The outer reaches of our Solar System continue to reveal a complex dynamical environment where the interplay of gravitational forces shapes the orbits of a myriad of distant bodies. Research in this ...

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula — a key stage during which much of the solar system evolution took shape. This new estimate suggests that the ...

TOI-1136, a dwarf star located more than 270 light years from Earth, is host to six confirmed exoplanets and a seventh as yet unconfirmed candidate. The system has provided a rich source of ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." When you purchase through links on our site, we may earn ...

A new analysis estimates that the asteroid belt is steadily losing mass each year, and may not be as permanent a feature of the solar system as we thought. When you purchase through links on our site, ...

The Antarctic Meteorite Collection at the National Institute of Polar Research (NIPR) in Japan has been recognized as a Geo-collection by the International Union of Geological Sciences (IUGS). An IUGS ...
