Typically, stars are not visible in photographs of astronauts on spacewalks because the light reflected off astronaut suits, the International Space Station, and even the Earth is so bright that it drowns out the dimmer light of the background stars. This is similar to trying to see the night sky stars from the middle of a city on Earth - the brighter lights from the buildings drown out the stars. But don't worry; the stars are still there!

Astronauts often photograph the night sky away from the Sun's glare, and with the right exposure settings on their camera, and gets some stunning images.
