   Type Ia supernova. At the core of a planetary nebula, Henize 2-428, two white dwarf stars slightly under one solar mass each are expected to merge and create a Type Ia supernova destroying both in about 700 million years (artist's impression). A Type Ia supernova (read: "type one-A") is a type of supernova that occurs in binary systems (two ...

6. 5.56×45mm NATO - Wikipedia

   en.wikipedia.org/wiki/5.56×45mm_NATO

   The 5.56×45mm NATO standard SS109/M855 cartridge was designed for maximum performance when fired from a 508 mm (20.0 in) long barrel, as was the original 5.56 mm M193 cartridge. Experiments with longer length barrels up to 610 mm (24.0 in) resulted in no improvement or a decrease in muzzle velocities for the SS109/M855 cartridge.
