This diagram shows the 100-million-year-long trajectory of the Smith Cloud as it arcs out of the plane of our Milky Way Galaxy and then returns like a boomerang. Hubble measurements show that the cloud, because of its chemical composition, came out of a region near the edge of the Galaxy’s disk of stars 70 million years ago. The cloud is now stretched into the shape of a comet by gravity and gas pressure. Following a ballistic path, the cloud will fall back into the disk and trigger new…

NGC 602 is a bright open cluster of stars located in the SMC, a satellite galaxy to the Milky Way. Radiation & shock waves from the stars have pushed away much of the lighter surrounding gas & dust that compose the nebula known as N90
