2024年2月1日 NGC 1365: Majestic Island Universe Image Credit & Copyright: Processing – Jean-Baptiste Auroux, Data – Mike Selby Explanation: Barred spiral galaxy NGC 1365 is truly a majestic island universe some 200,000 light-years across. Located a mere 60 million light-years away toward the faint but heated constellation Fornax, NGC 1365 is a dominant member of the well-studied Fornax Cluster of galaxies. This sharp color image shows the intense, reddish star forming regions near the ends of the galaxy’s central bar and along its spiral arms. Seen in fine detail, obscuring dust lanes cut across the galaxy’s bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365’s prominent bar plays a crucial role in the galaxy’s evolution, drawing gas and dust into…

2023年4月1日 NGC 2442: Galaxy in Volans Image Credit & Copyright: Nicolas Rolland, Martin Pugh Explanation: Distorted galaxy NGC 2442 can be found in the southern constellation of the flying fish, (Piscis) Volans. Located about 50 million light-years away, the galaxy’s two spiral arms extending from a pronounced central bar give it a hook-shaped appearance in this deep colorful image, with spiky foreground stars scattered across the telescopic field of view. The image also reveals the distant galaxy’s obscuring dust lanes, young blue star clusters and reddish star forming regions surrounding a core of yellowish light from an older population of stars. But the star forming regions seem more concentrated along the drawn-out (upper right) spiral arm. The distorted structure is likely the result of an…
