COSMIC MESSAGE

Massive stars form in regions like Sharpless 212, an open cluster shown here in hydrogen and sulfur light. The bright stars in the center ionize surrounding hydrogen atoms, creating an HII region that glows red as the atoms recombine. This image helps astronomers study the environments where the most massive stars are born.
