- Description: The veil nebula is an expanding shell of material created when a star, about 20x the size of our sun, died in a violent explosion around
10,000 years ago. This expanding debris is located about 2400 light years from Earth. This wide-field image shows much of this expanding shell of gasses as
well as some background nebulosity.
