Narrator (Megan Watzke, CXC): The supernova remnant known as E0102 was one of the targets that Chandra first observed after its launch in 1999. Now, some ten years later, new X-ray data from Chandra have been used to produce this spectacular image. E0102 is located about 190 thousand light-years away in the Small Magellanic Cloud, which is one of the nearest galaxies to the Milky Way. It was created when a star that was much more massive than the sun, exploded, an event that would have been visible from the southern hemisphere on Earth over one thousand years ago. The information captured in this new image, which includes optical data from the Hubble Space Telescope, reveals new clues about the geometry of the remnant. This in turn helps astronomers better understand the details of the explosion that created the remnant we see today.
