Beacon of Light

14 hours ago 3

A spiral galaxy shown in mid-infrared light. The image is dominated by an extremely bright glow from the galaxy’s nucleus. Six large and two smaller rays of light emit from the center, which are diffraction spikes created by the telescope’s optics. The galaxy’s spiral arms are visible by two lines of glowing orange bubbles which whirl out into the disc. Swirling blue clouds of dust make up the rest of the galaxy.

This latest Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope features Messier 77 (M77), a barred spiral galaxy famous and appreciated among astronomers for its combination of relative proximity and spectacular features to study. It is located 45 million light-years away in the constellation Cetus (The Whale).
