No, this is not a TIE fighter gong over the sun, it is the International Space Station. And while getting a shot of the ISS over the sun is competently doable, getting that shot with Mercury in the frame is an epic effort.
Engineer and photographer Thierry Legault took this composite of the ISS, Sun and Mercury at a carefully selected location and date in Philadelphia, USA. You see during the entire 21st century there are only 14 times that Mercury goes over the sun. Add to that the precision needed to capture the exact 0.6 seconds of ISS transit and you can start understating how hard it can be.
