(The quantity you type in the box is for this card. But it's OK to click the price button that reflects your total quantity of any of our cards)
*text from back of card* - The Trifid Nebula is in the constellation Sagittarius. It is one of the most remarkably detailed clouds of nebulosity in the Milky Way. The dark dust lanes that divide it into three parts give it the name Trifid.
The bright red color is created as the gas cloud is charged by the hot stars embedded in it. The blue portion of the nebula is not charged particles but is surrounding dust reflecting the light of nearby hot stars.
