ANN's Daily Aero-Term (04.09.09): Lenticular Galaxy

Aero-Terms!

Aero-Terms are designed to be a daily reminder of the terms, names, acronyms and explanations of the unique language that populates the aviation world. Aerospace, sport aviation, fixed wing, helo, you name it... it's all fair game.

Aero-Terms should serve as a quick but intriguing reminder of the terms you may use every day, or an introduction to an aspects of the Aero-World you may not yet be familiar with. ANN also encourages readers to go beyond the FMI link, and further research any intriguing terms.

Suggestions for future Aero-Terms are ALWAYS welcome, as are additions or discussion of the explanations given for each Aero-Term.

Lenticular Galaxy

A galaxy with a central bulge and disk but apparently lacking spiral arms and substantial amounts of interstellar material. Lenticular galaxies are so named because of their lens-like appearance when seen edge-on. In the Hubble scheme of galaxy classification, lenticulars are known as S0 galaxies and are intermediate in form between spiral galaxies and ellipticals.
