Charon seen for first time.

Pluto's largest moon, Charon, was spotted by NASA's New Horizons spacecraft. Charon was discovered in 1978 by James Christy.

I'll point out that Charon has been imaged before by other devices, just not by New Horizons.

Of course we've known it was there for 35 years. It was only visible as a "bump" moving around Pluto back in 1978 when it was discovered using the 1.55-meter Kaj Strand Astrometric Reflector at the U.S. Naval Observatory’s Flagstaff Station.

Charon is visible for the first time in pictures taken by the Pluto-bound New Horizons spacecraft.

No Pluto and Charon have been individually resolved by Hubble...
