Planets without stars to orbit raise important questions about how planets evolve and what habitability might look like ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

Forbes contributors publish independent expert analyses and insights. Leslie Katz covers the intersection of culture, science and tech. A yellowish-orange glow bathes Phainoterra, a planet of dramatic ...

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 ...

By combining models of high-energy astrophysics with planetary science, I study how violent astrophysical events influence the formation and evolution of planetary systems. I am particularly ...

I’m a planetary scientist who was born the year of Sputnik’s launch. Over the course of my 40-year career, I’ve witnessed not one but at least five separate revolutions that fundamentally transformed ...

Scientists have identified three Earth-sized planets orbiting two stars in the TOI-2267 system. Remarkably, planets transit around both stars — a first in astronomy. The system’s compact, cold nature ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...
