Title:
SH2 136: A Spooky Nebula
Explanation:
The dark nebula SH2-136 appears to be celebrating Halloween [ http://en.wikipedia…] all of the time. The complex process of star formation [ http://antwrp.gsfc.…] create dust [ http://antwrp.gsfc.…] clouds of many shapes [ http://antwrp.gsfc.…] and sizes [ http://antwrp.gsfc.…] -- it is human perception [ http://www.johnsado…] that might identify a ghoulish creature [ http://www.benjerry…], on the right of the above image [ http://www.caelumob…], chasing humans. Halloween's modern celebration retains historic roots in dressing to scare away the spirits of the dead. Since the fifth century BC, Halloween [ http://teacherlink.…] has been celebrated as a cross-quarter day [ http://www.astronom…], a day halfway between an equinox [ http://antwrp.gsfc.…] (equal day / equal night) and a solstice [ http://www.candlegr…] (minimum day / maximum night in the northern hemisphere). With our modern calendar, however, the real cross-quarter day [ http://en.wikipedia…] will occur next week. Other cross-quarter markers include Groundhog Day [ http://www.groundho…] and Walpurgis Night [ http://en.wikipedia…].
