An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

Astronomers have long believed that planetary systems follow a familiar blueprint. Small rocky planets ...

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 ...

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

The long-standing idea of planets forming in perfectly flat, orderly discs has been challenged by new research. Instead of calm, pancake-shaped structures of dust and gas, astronomers have now ...

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 ...

New research using NASA’s James Webb Space Telescope examines the maximum sizes of gas giant exoplanets, measuring chemical compositions and formation processes in the HR 8799 system.

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

Even under intense ultraviolet radiation from giant stars, the raw ingredients for planets can endure. Using Webb s powerful infrared eyes, astronomers examined a young star in the Lobster Nebula and ...

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 ...

For life to develop on a planet, certain chemical elements are needed in sufficient quantities. Phosphorus and nitrogen are essential. Phosphorus is vital for the formation of DNA and RNA, which store ...
