ShatzThe spiral galaxy IC 4633, revealed by Hubble, is linked with the dark nebula of the Chameleon region and the enigmatic South Celestial Serpent, showcasing a fascinating huge tableau.In todays Picture of the Week from Hubble, the topic is the spiral galaxy IC 4633, situated 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity, along with hosting an active galactic nucleus at its core. From our perspective, the galaxy is slanted mostly towards us, giving astronomers a fairly excellent view of its billions of stars.However, we cant fully value the features of this galaxy– at least in visible light– due to the fact that its partly concealed by a stretch of dark dust. This dark nebula becomes part of the Chameleon star-forming region, itself located only around 500 light-years from us, in a nearby part of the Milky Way galaxy. The dark clouds in the Chameleon region occupy a big location of the southern sky, covering their namesake constellation however also encroaching on neighboring constellations, like Apus. The cloud is well-studied for its treasury of young stars, especially the cloud Cha I, which has actually been imaged by Hubble and likewise by the NASA/ESA/CSA James Webb Space Telescope.The cloud overlapping IC 4633 lies east of the popular Cha I, II, and III, and has been called MW9 or the South Celestial Serpent. A vast, narrow trail of faint gas that snakes over the southern celestial pole, its a lot more subdued-looking than its neighbors. Its categorized as an incorporated flux nebula (IFN)– a cloud of gas and dust in the Milky Way galaxy thats not close to any single star, and is just faintly lit by the total light of all the galaxys stars. Hubble has no problem constructing out the South Celestial Serpent, though this image catches only a small part of it. For a showy huge object like IC 4633, amongst the South Celestial Serpents coils plainly isnt a bad place to conceal.
