Astronomers have found a distant world that challenges planetary formation theory, with a rocky planet where gas giants should be.

"The Solar Family" is an 11-minute educational film produced by Encyclopedia Britannica Films in 1936. It presents the evolution of the solar system through the lens of the planetesimal hypothesis, a ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

Astronomers say a newly discovered solar system about 116 light years from Earth is challenging long held ideas about how planets form.According to CNN, researchers using telescopes from NASA ...

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 ...

Since the 1990s, scientists have discovered approximately 6,100 planets outside our solar system, called exoplanets.
