Nebulicious!
UCLA astronomers have spotted a double helix nebula near the center of the Milky Way. Their research was published today in Nature. Very interesting, according to Prof. Mark Morris (physics and astronomy), the formation is caused by a twisting torsional wave along the strong magnetic field near the center of our galaxy. What causes the twisting you ask?
Orbiting the black hole like the rings of Saturn, several light years away, is a massive disk of gas called the circumnuclear disk; Morris hypothesizes that the magnetic field lines are anchored in this disk. The disk orbits the black hole approximateonce every 10,000 years.There ya go. Exactly what I thought. Hehehe
Here's a peek, and a link to the UCLA article.
