This is the Orion Nebula, a vast stellar nursery located 1,500 light-years away. We have the Spitzer Space Telescope and its infrared camera to thanks for this incredible image, which pretty much shatters the scale for gorgeous cosmic vistas.
There's just so much to love about this image - the swirling interplay of reds and greens, the hidden constellations peeking through the clouds, the little dots of blues and violets, and that massive blinding light at the center of it all. But enough cosmic-style art appreciation, let's go to NASA for some scientific context:
This stunning false-color view spans about 40 light-years across the region, constructed using infrared data from the Spitzer Space Telescope. Compared to its visual wavelength appearance, the brightest portion of the nebula is likewise centered on Orion's young, massive, hot stars, known as the Trapezium Cluster. But the infrared image also detects the nebula's many protostars, still in the process of formation, seen here in red hues. In fact, red spots along the dark dusty filament to the left of the bright cluster include the protostar cataloged as HOPS 68, recently found to have crystals of the silicate mineral olivine within its protostellar envelope.
