What is the Orion Nebula?

Glowing star-forming cloud, visible to the naked eye as the fuzzy middle “star” of Orion’s sword.

Worth knowing about the Orion Nebula

You see the Orion Nebula as it was 1,272 years ago.

Why it stands out
The closest large star-forming region to Earth, the best-studied stellar nursery in the sky.
What it is
A glowing cloud of gas and dust actively forming hundreds of new stars; at its heart is the Trapezium, a tight knot of young brilliant stars.
How we know: Infrared telescopes see through the dust to spot hundreds of still-forming protostars, some wrapped in their own planet-building discs.
