This image from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the dust trap in the disc that surrounds the system Oph-IRS 48. The dust trap provides a safe haven for tiny particles in the disc, allowing them to clump together and grow to sizes that allow them to survive on their own. The green region shows where the larger particles are located (millimetre-sized) and is the dust trap seen discovered by ALMA. The orange ring shows observations of much finer dust particles (micron-sized) using the VISIR instrument on ESO's Very Large Telescope.
