Why this matters
This scene highlights deep-space objects. The same physics that lets us photograph it also lets us predict where objects will be tomorrow — which is exactly what real-time tracking is built on.

This connects to what you can track in real time on our 3D globe — explore Deep Space galaxy map. Or open the live globe to watch flights, satellites, the ISS and spacecraft move right now.
The science, from NASA's Astronomy Picture of the Day
The Great Nebula in Orion, an immense, nearby starbirth region, is one the most famous of all astronomical nebulas. Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the featured deep image in assigned colors highlighted by emission in hydrogen, wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye near the easily identifiable belt of three stars in the popular constellation Orion. In addition to housing a bright open cluster of stars known as the Trapezium, the Orion Nebula contains many stellar nurseries. These nurseries contain much hydrogen gas, hot young stars, proplyds, and stellar jets spewing material at high speeds. Also known as M42, the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun.Tomorrow's picture: open space
