Galaxies, Stars, & Black Holes

News & Articles

The bright-white, diffuse glow of an elliptical galaxy sits at image center. The galaxy's core appears as an intense-white circle that gets more diffuse as you move outward from the core. A rusty-red, diffuse cloud is visible to the upper-left of the galaxy. It extends to the upper-left corner of the image, where it is very faint. Black background dotted with foreground stars and distant galaxies.

This illustration is awash in bright blues, with only areas of the black background of space peeking out near the edges. Just above center is a large white spiral galaxy that is forming within a large cloud of blue gas. Its spiral arms twirl clockwise. Immediately around the galaxy’s edges are larger light blue dots. The gas appears thicker and brighter blue below the galaxy and toward the bottom left in what looks like a loose, extended column. Other wispy blue gas appears all around the galaxy, extending to every edge of the illustration. There are two additional spiral galaxies, though they are about half the size of the one at the center. They appear toward the top left and bottom right, and both are connected to regions of blue gas. Several bright knots dot the brightest blue areas near the center, and toward the top right. The background is clearer and more obviously black along a wider area at the left edge, a sliver along the top right, and in triangles toward the bottom right corner.
