Summary (IA Generated)

Astronomers from the University of Copenhagen recently published an incredible study demonstrating there’s a high likelihood the Milky Way is absolutely flooded with potentially life-bearing planets.

Published in Science Advances, the team’s paper entitled “A pebble accretion model for the formation of the terrestrial planets in the Solar System,” lays out and attempts to validate a theory that planets are formed by tiny, millimeter-sized pebbles massing together over time.

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 and project we’ll find the same scenario in most other exoplanets.

Per a university press release, lead 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.

It’s looking less and less like we’re alone in the universe and more and more like we could discover some form of life on other planets within a matter of decades.
