While scientists have made many impressive discoveries about the universe over the years, they have yet to agree on a single model that explains how the solar system formed. The prevailing theory is that a massive star exploded billions of years ago and compressed a dense cloud of interstellar dust and gas until it collapsed under the force of gravity to form new stars — including our sun.
But scientists at the University of Chicago and Clemson University have proposed an alternative theory that suggests the solar system instead formed within the walls of a massive bubble surrounding a Wolf-Rayet star. Read more. See the study here.
