This is a still from a simulation of a forming planetary disk, made by University of Warwick and Stephen Hawking Research Fellow Rebecca Nealon. The images show the rotating inner disk along the top ...

Hubble observations reveal a giant, turbulent planet-forming disk that may reshape theories of how planetary systems develop.

Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet surveys suggest that just four layouts may dominate the universe. Drawing on ...

Simulation of the disk in the 2MASS1612 system. The planet is seen as a bright dot in the simulation that circles the central star within the gap of the disk. The planet drives the spiral arms seen in ...

New simulations offer new explanation for star's 85-year flare. In this scenario, a young giant planet is burning up very close to its star, suggesting solar systems may have hosted many of such ...

Long before Mercury, Venus, Earth, and Mars formed, it seems that the inner solar system may have harbored a number of super-Earths–planets larger than Earth but smaller than Neptune. If so, those ...

Although Pluto lost its status as “Planet Nine” when it was downgraded to dwarf planet, there is ample evidence that our solar system either had or currently has a large planet far beyond Pluto that ...
