Magnetic forces at the center of the galaxy have twisted a nebula into the shape of DNA, the first time it has been observed in the cosmos.
The DNA nebula is about 80 light-years long and about 300 light-years from the supermassive black hole at the center of the Milky Way.
Magnetic field lines at the galactic center are about 1,000 times stronger than on Earth. They run perpendicular to the black hole, but parallel through the nebula. Scientists think that twisting of these lines, by a giant gas disk that orbits the black hole several light-years away, is what causes the double helix shape.
Well - 'As Above, So Below' - from cellular to cosmic DNA, the pattern, the connectivity, is the same. Evolution works on all levels.
