While some scientists struggle to find life on exoplanets, some have already found a new viable location for alien life: exomoons.
Exomoons are satellites that orbit planets which are outside our solar system and may be found around the Milky Way. If would be fascinating if we could find such examples in the solar system but the chances seem to be slim according to one source.
In our own solar system, 185 moons orbit 6 of the eight planets, with a number of more than twenty to one for each planet. Take into consideration that billions of planets may exist in the universe and the number of possible exomoons is exponentially bigger as trillions of exomoons may exist. This may sound a bit outlandish nut it is a reasonable theory since most moons appear after the formation of the original planets.
We should also keep in mind that while we use our solar system as the default template, there may be thousands of different solar systems in the universe, each with its own particularities.
Should we do bit of math suppose that there are 200 billion planets in the universe and the 20-1 ratio is viable, it would mean that four trillion exomoons exist out there.
This dramatically increases the number of places that may potentially host life forms since habitable moons may, in fact, be real. One of them, Jupiter’s moon Europa has been proven to have an underground salted sea, and Enceladus, a Saturn moon, has one too.
The satellites for form a feasible archetype, namely a large moon with liquid water reserves that orbits a large planet and it may be the best track we have for now.
Of course, there are certain conditions to be met, such as the proper size that would allow the existence of an atmosphere. A moon that is the size of Earth orbiting Jupiter would seem the safest bet for no.
It remains to be seen if such a moon will be found but for now it looks promising.
Laura grew up in a small town in northern Quebec. She studied chemistry in college, graduated, and married her husband one month later. They were then blessed with two baby boys within the first four years of marriage. Having babies gave their family a desire to return to the old paths – to nourish their family with traditional, homegrown foods; rid their home of toxic chemicals and petroleum products; and give their boys a chance to know a simple, sustainable way of life. They are currently building a homestead from scratch on two little acres in central Texas. There’s a lot to be done to become somewhat self-sufficient, but they are debt-free and get to spend their days living this simple, good life together with their five young children. Laura is an advocate for people with disabilities.
