Summary:
- Astronomers have detected small pebble-sized objects around two young stars, providing evidence that these pebbles are the building blocks of planets.
- The pebbles were detected using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope, which can observe the faint radio waves emitted by these tiny particles.
- This discovery helps scientists understand how planets form from the dust and gas in the disks surrounding young stars, a process that has been difficult to observe directly.
