Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

Astronomers are increasingly finding planets that do not simply circle their stars in neat, clockwork ellipses but instead trace out paths that look more like intricate choreography. The latest ...

AMES, Iowa – Using data from NASA’s Kepler space telescope, an international team of astronomers has discovered a distant planetary system featuring multiple planets orbiting at a severe tilt to their ...

Over the next several nights in the Philadelphia region, through its peak on Friday, we will have the opportunity to see all seven of our sister planets simultaneously and in a straight line, parading ...

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 ...

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 ...

Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic exoplanet system TOI-201. They include a super-Earth (TOI-201 d), a warm Jupiter ...

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 ...
