This gas forms a beautiful cloud around the star called a Planetary Nebula(行星状星云) . When will the Sun expand into a giant, and then shrinkleaving behind a planetary nebula? Don't worry. The sun is only about 5 billion years old. It stillhas another 5 billion years before it will...
creating a planetary nebula. This nebula can take many different forms depending on the type of gases it contains and the life stage of the star. Some feature a solid disk shapes that resembles a planet, while others
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...
“Even though the interstellar gas is very dispersed, the amount of matter adds up over the vast distances between the stars. Eventually, along with enough gravitational attraction between clouds, this matter can combine and collapse to forms stars and planetary systems.” ...

Not all stars end their days in the relative serenity of a planetary nebula. A star that’s much more massive than the sun will eventually explode as a supernova, and the debris flung out from that explosion forms yet another kind of nebula called a supernova remnant. The most famous of...
Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon- to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found. Ureilites are one of the main families of achondritic meteorite...
However, we did detect one interesting object: an OH 1612 MHz maser in the young planetary nebula NGC 6302. This nebula may be in a brief evolutionary stage, similar to the young and compact planetary nebula Vy 2-2 where OH has already been detected....
