Outburst from a Young Star
The unchanging heavens are actually quite dynamic. One particular change in the heavens was the rare appearance of a new nebula around a young star in the constellation of Orion. This nebula, shown above, is called McNeil's Nebula, for Jay McNeil, an amateur astronomer who discovered it in January 2004 using a 3-inch telescope. Along with the appearance of this nebula, a Chandra observation showed that the X-ray emission from the erupting star increased fifty-fold. The X-ray observations suggest that outburst is produced by the sudden infall of matter from an orbiting disk of gas onto the surface of the star.
