Researchers used a pair of powerful supercomputers to simulate the potential trajectories of 1 million satellites in a ...

Could we prevent in-orbit crashes in the future by using advanced computer models?

On Feb. 20, 1962, Mercury-Atlas 6 mission launched, sending the Friendship 7 capsule containing John Glenn into orbit. Two ...

Lawrence Livermore National Laboratory creates a cislunar orbit map to help predict satellite stability and improve collision avoidance in increasingly crowded Earth orbits.

The coincidence of trends in abundance, metallicity and eccentricity points to two distinct pathways for forming small and large planets. "To see a transition in the eccentricities of the orbits at ...

Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that ...

For the inner four planets in this solar system, each planet orbits the sun three times for every two orbits of the planet immediately to its outside. For the fourth, fifth and sixth planets, they ...

The idea of waging war in orbit is no longer a figment of science fiction. As satellite technologies and launch capabilities ...

Astronomers Brown and Batygin have presented accumulating evidence supporting the existence of Planet Nine, a hypothesized planet in our solar system, based on the unusual orbital characteristics of ...

EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...
