Astronomy enthusiasts are highlighting Messier 78, a reflection nebula in the constellation Orion. Unlike emission nebulae that glow from ionized gas, M78 consists of interstellar dust clouds reflecting the blue light of hot young stars embedded within it, making it a textbook example of its class. The object is being shared in science-focused discussions as a striking example of how dust rather than gas can light up deep-sky environments.

Why now: Science communities are sharing striking astronomy content about a well-known deep-sky object.
