A newly analyzed planetary system spotted by NASA’s TESS mission is challenging long-standing assumptions about how planets ...

NASA’s TESS mission has revealed TOI-201, a planetary system with three very different worlds on tilted, gravitationally interacting orbits — a stark contrast to the orderly layouts seen in most ...

Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic ...

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, ...

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the ...

Retrograde mean motion resonances occur when orbiting bodies, moving in directions opposite to the dominant sense of motion, experience periodic gravitational interactions that can stabilise their ...

An artist's impression of a planetary system with four planets, around a small red star, called LHS1903 with a large reddish-brown rocky planet with craters is visible in the foreground and three ...

WASHINGTON – 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 ...
