Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...

For decades, the solar system set the template: small rocky planets close to the star, gas giants farther out, beyond a boundary called the snow line where icy grains help cores grow fast enough to ...

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a ...

More than one-third of the giant planet systems recently detected outside our solar system may harbor Earth- like planets covered in deep global oceans that offer abundant potential for life, ...

An unusual planetary system with three known ultra-low density 'super-puff' planets has at least one more planet, according to new observations. An unusual planetary system with three known ultra-low ...

Chondrite meteorite origin upended by July 2026 Science Advances study: SwRI researchers show the most common meteorites ...

Looking ahead: Future searches using data from TESS and Gaia could target the lower-density edges of stellar streams to locate intact planetary systems. The work explores how a star’s birthplace ...

Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain life-supporting atmospheres, focusing on size and atmospheric dynamics. Subscribe to ...
