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
Planetary nebula: The Helix Nebula This is composed of expanding gas that was blown off by a star as it collapsed to a white dwarf. (Image credit: NASA, ESA, J. Hester, A. Loll (ASU)) Supernova remnant: The Crab Nebula Exactly as the name says, this is all that remains of a ...
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...

This month’s elongation happens within only 5 hours of Mercury reaching perihelion at 46 million kilometers from the Sun. This means that Mercury won’t peak above the dusk horizon for mid-northern latitude observers quite as high as it will during the next evening apparition of the planet ...
big enough. It would need to be about ten times more massive to collapse with such force.The life cycle of a stardepends on its size, and the ultimate fate of a star the same mass as our sun is to essentially burn out. Before that happens, though, the heat is going to go way up...

during which time planet Earth and the entire Solar System was born, it has remained relatively unchanged. This will stay the case for another four billion years, at which point, it will have exhausted its supply of hydrogen fuel. When that happens, some pretty drastic things will take place...
Erik Kuna, has been enthralled by the nebula since he first captured a nebula shot during the CRS-17 launch last year. According to Kuna, most launches can cause stunning light shows, it's just not always as pronounced. "It happens every launch, just some are more prominent than others...
has a different fate from stars with higher masses. It will blow off its outer layers, creating a planetary nebula with a white dwarf in the middle. Astronomers have studied many other stars that have undergone this process, which gives them greater insight into how the Sun will end its lif...
