Infant planets are ravenous little blighters that quickly devour what remains of the star-circling gas and dust clouds in which they form. The gas in these protoplanetary disks disappears rapidly, ...

How does fine dust aggregate into building blocks that ultimately form entire planets like our Earth? A research team led by ...

Star formation is an intricate process that transforms vast molecular clouds into newborn stars, often accompanied by the formation of circumstellar discs composed of gas and dust. These ...

Artist’s concept of a planet-forming disk, like the thirty studied for the ALMA AGE-PRO survey. The lifetime of the gas within the disk determines the timescale for planetary growth. An international ...

What can a protoplanetary disk comprised of carbon dioxide teach scientists about a solar system’s formation and evolution? This is what a recent study published in Astronomy & Astrophysics hopes to ...

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, ...

This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc, volatile gases are frozen out as ice, which contains complex organic molecules.
