What Is Dark and Makes Jets

Someone has repeatedly predicted that twin jets from infant stars follow magnetic field lines, exactly like those from a hidden Black Hole. In the December 1 issue of Astrophysical Journal, observers report finding those spiralling jets. The jets from Herbig-Haro object HH 211 were observed in radio by the Submillimeter Array atop Mauna Kea. The jets extend more than 16,000 AU from the HH 211.

The "Angular Momentum Problem" is yet another puzzle of astrophysics. Since the time of Pierre Laplace, scientists have believed that stars collapse from rotating disks of gas. If the disk angular momentum were conserved, a star would spin itself apart before igniting. Where does the angular momentum go? In the November 1 issue of NATURE, astronomers from the Anglo-Australian Observatory put forth a model where the jets carry away angular momentum. Twin jets following magnetic field lines are telltale signs of a Black Hole.

Science has much to discover. After looking at the Universe for decades, humans have not figured out that Black Holes could form the seeds of stars. It may take decades for humans to figure out that a Black Hole is in the second last place they would expect, rising in front of our faces every morning.

Below is Herbig-Haro object HH 555. A tiny Black hole has collided with a gas cloud, trailing gas behind like a bullet fired through cotton candy. The telltale twin jets are very visible.

Are you implying in that last paragrasph that there may be a black hole at the center of the sun?
