Music Music Narrator: Not far from the colorful nebula M78, in a dark cloud where stars are being formed, a young star announced its presence by lighting up a nebula never cataloged before. Astronomers first noticed McNeil's Nebula in 2003, which drew their attention to the young star illuminating it, named V1647 Orionis. The star sports a pair on intense X-ray "hot spots" thousands of times hotter than the rest of the star. These spots are thought to be the footprints of streams that transfer gas from a disk that still surrounds the young star. Scientists think that magnetic reconnection events-- the energy source for outbursts from our own sun--channel and drive the gas flows. The star, which spins once in about a day, rotates faster than the disk, and constantly winds up the magnetic fields, which release a great deal of energy when they snap back into lower-energy states. This protostar's X-ray variations are giving astronomers a rare glimpse of energetic phenomena accompanying the "toddler" phase of a low-mass star. Music. Beeping Beeping
