Space Helix!



Cosmic 'DNA': Double Helix Spotted in Space
Magnetic forces at the center of the galaxy have twisted a nebula into the shape of DNA, a new study reveals.

The double helix shape is commonly seen inside living organisms, but this is the first time it has been observed in the cosmos.

"Nobody has ever seen anything like that before in the cosmic realm," said the study's lead author Mark Morris of UCLA. "Most nebulae are either spiral galaxies full of stars or formless amorphous conglomerations of dust and gas—space weather. What we see indicates a high degree of order."

These observations, made with NASA's Spitzer Space Telescope, are detailed in the March 16 issue of the journal Nature.

Hat tip to Ruth for the heads up.

"Double helix" must be the secret word for the day. NPR had this delightful tidbit about the double helix
