Do you know which planet could float in a giant bathtub? Discover the science behind its low density, its hundreds of moons, ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one young star should help us understand how such systems form ...

Compared to our 4.5-billion-year-old sun, ​​the 20-million-year-old V1298 Tau is a stellar baby, making it ideal for ...

Thomas White is an associate professor in the Department of Physics, and he’s interested in learning about what’s on the inside of planets and the states of matter it exists in. “The easiest question ...

Astronomers have discovered a gas giant planet with the density of a marshmallow orbiting a cool red dwarf star located 580 light-years from Earth. The Jupiter-like exoplanet is the lowest-density ...

Two tightly packed families of exoplanets are pushing the boundaries of what a planetary system can look like. New studies of the makeup of worlds orbiting two different stars show a wide range of ...

Astronomers have discovered a new Jupiter-sized exoplanet that possesses less than one-third of the mass of the solar system's largest planet, giving it a density similar to a marshmallow. The team ...
