An unusual globule 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 region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the above image. Jets and 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.

Qiandao Lake is a man-made lake located in Chun’an County, China, where archeologists have discovered in 2001 ruins of an underwater city. The city is at a depth of 26-40 meters and was named “Lion City”. There would have been 290 000 people living in this city during more than 1300 years. Touristic expeditions are projected.
