Molecules in the disc around the star IRS 48 (composite)

This composite image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows where various gas molecules were found in the disc around the IRS 48 star, also known as Oph-IRS 48. The disc contains a cashew-nut-shaped region in its southern part, which traps millimetre-sized dust grains that can come together and grow into kilometre-sized objects like comets, asteroids and potentially even planets. Recent observations spotted several complex organic molecules in this region, including formaldehyde (orange), methanol (green) and dimethyl ether (blue), the last being the largest molecule found in a planet-forming disc to date. The emission signaling the presence of these molecules is clearly stronger in the disc’s dust trap, while carbon monoxide gas (purple) is present in the entire gas disc. The location of the central star is marked with a star.
