Scientists study protoplanetary disks by looking at their spectra, the wavelengths of radio waves emitted by components of the disk. Hydrogen gas is the main constituent of protoplanetary disks, but ...

Roughly 5 billion years ago Earth was in the process of forming. Gas and dust gathered with the young sun's protoplanetary disk, likely nudged a bit by the resonant gravitational pull of Jupiter and ...

Using new observations with the ALMA telescope array in Chile, researchers have compiled the most precise map of three regions in the Milky Way's Central Molecular Zone to date, providing valuable ...

Many newly formed stars are surrounded by what are called protoplanetary disks, swirling masses of warm dust and gas that can constitute the core of a developing solar system. Proof of the existence ...

Add Yahoo as a preferred source to see more of our stories on Google. A close-in image of a protoplanetary disc around a newly formed star. Many different wavelengths of light are combined and ...

(Nanowerk News) 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, ...
