Astronomers have for the first time spotted a nebula in the form of a double helix--the shape of the DNA molecule. Skip to main content. Scientific American. March 21, 2006. 1 min read.

The double helix nebula is approximately 300 light years from the enormous black hole at the center of the Milky Way. (The Earth is more than 25,000 light years from the black hole at the galactic ...

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 ...

At the heart of the double-lobed Toby Jug planetary nebula is the red-giant star HR3126, which at just 50 million years old, is considerably younger than the 4.6-billion-year-old sun.

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

“Double Helix,” at Bay Street Theater, illuminates the British scientist’s contributions, which became the basis for James Watson and Francis Crick’s 1953 breakthrough.

The red giant, called HR3126, is thought to be partially responsible for the unusual double-lobed shape of the nebula. Astronomers theorize that the red giant once had a companion star, which has ...

Other ring-shaped planetary nebulas, such as the Helix Nebula (NGC 7293 in Aquarius), have also been shown to have bi-lobed structures by which we are looking "down" the end of one lobe.

While the classic helix style involves piercing the upper outer cartilage once, if you have two or three piercings stacked in a row above each other, these are called double and triple helix ...

New York — The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit.
