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 ...

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.

Scientists were able to see the moment when planets began to form around a star. Astronomers have witnessed the birth of a solar system beyond our own for the first time. An international team of ...

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 ...

About 4. 6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity.

Scientists have shown that Earth’s basic chemistry solidified within just three million years of the Solar System’s formation. Initially, the planet was barren and inhospitable, missing water and ...

The birth of a new solar system may have been caught on camera. About 1,400 light-years from Earth sits a young sunlike star surrounded by cooling gas and teensy silicate minerals. These mineral ...
