It's a Christmas gift from NASA's DART. engineering

DRACO is a high-resolution camera engineered to capture images of the asteroid Didymos and its moonlet asteroid Dimorphos, as well as support the spacecraft’s DRACO's images were taken about 2 million miles from Earth and showcase about a dozen stars near where the constellations Perseus, Aries, and Taurus intersect.

But the images are not just aesthetically pleasing. The DART navigation team at NASA’s Jet Propulsion Laboratory in California used the stars in the image to extrapolate how DRACO was oriented. Once that was established, the DART team could accurately move the spacecraft to point DRACO at objects of interest whose images could be used to identifyNASA/Johns Hopkins APL

NASA also explained how before the images were sent back,"scientists and engineers at the mission operations center at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, held their breath in anticipation." This is because the spacecraft’s telescopic instrument is very sensitive to movements as small as 5 millionths of a meter, meaning something could have easily gone wrong.
