An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how ...

Gas giants are massive worlds made mostly of hydrogen and helium. They lack solid surfaces, and in our solar system, Jupiter ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

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

For the first time, astronomers have successfully observed a planet in the midst of its formation, a groundbreaking achievement that provides invaluable insights into the processes that shape ...

Analysis of an ancient meteorite suggests that rocky planets both near and distant from the sun may have formed at the same ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Gas giants are large planets mostly composed of helium and/or hydrogen. Although these planets have dense cores, they don't ...

Dr. Jane Huang's research on planet formation in harsh environments, particularly within the Sigma Orionis cluster, offers surprising insights into the universality of planet formation. In a recent ...

Scientists have identified a rocky outer planet in a system where a gas giant was expected. The discovery challenges ...

Gas giants possibly developed slowly in the solar system. They developed cores layer by layer within a disk of ice and dust ...

Hit-and-run collisions between embryonic planets during a critical period in the early history of the Solar System may account for some previously unexplained properties of planets, asteroids, and ...
