The latest images from NASA reveal the colorful and delicate Veil Nebula. Once a supernova explosion that may have been seen by humans approximately 8000 years ago, the Veil Nebula is donut-shaped and located in the Cygnus constellation — which means swan.
At one time the nebula would have lit-up the northern night sky as the dying star exploded.
This video helps you imagine where the Nebula exists, in the Northern Sky:
The Veil Nebula was named because it appears like light, flowing material blowing in the breeze. Within the debris and gas formations, scientists can make out some details — thanks to the power of the Hubble telescope, a space-based and solar powered optical telescope.
In this video, you can take virtual tour over the Veil Nebula in 3D, which is possible due to a mosaic effect of six photographs that show a section of the nebula that is two light years wide:
Do you notice the many layers of colored gas that have taken-on a wispy or watery appearance? This is what is left over when a star 20-times-larger than ours detonates. The brighter areas show shock waves left over in the denser material.
The varying colors respond to different elements exposed to great amounts of heat and pressure. Red is hydrogen, green/yellow is sulfur, and blue is oxygen.
Scientists will compare these most recent photos of Veil Nebula with some taken in 1997, some 18 years ago, to see how far the matter has expanded.
