A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

Constraining the timing of accretion, differentiation, and breakup of early-formed protoplanets helps to unravel the Solar System’s evolution. The recent discovery of the oldest crustal material, Erg ...

Accretion processes in protoplanetary disks produce a diversity of small bodies. In our solar system, small bodies played a crucial role in both early and late accretion of planets, after potentially ...

Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published ...

New work from Carnegie’s Alan Boss and Sandra Keiser provides surprising new details about the trigger that may have started the earliest phases of planet formation in our solar system. It is ...

It's an exciting time for the fields of astronomy, astrophysics, and cosmology. Thanks to cutting-edge observatories, instruments, and new techniques, scientists are getting closer to experimentally ...

Jupiter, Saturn, Uranus and Neptune did not always have their current positions in the solar system. According to the planetary-instability model, they were born a little closer to the Sun and closer ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...
