Currently, over 45,000 human-made objects are orbiting our planet, forming a tangle of trajectories that seems increasingly difficult to secure. A team from the Lawrence Livermore National Laboratory ...

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 ...

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

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...
