A rocky planet beyond gas dwarfs in LHS 1903 indicates that planetary systems form in unexpected ways.

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, ...

Astronomers say they have discovered a distant planetary system with planets arranged in a surprising order, challenging long-standing ideas about how planets form. In our Solar System, the four ...

Discover how a rare "kiss and capture" impact gave rise to the Pluto-Charon binary system, shedding new light on the evolution and motion of icy worlds in the outer solar system. (CREDIT: NASA) ...

A research team led by University of Minnesota School of Physics and Astronomy Professor Yong-Zhong Qian uses new models and evidence from meteorites to show that a low-mass supernova triggered the ...

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 ...

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 ...
