If you think outer space is nice and clean, think again. Recent research by an Australian-Turkish team shows that there is plenty of grease in space. Yuck! Just like you might see on polluted streets here on earth, space has its fair share of soot and dirt. While this grease has existed for millions of years, it is an exciting recent discovery for scientists. Why? It could be the first step in figuring out how much carbon exists in space, one of the main ingredients of stars and planets. Carbon exists in different forms in space, from its pure form to sticky kinds, which was discovered in this study. Spaceships can expect to be coated by this sticky carbon as they pass through space. This discovery also brings scientists one step closer to answering the question of how dust forms, evolves, or gets destroyed in space.
