Butterfly Nebula glows red in spectacular image from NASA’s Spitzer Space Telescope

A butterfly-shaped stellar nursery twinkles in red and orange in a beautiful photo recently released by NASA.

The agency’s Spitzer Space Telescope captured the image of the aptly named Butterfly Nebula, also known as Westerhout 40 (W40), as part of the Massive Young Stellar Clusters Study in Infrared and X-rays survey in 2014. W40 is located some 1,400 light-years from the sun — roughly the same distance as the Orion Nebula, but in the opposite direction in the sky.
