The 13-foot-wide moon.Image: Roger An astrophotographer has spotted what looks to be a moon orbiting the comet 67P/Churyumov-Gerasimenko, the target of the European Space Agency’s Rosetta Mission.
Aside from producing lots of interesting data as well as thrills, it also sent many images of the comet back to Earth.
The Rosetta mission was the first to land a human-made object on a comet (though the landing was rocky).
Rosetta watched the comet spew gas and dust as it neared the Sun, creating the coma, beginning in the summer of 2015.
Astrophotographer Jacint Roger found the speck while mining the Rosetta image archives to create one of his gifs.
The object is the largest such chunk found around the comet yet, according to an ESA release.
Many space missions, from the Mars rovers to Rosetta, have sent countless images back to Earth that are free for you to access.
