Antennae Galaxies 소개
설명
NGC 4039 is the southern component of the Antennae Galaxies in Corvus, about 45 million light-years away. Together with NGC 4038 (C60), this merging pair displays dramatic tidal tails and intense starburst activity from the ongoing collision.
관측 팁
Visually inseparable from C60 in amateur telescopes. The merged cores appear as a single, irregular, bright glow. See C60 for detailed observing tips.
역사
Discovered by William Herschel on February 7, 1785, the same night as NGC 4038. The two were originally cataloged as separate objects but are now understood to be a single interacting system.
재미있는 사실
Computer simulations suggest the two galaxies began interacting about 600 million years ago and will eventually merge into a single elliptical galaxy over the next 400 million years.
