  "content": "**Astronomy Picture of the Day**\n\n19 May 2026\n\n**NGC 2170: The Angel Nebula**\n\nImage: https://apod.nasa.gov/apod/image/2605/Angel_Marriott_1707.jpg\n\nCredit: Not provided\n\nIs this a painting or a photograph? In this celestial abstract art composed with a cosmic brush, dusty nebula NGC 2170 , also known as the Angel Nebula, shines just above the image center. Reflecting the light of nearby hot stars, NGC 2170 is joined by other bluish reflection nebulae, a red emission region, many dark absorption nebulae , and a backdrop of colorful stars . Like the common household items that abstract painters often choose for their subjects, the clouds of gas, dust, and hot stars featured here are also commonly found in a setting like this one -- a massive, star-forming molecular cloud in the constellation of the Unicorn ( Monoceros ). The giant molecular cloud Mon R2 , is impressively close, estimated to be only 2,400 light-years or so away. At that distance, this canvas would be over 60 light-year s across.\n\n#APOD #NGC2170 #AngelNebula #Monoceros #MonR2 #ReflectionNebula\n\nhttps://apod.nasa.gov/apod/ap260519.html\n",
