apparent by glowing (as "emission nebulae''), by scattering light from stars within them (as "reflection nebulae''), or by blocking light from things behind them (as "obscuration nebulae'').
