Before the sun fully formed, tiny bits of rock were already recording the magnetic forces present in the very early solar ...

Asteroids are leftover pieces from the formation of our solar system about 4.5 billion years ago. In the beginning, ...

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 ...

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 ...

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system’s first 200,000 years. The discovery suggests magnetism worked ...

If the outer solar system’s first solid bodies had come with a recipe, it would have called for a generous helping of chondrules, millimeter-sized beads of rock forged by heat, and very little icy ...

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 ...

Look up on a clear night and it's easy to blur the line between the two. both feel like distant, abstract terms for "space ...

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 ...

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 ...

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 — ...
