The boundary between stars and planets appears increasingly indistinct. Objects such as brown dwarfs, neither fully stars nor fully gas giant planets, blur the well-established categories defined by ...

When a star is born, it doesn’t emerge in isolation. Instead, it forms inside a large, chaotic cloud of gas and dust. Around it, a flat disk of spinning material takes shape. This protoplanetary disk ...

Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many ...

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain ...

The combination of theoretical models and empirical data provides a new perspective for understanding the complex interactions between young stars and their environments. A study led by Paolo Padoan, ...

Zooming in on 78 disks in the Ophiuchus star-forming region, scientists saw hitherto undiscovered structures around young stars. When you purchase through links on our site, we may earn an affiliate ...

Researchers at UC Santa Barbara, The University of Texas at Austin, Yale University and National Taiwan Normal University have found that a fair number of sun-like stars emerge with their rotational ...

Astronomers are just beginning to scratch the surface of the complex, and sometimes violent, relationships between planets and their parent stars. When you purchase through links on our site, we may ...

While a planet can orbit around a Sun-like star and sit comfortably within its habitable zone, it could also potentially not ...

Astronomers identify 27 possible circumbinary planets orbiting two stars, expanding the search for worlds beyond our solar system.
