Water Ice Discovered on Asteroid for First Time figure 6 is indeed gapped, with a long space between the halo area close to the manufacturing.20 in the journal Science Advances (opens in new tab). As these bodies moved inward, toward the sun, this ice started to melt, leaving the ice fossils in its place, he said. Astronomers confirm star wreck as source of extreme cosmic particles. Using a model that simulated how Acfer 094 grew and how the planets in the solar system formed, the researchers determined that fluffy ice and dust particles came together in bigger bodies beyond the snow line - the distance from the sun where it's cold enough for solid ice grains to form - and then migrated toward the sun, Epifanio Vaccaro, curator of petrology at the Natural History Museum in London and co-author of the study, said in a statement (opens in new tab). The discovery of the asteroid ice fossils reveals how primordial ice was "brought into and distributed to the meteorite parent body," Matsumoto said. However, until now, it has remained a mystery how this ice got there, Matsumoto said. Researchers have previously identified (opens in new tab)interactions between water and rocks that happened when ice melted in the larger objects that broke off into objects like Acfer 094. ![]() These findings allow researchers to look back in time at the material that eventually formed objects like asteroids and the planets in our solar system (opens in new tab), and the study vastly improves scientists' understanding of how those materials came to form those objects. As they grew, they heated up, and that early-solar-system material they started with started to melt and recrystallize, the study authors explained. And some of these small, newly formed protoplanets contained ice. In the early solar system (opens in new tab), swirling dust, gas and sometimes ice compacted and formed objects like rocky asteroids or even larger protoplanets (astronomical objects about the same size of the moon that are formed when planetesimals, or small solid astronomical objects, combine). So, by finding the pores, they discovered evidence of this ancient ice. The pores in this material were likely created when ice that previously filled the space disappeared, the team found.
