Nothing low-key about stellar births 🔐 ⁣ ⁣ A reflection nebula in the constellation Orion is captured here by NASAHubble. Reflection nebulae glow because they are made up of extremely tiny particles of solid matter, up to 10 or even 100 times smaller than dust particles on Earth. These particles diffuse the light around them, giving the nebula a second-hand glow that’s typically bluish (like our sky). ⁣ ⁣ The nebula is a relic of a recent star formation – made up of debris left over from the formation of the newborn star visible at the center of the image.
