The Tycho supernova remnant in the Milky Way, produced by the explosion of a white dwarf star in our galaxy. Low-energy X-rays (red) show expanding debris from the supernova explosion and high energy X-rays (blue) show the blast wave, a shell of extremely energetic electrons. These high-energy X-rays show a pattern of X-ray "stripes" never seen in a supernova remnant.
By combining observations from several instruments, we can see an initial solar eruption and the ensuing, large cloud of particles that blasted into space over a 10-hour period (Feb. 9-10, 2012). A close look at the orange-colored Sun image in extreme UV light shows a filament that broke away from the Sun to the right. Credit: NASA/GSFC/STEREO
Celestial Fireworks - Hubble by Deep Space Photography - Resembling the puffs of smoke and sparks from a summer fireworks display in this image from NASA's Hubble Space Telescope, these delicate filaments are actually sheets of debris from a stellar explosion in a neighboring galaxy.
