![CPD continuum flux densities at 345 GHz for different planet masses and separations. The dots mark the solar system gas giants, the directly imaged planets in PDS 70 and WISPIT 2, and candidate protoplanets in disc gaps. For comparison, the distribution of fully formed gas giants is shown (top panel). The white curves display sensitivity limits. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Planet-formation.png?resize=1200%2C717&ssl=1)
[astro-ph.IM] Giant planets are often regarded as primordial protoplanetary “architects”. Their formation and interactions with planetesimals and other planets during and after the protoplanetary disc phase are key to setting […]
ALMA2040
![Current ALMA can detect the rich chemistry within the snowline around higher-mass stars, with an example spectrum shown in the top panel. For Sun-like stars, mapping across the CO snowline only ( > ∼ 10 au) is currently possible, which corresponds to the giant planet formation zone. The step changes in spatial resolution and sensitivity provided by ALMA2040 will allow us to detect and map the composition of terrestrial-planet-building material around Sun-like stars. Data from Qi et al. (2013), Andrews et al. (2016), and Booth et al. (2024a). -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Chemistry-on.png?resize=1200%2C716&ssl=1)

Chemistry On Solar System Scales
[astro-ph.IM]. The initial chemical composition of planets, primitive bodies in our solar system, and exoplanets is ultimately set by their nascent protoplanetary disks.
