If you examine our solar system’s giant planets, you’ll notice right away that they’ve all got moons—a lot of moons. While ...

Although astronomers have found thousands of exoplanets, the number of confirmed exomoons—and exorings—is still zero. But ...

Grillmair persevered, however, and soon made the “monumental” discovery of detecting signs of water on another planet, IPAC ...

A team of U.S. and U.K. researchers has outlined a new way to detectalien moons by tracking subtle flashes of reflected light during lunar eclipses in distant planetary systems. The method, designed ...

Our solar system hosts almost 900 known moons; more than 400 orbit the eight planets while the remaining orbit dwarf planets, ...

Computer simulations suggest NASA’s Habitable Worlds Observatory could detect Earth-like exomoons around gas giant exoplanets through reflected starlight and lunar eclipses.

Far beyond our solar system, in the distant Pegasus constellation, lies a star system that is reshaping our understanding of planetary formation. HR 8799, located 129 light-years away, is home to a ...

In this artist’s concept, exoplanet candidate HD 137010 b orbits a Sun-like star about 146 light-years away. Credit: NASA/JPL-Caltech/Keith Miller (Caltech/IPAC) One way scientists search for ...

Magnetic fields play a crucial role in shaping planetary environments, protecting atmospheres, and influencing habitability, yet they remain largely unobserved in exoplanets. In this talk, I will ...
