| Rationale |
No free licensed or public domain alternatives known to exist to show in an X-ray image, made using 16 days of observations by NASA’s Chandra X-ray Observatory, where researchers filtered the data to brighten the contrast of edges, making subtle details more obvious, that a wave of hot gas twice as wide as the Milky Way galaxy called "the bay" (ovaled) is roiling the nearby Perseus galaxy cluster about 2017. |
