The term Planetary Nebula is one type of Nebulae (Not nebulas), which are large clouds of ice and dust that have been created in the aftermath of the death of a star. Although their name includes “planet”, they are nothing to do with planets. They do get their name from the mistaken...
A planetary nebula is a phenomenon that occurs when a small to medium-sized star approaches the end of its life cycle. While very large stars end their lives in an explosion of light called asupernova, smaller stars fade out more gradually as gases and radiation exit their core. The first...

The planetary nebula is a glowing record of the final death throes of the star. (Optical images are courtesy of the Magellanic Cloud Emission Line Survey (MCELS) team). Associate Professor Miroslav Filipović from the University of Western Sydney and his team argue that the detections of ...
What is planetary habitability? Habitat: Habitat is the natural place where an organism lives and grows in the natural environment. The habitat of organisms supports the survival and reproduction of certain species. Answer and Explanation: Learn more about this topic: ...
A planetary nebula is formed at the end of the life of a star which has a mass about equal to that of our Sun. Any much more massive star cannot pass through this relatively gentle stage; it explodes in a shattering super-nova. A star much less massive than the Sun simply fades out...
After graduation, Martin took a job guiding visitors at the Adler Planetarium. She’s since been promoted to run live shows for visitors, pointing out constellations, planets, and formations in the sky. One of those formations is the planetary nebula Martin wrote about for he...

The Orion Nebula is a perfect example of a star-forming region or “stellar nursery”. Planetary Nebulae When early astronomers observed these round, compact nebulae in the night sky – they thought that they must be planets. In reality, planetary nebulae have nothing to do with planets. ...
