In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars—sometimes thousands of astronomical ...
This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton’s ...
The Sun makes Earth habitable, governs its climate and drives a variety of natural phenomena through its variable magnetism. Indeed, all planets in and outside the Solar System exist under the ...
Sixty-six light-years away, an Earth-sized exoplanet completes an orbit in under six hours, skimming around its star at nearly one-hundredth the distance that Mercury orbits the Sun. This planet is on ...
