Estimated Reading Time: 10 mins
Published: Feb 19, 2019
1. Not At All. Unfortunately, it is entirely possible that we are the only planet in the universe that has life. Due to the vastness of space and the limit that light speed imposes on intergalactic travel, it may be impossible for us to ever discover other life or even determine if it exists at all.
2. Panspermia. A popular theory is that life propagates through the universe through planetary ejection caused by large impacts on previously populated planets.
3. Celestial Life. Although science does not currently suggest that stars or galaxies themselves could form life, it does indicate that life with organic compounds can form outside of a home planet with the help of nearby stars and star structures.
4. Plasma-Based Life. This one truly falls into the realm of science fiction. By modeling conditions that are possible in space, a 2007 study found that plasma and dust can function in a way that may qualify as life.
5. Hybrid Life. If creatures could hypothetically evolve using an entirely different basis for life than that on Earth, why couldn’t they combine multiple methods?
6. Carbon-Based Life. Carbon-based life-forms are the only type which we, being carbon-based ourselves, know anything about. Thus, we’re sure that hundreds of planets exist within the potentially habitable zones of their stars.
7. Methane-Based Life. There are some environments in which methane would be far more prevalent than water. Saturn’s moon Titan is a prominent example. According to a computer model, life which relies on methane would be able to exist in extremely cold areas as well as regions entirely without oxygen.
8. Ammonia-Based Life. Water is an essential part of all Earth life. Our bodies use the liquid as a solvent, which is necessary for almost all chemical reactions that create energy and sustain functions.
9. Arsenic-Based Life. Although it seems counterintuitive that one of the most iconic poisons on Earth has a basis in forming life, science suggests that it is entirely possible for arsenic to be incorporated into complex biomolecules.
10. Silicon-Based Life. Silicon is a molecule whose structure and chemical properties are remarkably similar to the properties of carbon—the element on which most life on Earth is based.

Frequently Asked Questions

Are there any life forms in space?

While these experiments have yet to provide a definitive answer, they are generating data telling us more about the probability of other forms of life being out there. Most space scientists agree it is unlikely life has only occurred in our little corner of the universe.

Are there any life forms on other galaxies?

However, the most favorable galaxies for life are probably those like the Milky Way—big, bright spiral galaxies. The Andromeda Galaxy is the only other galaxy within our Local Group that is similar to the Milky Way—basically, the Local Group consists of the Milky Way and Andromeda plus a bunch of small "satellite galaxies" of each.

Does life exist in other galaxies?

Life probably does exist in other galaxies. In science, there is no real uniqueness to something. In fact if the universe prefers something over something else (in this case our galaxies vs the other billions of galaxies) it would be mind boggling like the oddity of particle spins.

Is there life in the outer space?

Is there life in outer space? Most people have wondered if there is life beyond Earth in space. With all of the countless billions of stars and possible planets and moons in space, many people think that under the right conditions, life can exist elsewhere in space. However, there is no evidence for this yet.
