The Southwest Research Institute (SwRI) has launched a new laboratory to investigate the chemical origins of planetary systems. The Nebular Origins of the Universe Research Laboratory aims to connect pre-planetary evolution to planetary formation, filling key data gaps in understanding the solar system's early history.
Scientists analyzed particles from asteroid Ryugu, revealing a weak magnetic field that likely pulled matter inward to form the outer planetary bodies. The team estimates that such a low-grade field intensity would have been enough to play a role in giant planet formation, from Jupiter to Neptune.
A new SwRI study posits that the large mounds on Kuiper Belt object Arrokoth are similar in size and shape, suggesting a common origin. This finding supports the streaming instability model of planetesimal formation, where gentle collision speeds allowed objects to accumulate and form Arrokoth.
Researchers found tiny salt crystals in an asteroid sample, indicating the presence of liquid water. The discovery challenges previous assumptions that ordinary chondrite asteroids lack hydrated minerals.
Researchers using Hubble Space Telescope spot large dust particles in rings around three stars, suggesting planets may be forming. The observations reveal a critical early stage in planetary evolution, with the potential for millions of years of dust grain aggregation to form planets.
Researchers measured the velocity of gases ejected during an early phase of supernova formation, allowing them to tie its formation to the star's evolutionary phases. The study found that the entire nebula is at least 200,000 years old and probably several times older.
