‘Space butterfly’ is home to hundreds of baby stars
What looks like a red butterfly in space is in reality a nursery for hundreds of baby stars, revealed in this infrared image from NASA’s Spitzer Space Telescope. Officially named Westerhout 40 (W40), the butterfly is a nebula—a giant cloud of gas and dust in space where new stars may form. The butterfly’s two “wings” are giant bubbles of hot, interstellar gas blowing from the hottest, most massive stars in this region.
