Planetary Nebula take on beautiful shapes and colors. There’s one called the God’s Eye Nebula because it looks like an eye. Similarly, M27 the Dumbbell Nebula, is classified as a Planetary Nebula which by the way is misleading. Contrary to what it’s name suggests, it’s not the creation of planets but the death of a Sun like star and its entire system. Something like this is what our solar system will look like in the distant future. Exciting isn’t it!
Planetary Nebula: Red Giant Phase
In approximately 4.5 Billion years, our Sun will exhaust the last of it’s hydrogen fuel in its core. At that point the core is not producing enough heat to balance the gravitation pull in the core which cause the core to contract (get smaller). The outer shell of the Sun, which is mostly hydrogen, will continue to burn and expand approximately beyond the orbit of Earth. Yes this will be the fiery death of our planet (if we don’t do it sooner). At this point the Sun will become a Red Giant. And humanity has 4.5 Billion years to actually become the, Star Trek/Star Wars, space traveling version of humanity needed to survive.
Planetary Nebula: White Dwarf Phase
As a Red Giant, the Sun’s core is fusing Helium to Carbon. When this fuel runs out, the core collapses again and more forceful. This creates a White Dwarf Star and expels the outer layers into space. As the outer material expands further it creates a beautiful structure called a Planetary Nebula. You can see the white dwarf star in the center of the nebula. Humanity surviving all this is dependent on our ability to travel from star to star.
The Andromeda Effect
So at the same time our solar system will be undergoing this change, our galaxy, the Milky Way, will be in the process of merging with our nearest galaxy neighbor, the Andromeda Galaxy. Isn’t timing everything. If humanity survives to that point just imagine the sights (off planet of course). It’s also possible during this merger that our solar system will be ejected from the Milky Way. So much chaos at one time. Should be fun! What will humanity be like or able to do by this time is crazy to think about.
How M27 Was Named
Designated M27 because it’s the 27th object catalogued by Charles Messier in 1764. It’s also called the Dumbbell Nebula or Apple Core Nebula because of it’s distinct shape. It is located in the constellation Vulpecula about 1227 light years away. This nebula is also between 10,000 to 15,000 years old.
