False colour images of “Parker’s star” and its surrounding nebula Pa30 that make-up the remnants from the SN 1181 AD event. The colours represent the infrared, optical, and UV light. The contours in the central image show X-ray emission. At the distance of 7,500 light years, 45 arc seconds on the sky translate to 100,000 astronomical units. One astronomical unit is the average distance between Earth and the Sun, which is about 93 million miles or 150 million kilometers. (IMAGE)
