Saturn’s iconic rings have remained one of the greatest wonders that amazes every skygazer observing the Universe. However, scientists have proposed several theories on how Saturn rings existed. A recent study suggests that a massive moon collision between two ancient icy moons that may have once traveled around Saturn could have given the planet its iconic rings.
Saturn is no stranger to housing moons, as astronomers have discovered that the most ringed planet in the solar system accommodates 145 known moons. Astronomers behind this study suggest that it occurred millions of years ago. This implies that the dinosaurs were around while the iconic rings were forming around the gas giant.
How astronomers conducted the new study about the moon collision forming iconic Saturn rings
Scientists used the data obtained by NASA’s Cassini mission, which traveled around the orbit of Saturn between 2004 and 2017, to conduct this study. The researchers studied dozens of computer simulations based on the obtained data to suggest that they may have discovered a more accurate answer to the origin of Saturn’s rings.
While conducting its 13-year mission around Saturn, the Cassini space probe discovered the unique materials that make up the ring. These materials include icy fragments that have remained unpolluted by space dust. Based on this discovery, scientists realized that the iconic rings of Saturn may be only a few million years old. This implies that the ring system was not formed alongside Saturn about 4.5 billion years ago.
What the Team Discovered about Saturn Rings
The team behind this study consists of researchers from NASA and Durham University in the U.K. They collaboratively suggest that the rings of Saturn may have been created from a recent collision of two ancient icy moons of the gas giant. They deployed the potential of sophisticated supercomputers to simulate about 200 different scenarios that could have caused the moon collision. The outcome of the study suggests that these two moons were as huge as Saturn’s current moons, Dione and Rhea.
Vincent Eke, Associate Professor in the Physics Department at Durham University, stated that they have tested a hypothesis for the latest information concerning Saturn’s rings. Based on their observation, they realized that a severe impact of icy moons in the Saturnian system could provide enough materials to form the beautiful rings of Saturn we see presently.
The rings around Saturn consist of ice. However, scientists still think that the planet’s icy moons that led to the existence of the rings have rocky cores.
What’s More?
The simulations analyzed during this study proved that the icy fragments and rocky pieces would surely spread around the gas giant in different ways after the huge collision.
This would possibly allow the rocks to come together and form new moons while the ice would move closer to orbit around Saturn. Generally, rings only form around celestial bodies that fall within the Roche limit. The simulations revealed that several of the hypothetical collisions would pump massive amounts of ice into lower altitudes while the rock would come together in higher orbits.
Eke also said that this particular scenario made scientists naturally think that Saturn’s rings are rich in ice as the rocky cores of the colliding moons are dispersed less widely than the overlying ice when the moons collided.
The researchers published their findings in The Astrophysical Journal on Sept. 27.
Conclusion
Scientists conducted a new study that revealig how the formation of Saturn’s rings became possible from the collision between two icy moons millions of years ago. Researchers will still have to conduct more studies to learn about this discovery. What do you think about Saturn’s rings created by moon collision?
