JWST reveals the chemistry of disks around young stars where rocky planets form
Researchers using the James Webb Space Telescope (JWST) have taken a first look at their data that probe the chemistry of the regions of disks around young stars where rocky planets form. Already at that stage, the data reveal ...

Tracing the history of water in planet formation back to the interstellar medium
Scientists studying a nearby protostar have detected the presence of water in its circumstellar disk. The new observations made with the Atacama Large Millimeter/submillimeter Array (ALMA) mark the first detection of water ...

Stars can eat their planets, and spit them back out again
As tragic as it is, engulfment of a planetary object by its stellar parent is a common scenario throughout the universe. But it doesn't have to end in doom. A team of astrophysicists have used computer simulations to discover ...

Astronomers come closer to understanding how Mercury formed
Simulations of the formation of the solar system have been largely successful. They are able to replicate the positions of all the major planets along with their orbital parameters. But current simulations have an extreme ...

Scientists unveil a unified theory for rocky planet formation
A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of exoplanets a few times more massive than Earth that are the most abundant type of planet in the galaxy.

A model-independent method to weigh protoplanetary disks
Astronomers have found a way to directly measure the amount of gas in protoplanetary disks without needing to make assumptions about the relative amounts of different types of gas, making this method more accurate and robust ...

Shift to ultraviolet-driven chemistry in planet-forming disks marks beginning of late-stage planet formation
The chemistry of planet formation has fascinated researchers for decades because the chemical reservoir in protoplanetary disks—the dust and gas from which planets form—directly impacts planet composition and potential ...
