Planet-disk interaction numerical simulation. The planet excites spiral waves in the disk and later opens gaps. The leftmost panel is the gas distribution in the simulation. The middle two panels show ...

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 ...

Astronomers have unveiled the largest planet-forming disk ever observed around a young star, a sprawling structure where gas and dust are actively assembling new worlds. The discovery pushes the ...

A young, massive planet is orbiting in an unusual place in its star system, and it’s leading researchers to revive a long-debated view of how giant planets can form. “My first reaction was, there’s no ...

Astronomers at the Center for Astrophysics | Harvard & Smithsonian have captured what may be the biggest planet-forming disk ever seen around a young star; and it looks unexpectedly wild. Using NASA’s ...

ALMA, located in the Chilean Atacama desert, is the most powerful telescope for observing the cool Universe — molecular gas and dust. ALMA studies the building blocks of stars, planetary systems, ...
