  "content": "**Astronomy Picture of the Day**\n\n09 June 2026\n\n**Thor's Helmet**\n\nImage: https://apod.nasa.gov/apod/image/2606/Thor_Drudis_4389.jpg\n\nCredit: Not provided\n\nThor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing -like appendages. Heroically sized even for a Norse god , Thor's Helmet is about 30 light-years across. In fact, the cosmic head-covering is more like an interstellar bubble , blown by a fast wind from the bright, massive star near the bubble's center. Known as a Wolf-Rayet star , the central star is an extremely hot giant thought to be in a brief, pre- supernova stage of evolution . NGC 2359 is located about 15,000 light-years away toward the constellation of the Great Overdog . This sharp image is a combination of deep images taken in light emitted by hydrogen (red) and oxygen (blue). The star in the center of Thor's Helmet is expected to explode in a spectacular supernova sometime within the next few thousand years.\n\n#APOD #Astrophotography #Science #NASAInspires #Space\n\nhttps://apod.nasa.gov/apod/ap260609.html\n",
