In this map of overlapping orbital resonances, the regions between resonances are colored black and could allow for stable satellite orbits under optimal conditions. The light green curve connects ...

Astrophysicists have once again enriched our knowledge of the cosmos with a new discovery: two small planets orbiting ...

This complex but predictable pattern, called an orbital resonance, occurs when planets exert a regular, periodic gravitational tug on each other as they orbit their star. What the data showed ...

Throughout its history, NASA has produced striking images, from the iconic Earthrise to the breathtaking images of the Pillars of Creation, first captured by the Hubble Space Telescope and later by ...
