Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...
As our solar system formed, tiny particles in the disk around the young Sun gradually grew larger until they became the size of small pebbles. "Once pebbles grow large enough to no longer travel along ...
A new study suggests yet another theory for a possible extra planet in our solar system, likely of a size between Mercury and ...
The asteroid belt may seem permanent, but it is far from static. Its slow decline reveals a more violent past when more ...

Outside our own solar system, the first moments of planet formation have never been detected, until now. The European Southern Observatory (ESO) said the images are of a "baby star" known as HOPS-315 ...
The timing of Earth's early formation points to a planet that started out dry. So, life’s essential building blocks arrived ...
The asteroid belt is found orbiting between Mars and Jupiter and is a vast collection of rocks that is thought to be a planet ...
The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...
The JWST has studied the chemical composition of a moon-forming disk circling a giant planet 625 light-years away.
