  "content": "**Astronomy Picture of the Day**\n\n10 May 2026\n\n**Comet R3 PanSTARRS and Orion**\n\nImage: https://apod.nasa.gov/apod/image/2605/CometOrion_Perrot_960.jpg\n\nCredit: Not provided\n\nOrion never had a sword like this. As Comet C/2025 R3 (PanSTARRS) heads out of the inner Solar System, it is putting on quite a show for long exposure cameras . Currently seen toward the constellation of Orion the Hunter , the distant Orion Nebula is visible on the upper right. Comet R3 PanSTARRS is now showing two distinct tails : a short dust tail pointing toward the top of the image and a long and wavy ion tail trailing off toward the upper left. The ion tail points away from the Sun and glows blue from excited carbon monoxide . Large particles in the dust tail somewhat resist the radiation pressure that push them away from the Sun and so retain a bit of the comet's orbit. The dust tail shines by reflected sunlight . The featured image was taken a few days ago from France 's Reunion Island in the southern Indian Ocean .\n\n#APOD #CometR3 #PanSTARRS #CometC2025R3 #Orion #OrionNebula\n\nhttps://apod.nasa.gov/apod/ap260510.html\n",
