Woah, this nebula's out of this world ;) Translated from Latin, nebula literally means cloud. This cloud, however, is made up of dust, hydrogen and helium gas, and plasma, and it forms when some of the interstellar medium collapse and clump together. This hourglass shape is very typical of nebulae. Scientists like to study them to learn more about how stars or planets are formed. #stellar #nebula #gassy #space #discovery
