Tucked away in the constellation Centaurus, a colorful bubble of gas and dust resembling a jellyfish, is all that remains of a great star.
Fireworks in D

The letter D is outlined in this celestial fireworks display. The colorful filaments seen in this NASA Hubble Space Telescope image of N49 are all that’s left of a supernova explosion that took place thousands of years ago in the Large Magellanic Cloud. This supernova remnant is called N 49, or DEM L 190. Inside these sheets of glowing star debris lies a powerful, spinning neutron star called a pulsar. Pulsars give off regular pulses of energy like the ticking of a very precise clock. After the supernova blows off the outer layers of the star, it collapses under its own gravity. The star collapses so much that the protons and electrons spinning around the atoms of the star combine to form neutrons. A neutron star is very dense. Imagine our entire Sun packed into an area of just 20 kilometers (12 miles) in diameter! Gravity is very strong on a neutron star. On Earth, a spoonful of neutron star material would weigh billions of tons. The magnetic field of N 49 is super strong, trillions of times stronger than Earth’s, putting it in special class of bizarre celestial objects called magnetars.
Curling C

Galaxy interactions create all sorts of curls and odd shapes. In this NASA Hubble Space Telescope image of UGC 4881, the letter ‘C’ spirals out in deep space.
