“Oxygen and neon are the most abundant elements in the remnant, evidence that the star that exploded was at least ten times as massive as the Sun.”

“The fluffy crescent-shaped X-ray features that appear around the edge of the remnant are thought to be fragments of high-speed matter shot out from the star when it exploded, like shrapnel from a bomb. “

Color Code Energy:

Red 0.50 - 0.91 keV, Cyan 0.91 - 1.34 keV, Blue 1.34 - 3.00 keV

Color Code Energy:

Red 0.95-1.26 keV, Green 1.63-2.26 keV, Blue 4.1-6.1 keV

Load Chandra data into ds9 and use “energy cut” to show photons within a certain energy range. Save each energy cut as a separate .tiff file.

Load .tiff files made with ds9 showing “soft”, “medium” and “hard” x-rays into Image J to make final 3-color composite.
