Astronomers from the University of Copenhagen recently published a shocking study that suggests there is a very high possibility there is other life in our galaxy.
Published in Science Advances, the paper, titled “A pebble accretion model for the formation of the terrestrial planets in the Solar System,” attempts to confirm a theory that planets are formed by tiny, millimeter-sized pebbles massing together over time.
According to the researchers:
We show that a pebble accretion scenario for terrestrial planet formation provides explanations for several properties of the terrestrial planets in the Solar System, including the masses and orbits of Venus, Earth, and Mars, the isotopic composition of Earth and Mars, and the delivery of carbon and water to Earth in amounts that are comparable to the inferred reservoirs.
The scientists believe Earth, Mars, and Venus were formed this way. They predict we will find the same scenario in most other exoplanets, which means it’s possible that most planetary bodies have some form of water on them.
In a university press release, researcher Anders Johansen says carbon-based life may be a much more frequent occurrence than once thought:
All planets in the Milky Way may be formed by the same building blocks, meaning that planets with the same amount of water and carbon as Earth – and thus potential places where life may be present – occur frequently around other stars in our galaxy, provided the temperature is right.
This is one of the biggest breakthroughs indicating that there are other planets like Earth closer than we thought. Perhaps we even have neighbors in our own galaxy.
