Ancient iron meteorites reveal that some of the Solar System’s first solid bodies were built mostly from tiny heat-forged rock beads called chondrules, while water-rich dust was largely excluded. The ...

What processes are responsible for the first planets in our solar system forming? This is what a recent study published in Nature Astronomy hopes to addres | Space ...

When most of us learn about the solar system, it seems like a pretty well-ordered place. Our sun formed first, about five billion years ago, and the planets appeared a little later. As a very general ...

During the Solar System’s first million years, its earliest outer worlds appear to have formed from a carefully filtered mix ...

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 ...

Everything we know about the formation of solar systems might be wrong, says University of Florida astronomy professor Jian Ge and his postdoc, Bo Ma. They’ve discovered the first “binary-binary” – ...

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 ...

A new study published in The Astrophysical Journal has traced six chemically distinct families of the Solar System's oldest meteorites to a single ring-shaped dust trap just beyond Jupiter's orbit — ...

The smallest planet in the Solar System may have shrunk more than previously thought over the course of its history. Scientists now estimate that Mercury may have lost up to 23 kilometers in diameter ...

Before Earth existed — before the Sun ignited — ancient stars lived out their full lives, forged their elements, and died. A study published July 29 in Science Advances now shows that some of their ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...
