A new study challenges traditional models of how planets form. A new analysis of existing data suggests that exoplanets with masses comparable to Jupiter may have formed significantly earlier than ...

Using the now-retired Kepler space telescope, astronomers have discovered that larger planets grow up in more turbulent homes ...

All planets are made of gas, ice, rock and metal, and models of how planets form usually assume that these materials don't ...

What if water and hydrogen don’t stay separated inside planets like Earth and Neptune? New research from UCLA and Princeton ...

Researchers can see celestial snapshots with the James Webb Space Telescope, the most powerful ever launched, of the star ...

Even more exciting, the model suggests that some Earth-like planets could form in the habitable zone—the region around a star ...

This illustration shows a lower mass star surrounded by its planet-forming disk of gas and dust. The planet formation process would cause gaps, not shown in this illustration, to appear in the disk.

The smallest disk identified, meanwhile, stretched to just 0.6 AU – closer to the star than the Earth is to the Sun.

The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and ...
