Before Earth and the other planets in our Solar System existed, the Sun may have been surrounded by giant rings of dust similar to Saturn's, according to a new study.
Their simulations suggested that pressure"bumps," or high-pressure regions of gas and dust, would have surrounded the infant Sun. These areas of high pressure likely resulted when particles moved toward the Sun under its strong gravitational pull, heated up, and released large amounts of vaporized gas.
"The effect of the pressure bump is that it collects dust particles, and that's why we see rings," co-author Andrea Isella, an associate professor of physics and astronomy at Rice University, said in the statement.
