New work offers fresh evidence supporting the supernova shock wave theory of our solar system’s origin. According to one longstanding theory, our Solar System’s formation was triggered by a shock wave ...

Billions of years ago, in the frozen edges of the solar system, a violent impact shaped one of space’s oddest pairs. Instead of a typical planet-moon setup, Pluto and Charon became a binary system.

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 ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Jupiter is the largest planet in our solar system (so large, in fact, that some scientists think it might have even consumed other worlds), a gas giant so massive that it shaped the orbits and ...

Rosetta's trip to a comet might make scientists second guess the idea that magnetic fields led to the formation of planets. Share on Facebook (opens in a new window) Share on X (opens in a new window) ...

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our Sun. Like many small stars, it is not expected to provide suitable conditions for the formation and ...

Billions of years ago, Jupiter’s violent growth transformed the young solar system, smashing icy and rocky bodies together at incredible speeds. These cataclysmic collisions created tiny molten ...
