The Great Carina Nebula

APOD: 2024 April 19 - The Great Carina Nebula 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. 2024 April 19 The Great Carina Nebula Image Credit &Copyright:Demison Lopes Explanation: A jewel of the southern sky,the GreatCarina Nebula is more modestly known as NGC 3372.One of ourGalaxy'slargest star forming regions, it spans over 300 light-years.Like the smaller, more northerly Great Orion Nebula, the Carina Nebula is easily visible to the unaided eye.But at a distance of 7,500 light-years it lies some 5 times farther away.This stunning telescopic view revealsremarkable details of the region's glowing filaments of interstellar gasand obscuring cosmic dust clouds.TheCarina Nebulais home to young, extremely massive stars, includingthe still enigmatic variable Eta Carinae, astar with well over 100 times the mass of the Sun. Eta Carinaeis the bright star above the central dark notch in this field and left of thedusty Keyhole Nebula (NGC 3324).

Facing NGC 1232

APOD: 2024 April 18 - Facing NGC 1232 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. 2024 April 18 Facing NGC 1232 Image Credit &Copyright:Neil Corke Explanation: From our vantage point in theMilky Way Galaxy,we see NGC 1232 face-on.Nearly 200,000 light-years across, the big, beautifulspiral galaxyis located some 47 million light-years away in the flowing southernconstellation of Eridanus.This sharp, multi-color, telescopic imageof NGC 1232 includes remarkable details of the distant island universe.From the core outward, the galaxy'scolors change from the yellowishlight of old stars in the center to young blue starclusters and reddish star forming regions along the grand, sweepingspiral arms.NGC 1232's apparent, small, barred-spiral companion galaxyis cataloged as NGC 1232A.Distance estimates place it much farther though,around 300 million light-years away, and unlikely to beinteracting with NGC 1232. Of course, the prominent bright star with the spiky appearanceis much closer than NGC 1232 and lies well within our own Milky Way.
