2008-04-07 · A planetary nebula is an astronomical object consisting of a glowing shell of gas and plasma formed by certain types of stars at the end of their lives. The name originates from a similarity in appearance to giant planets when viewed through a small optical telescope, and is unrelated to planets of the solar system. A nebula is a cloud of gas and dust in space. Some nebulae (more than one nebula) are regions where new stars are being formed, while others are the remains of dead or dying stars.

Some nebulae are born from the explosion of a dying star; others are regions of According to this theory, the sun, the planets, and all the celestial objects in the solar system evolved from a cloud of dust and gas called a nebula. The nebula When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

They do not last for long compared to a star, only tens of thousands of years. Planetary nebula definition, an expanding shell of thin ionized gas that is ejected from and surrounds a hot, dying star of about the same mass as the sun; the gas absorbs ultraviolet radiation from the central star and reemits it as visible light by the process of fluorescence. Planetary nebulae are the cloudy remnants of smaller stars that have shed their outer layers of gas, but haven't exploded into supernovas. The following is an incomplete list of known planetary nebulae. Image Name Messier Catalogue NGC Other designation Date discovered Distance Apparent magnitude The planetary nebula has only a short life compared to the time scales in stellar evolution, being visible only a few thousands or 10,000s of years, and then fading out as its matter is spread in the cosmic environment, enriching the interstellar matter with carbon, oxygen, and other elements.
