APOD: 2023 November 22 - IC 342: Hidden Galaxy in Camelopardalis Discover the cosmos!Each day a different image or photograph of our fascinating universe isfeatured, along with a brief explanation written by a professional astronomer. 2023 November 22 IC 342: Hidden Galaxy in Camelopardalis Image Credit &Copyright: Steve Cannistra Explanation: Similarin size to large, bright spiral galaxies in our neighborhood,IC 342is a mere 10 million light-yearsdistantin the long-necked, northern constellationCamelopardalis.A sprawling island universe,IC 342 would otherwise be a prominent galaxy in our night sky,but it is hidden from clear view and onlyglimpsed through the veil of stars, gas and dust cloudsalong the plane of our own Milky Way galaxy.Even though IC 342's light is dimmed and reddened by interveningcosmic clouds,thissharp telescopic imagetraces the galaxy's own obscuring dust, young star clusters, andglowing star forming regions along spiral arms that wind far fromthe galaxy's core.IC 342 has undergone a recent burst ofstar formationactivity and is close enough to have gravitationally influencedthe evolution of thelocal groupof galaxies and the Milky Way.
