About this image

The red dots scattered throughout the landscape around Westerlund 2 are a rich population of newly forming stars still wrapped in their gas-and-dust cocoons. These tiny, faint stars are between 1 million and 2 million years old and have not yet ignited the hydrogen in their cores. Hubble's near-infrared vision allows astronomers to identify these fledgling stars.
