Orion

Helion Energy, the Washington-based fusion startup backed by OpenAI's Sam Altman, has reportedly revised its timeline for delivering commercial fusion power, including its Microsoft power-purchase deal and its Orion project. Commentators are weighing what the delay means for the credibility of fusion energy's commercial promises.

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.
