The Dust Monster in IC 1396

Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation regionmay appear to take on foreboding forms, somenearly human. The only real monster here, however, is a bright young star too far fromEarth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the featured imageJetsand winds of particles emitted from this star are also pushing away ambient gas and dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moons.
