Image: Hubble’s curious case of a calcium-rich supernova

This image, captured by the Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope, shows the spiral galaxy NGC 5714, about 130 million light-years away in the constellation of Boötes (the Herdsman). NGC 5714 is classified as an Sc spiral galaxy, but its spiral arms—the dominating feature of spiral galaxies—are almost impossible to see, as NGC 5714 presents itself at an almost perfectly edge-on angle.
