"name": "The screencap features a vibrant depiction of the Veil Nebula, a remnant of a supernova explosion that occurred about 7,000 years ago. The nebula is predominantly red and blue, with intricate wisps of gas and dust that create a striking visual effect against the dark backdrop of space. The image is credited to Abdullah Alharbi.\n\nBelow the image, there is a text description that provides context about the Veil Nebula. It explains that the wisps visible in the image are all that remain of a Milky Way star that exploded in a supernova. The expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to people living at the dawn of recorded history. Today, the supernova remnant, also known as the Cygnus Loop, is visible only through a small telescope directed toward the constellation of the Swan (Cygnus). The remaining Veil Nebula is physically huge, covering over five times the size of the Moon, despite being about 1,400 light-years distant.\n\n Ovis2-8B\n\n🌱 Energy used: 0.254 Wh",
