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 ...

Active small bodies—including comets, active asteroids, icy minor planets, and transitional objects—occupy a unique position in planetary science. As ...

A group of astronomers has found a solar system 116 light-years from Earth that seems to challenge current theories about how ...

Planetary systems such as our solar system take hundreds of millions of years to evolve. Since humanity has only existed for a sliver of that time, astronomers have only observed planetary systems at ...

Stellar astronomy and planetary systems form a cornerstone of astrophysical research, uniting our understanding of the life cycles of stars with the intricate architecture of the systems that form ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous neighbors, possibly after much of the ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

Astronomers have discovered seeds of rocky planets forming in the gas around the baby sunlike star providing *** peek into the start of our own solar system. The the thing that we've discovered is ...

"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 ...
