De Stella Nova

Kepler’s 1604 naked eyes saw the birth

of a star, actually that supernova was

the star’s death. With no telescope invented,

he watched the spiral galaxy’s Milky center

explode into night, 20,000 light years away.

This is the remnant of Kepler’s supernova, the famous explosion that was discovered by Johannes Kepler in 1604. The red, green and blue colors show low, intermediate and high energy X-rays observed with NASA’s Chandra X-ray Observatory, and the star field is from the Digitized Sky Survey. http://www.nasa.gov/mission_pages/chandra/multimedia/kepler2013.html
