Meet NGC 2516, the 500-parsec-long open cluster (VIDEO)
Caption
A team of astrophysicists led by Princeton University's Luke Bouma has confirmed that open cluster NGC 2516, also known as the Southern Beehive, extends at least 1,600 light-years -- 500 parsecs -- from tip to tip. To an Earth-based stargazer, that would look as big as 40 full moons, side by side, stretching across the sky.
