A #Protoplanetary #Disk is a rotating circumstellar disk of dense gas and dust surrounding a young, newly formed star.
This disk is where planets, moons, and other celestial bodies are believed to form through the process of accretion.

Protoplanetary disks from #ALMA.
Though we have learned much about #exoplanets, there is still much we do not know about the steps of planet formation and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered.
Astronomers have conducted one of the deepest surveys ever of #protoplanetary disks, the planet-forming dust belts around young #stars.
The disks are as diverse as are the forming planetary systems.

For decades, scientists have debated how small #exoplanets form.
New model suggests that #planets form in narrow rings at specific locations in the #protoplanetary disk, making #planet formation more organized than previously believed.
Simulations also imply that up to about 1% of super-Earth and mini-Neptune systems could host Earth-like planets within the #habitable zone.
This implies an occurrence rate of approximately one Earth-like planet per 300 sun-like stars.

Astronomers have made a breakthrough in revealing how #planets are made.
By observing water vapor in #protoplanetary disks, #JWST observations have confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.
Theories have long proposed that icy pebbles forming in the cold, outer disk regions should be the fundamental seeds of #planet formation.

Solving the mystery of how #planets like Earth form is an important question for understanding the origin of life.
Planets are thought to form when interstellar dust and gas collect in a #protoplanetary disk surrounding a #protostar, but it has been unclear how #planet formation begins.
By observing protoplanetary disks without dark rings, astronomers can study systems where giant planets have not yet formed.
