Astrophysics Stories

An oval-shaped spiral galaxy. Its core is a compact, glowing blue spot. A bright bar of light, lined with dark reddish dust, extends horizontally to the edge of the disk. A spiral arm emerges from each end of the bar and follows the edge of the disk, lined with blue and red glowing patches of stars, to the opposite end and a little off the galaxy. A scattering of blue stars are between us and the galaxy.

The center of the image contains arcs of orange and pink that form a boat-like shape. One end of these arcs points to the top right of the image, while the other end point toward the bottom left. Another plume of orange and pink expands from the center to the top left of the image. To the right of this plume is a large cluster of white stars. There are various other white stars and a few galaxies of different sizes spread throughout the image. Ten, small, yellow circles overlaid at various points across the image indicate the positions of the ten stars surveyed in this study.

A close-up of a spiral galaxy, seen face-on. Its center is a bright white point, surrounded by a large yellowish oval with thin lines of dust swirling in it. From the sides of the oval emerge two bright spiral arms which wind through the round disk of the galaxy, filled with shining pink spots where stars are forming and more dark reddish dust. Many stars are visible in the foreground, over and around the galaxy.

Hundreds of overlapping objects at various distances are spread across this field. Galaxies’ colors vary. The majority appear orange, pink, and white, some are shades of orange or blue. Most galaxies appear as fuzzy ovals, but a few have distinctive spiral arms. At the very center is a tiny galaxy nicknamed Firefly Sparkle that looks like a long, angled, dotted line. Smaller companions are nearby.
