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.

NASA has published a photo of the spiral galaxy NGC 5714, located in the constellation of Bootes at a distance of about 130 million light years from Earth.

The NGC 5714 made by the Hubble telescope using the ACS camera.

With such a perspective is not visible spiral structure of NGC 5714: visible a region of a blue color and a bright center.

As noted on the NASA website, in 2003 in the spiral galaxy flashed supernova SN 2003dr in the spectrum which recorded a significant calcium content.
