There are many unique ways that life could be created or sustained in the universe. Even within our own solar system, there are objects that may have had life before or still do, although it’s unlikely. Take for example, Titan, one of Saturn’s moons.

This moon is very similar to Earth in some ways. There is rain, clouds, and even seasons on this moon. The problem is that Titan is currently at a distance from the sun that makes it so cold that it seems impossible to sustain life. But over time, the sun will heat up causing Titan to be in the GHZ (Galactic Habitable Zone). This is where it is cold enough that water won’t evaporate and warm enough where water won’t freeze. This could mean that eventually life may form or humans could make it their home because sadly, Earth won’t be a planet for forever. This goes to show that new, habitable, planetary bodies are constantly being created, only increasing the chance of there being life out there.

Outside of our solar system, about 2,000 light years away, a very unique star resides. Epsilon Aurigae is unique because comets and asteroids are always colliding, creating planets. It is believed that some of these comets and asteroids carry organic materials that were used to create life on Earth. If so, there would be a good chance that life exists on one of the planets orbiting this star. The same conditions that started life on Earth could easily happen again within this solar system.
