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 ...

Are planets in the solar system that are closer to the Sun older than the ones further away? – Gavriel, age 10, Paducah, Kentucky A cloud of collapsing gas created our Sun, the first thing to form in ...

Asteroids, the enduring remnants of early Solar System formation, offer invaluable insights into the processes that shaped planetary evolution. Their diverse orbits, sizes and compositions not only ...

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 ...

The period of orbital instability that led to the migration of the Solar System’s giant planets to their current orbit occurred between 60 and 100 million years after the beginning of Solar System ...

The film discusses the formation of the solar system, originating from a vast cloud of gas and dust over 4.5 billion years ago. It highlights the role of comets, which may contain remnants of the ...

To better understand why the planets have variable compositions, we have to first understand the process of how stars form. While the composition of gas and dust in a precursor molecular cloud is ...
