Our @NASAHubble Space Telescope spotted a red spiral galaxy that’s similar in size to our own galaxy, the Milky Way, at just over 100,000 light-years across. Similar to the Milky Way, its spiral arms are dotted with blue regions, indicating ongoing star formation. The blue patches house hot, young stars in the process of forming, while the older, cooler stars populating the galaxy’s center cause it to appear redder in color.
While its relative proximity to Earth makes it an ideal target for professional astronomers to study its active nucleus in more detail, its big apparent size in the night sky and its brightness also make it a beautiful target for amateur astronomers.
