ALT The Rosette Nebula fills this infrared image. The nebula resembles a red flower with a halo of green leaves. The center of the flower is a rough circle filled with the blackness of space and dotted with blue stars. A streak of bright red runs partway across it. Surrounding this is a thick, irregular ring of red clouds. Encircling the red is a wide ring of green cloudy structures that give the red “flower” a scalloped edge. The green extends past the top left corner. The other three corners reveal black space, and the entire image is speckled with blue stars. The image is watermarked “Credit: NASA/JPL-Caltech/UCLA.”
