Reply to TIL a neutron star in the constellation Sagittarius rotates 716 times per second. by shallowblue

Some more wild facts about it:

the star has twice the mass of the sun but is only 32km across
at its equator, the surface is moving at ~24% of lightspeed (over 70,000 km/sec)

Reply to TIL that one of the top convenience stores in Japan was founded in Ohio, and that there are now only 2 locations open in the United States by 0wnzl1f3

The number (and quality) of convenience stores in Japan really surprised me - over there they aren't just a place to get a donut and coke at 3am waiting for a cab, but the main shop you go to every day.
