Hilma af Klint, What a Human Being Is, 1910
"The Helix Nebula is a large planetary nebula located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae. The estimated distance is about 215 parsecs or 700 light-years. It is similar in appearance to the Ring Nebula, whose size, age, and physical characteristics are similar to the Dumbbell Nebula, varying only in its relative proximity and the appearance from the equatorial viewing angle."

"More than 2,800 people from my company took over a street in South San Francisco, and made a dna helix chain all the way down. Yes, the helix is made entirely of people! This is a helicopter view."
